Hechuan District

This data comes from Baidu Map, and the final result is subject to Baidu Map data.

In ancient times, Hechuan was an important residence for the Pu people before the Ba people entered Sichuan. In the 11th century BC, Ji Fa (King Wu of Zhou) of the Zhou clan established the Western Zhou Dynasty and granted Ji Yuba the title of Duke. Bazi built the capital of Bazi at the foot of Tongliang Mountain in today's Hechuan City, named "Bazi City". In 314 BC, the Qin Dynasty established Dianjiang County, which governed present-day Hechuan and Wusheng, and Tongliang, Anyue and Yuechi counties. It was under the jurisdiction of Bajun and its administrative seat was present-day Hechuan. Dianjiang County is the earliest county name in Hechuan history. The original name of Dianjiang River is Xijiang, which means that the water where the Jialing River and Fujiang River meet in the county town overlap like clothes. The "Hanshu Geography" mistakenly records it as Dianjiang and it has been used to this day. In the Yuanjia period (424-453) of Emperor Wen of the Southern Dynasty, Emperor Wen of the Song Dynasty was promoted to Dianjiang County and established Dongdanqu County, which belonged to Liangzhou. The county was governed in today's Hechuan City. The name of Danqu comes from Danqushui (now Qujiang River). In the third year of Emperor Gong of the Western Wei Dynasty (556), it was changed to Hezhou. Hezhou was named because the Fujiang River came from Zizhou and Suizhou and merged with the Jialing River in Hechuan City. The state government is located in today's Hechuan City. In the 18th year of the founding of Emperor Wen of the Sui Dynasty (598), Hezhou was renamed Fuzhou (still named after water). In the third year of Emperor Yang's great cause in the Sui Dynasty (607), Fuzhou was renamed Fuling County, which governed Shijing, early Han Dynasty (incorporated into Qingju County), Chishui (named after the ancient name Chishui of the present-day Yanxi River, and the county seat was in the original Hechuan County Chishui Township) 3 counties. In the first year of Emperor Wude of the Tang Dynasty (618), it was renamed Hezhou and belonged to Jiannan Road. In the first year of Tianbao, Emperor Xuanzong of the Tang Dynasty (742), Hezhou was renamed Bachuan County. In the first year of Qianyuan (758) of Emperor Suzong of Tang Dynasty, it was renamed Hezhou. In the third year of Emperor Qiande of the Song Dynasty (965), Shijing County was renamed Shizhao County, and Hezhou belonged to Zizhou Road and later to Tongchuanfu Road. In the third year of Chunyou (1243), Emperor Lizong of the Song Dynasty, in order to resist the Mongolian soldiers, he built a new city on Diaoyu Mountain, 5 kilometers east of the state, and moved the seat of Hezhou and Shizhao County to Diaoyu City. In the 20th year of the Yuan Dynasty (1283), Emperor Shizu of the Yuan Dynasty abolished Changzhou (the administrative area is now Yongchuan City) and Changyuan County and Yongchuan County under its jurisdiction were merged into Dazu County, which belonged to Hezhou.

In the same year, the county offices of Hezhou and Shizhao were moved from Diaoyu City back to their original location, which belonged to Chongqing Fu Road. In the twenty-fourth year of the Yuan Dynasty (1287), Chishui County was merged into Shizhao County. Hezhou has jurisdiction over three counties: Shizhao, Tongliang (incorporated into Dazu County), and Dingyuan (established in the 22nd year of the Yuan Dynasty, governing the south of present-day Wusheng County). In the Ming Dynasty, Hezhou was subordinate to Chongqing Prefecture. In the seventh year of Hongwu's reign (1374), Taizu of the Ming Dynasty, Dazu County was separated from Hezhou and placed under the direct jurisdiction of Chongqing Prefecture. In the 14th year of Chenghua (1478) of Emperor Xiaozong of the Ming Dynasty, Anju County (under the jurisdiction of Chongqing Prefecture) was separated from Tongliang County. Hezhou only governed Tongliang and Dingyuan counties. In the sixth year of Emperor Yongzheng of the Qing Dynasty (1728), Hezhou became a single state, no longer under the jurisdiction of a county, but under the jurisdiction of Chongqing Prefecture. It governs Mingyueli, Yongqingli, Laisuli and Xingrenli *** 73 towns in 4 li. In the second year of the Republic of China (1913), Hezhou was renamed Hechuan County and belonged to Sichuan East Road. On December 3, 1949, Hechuan was liberated. In April 1952, Hechuan City (exclusive municipality) was added to Chengguan District of Hechuan County, which belongs to Sichuan Province. In January 1958, with the approval of the State Council, the establishment of Hechuan City was cancelled, and the area under the original jurisdiction of Hechuan City was changed to Chengguan Town, Hechuan County. On August 4, 1992, with the approval of the State Council, Hechuan County was abolished and Hechuan City was established, under the jurisdiction of Chongqing City, Sichuan Province. On June 26, 2000, the Chongqing Municipal People's Government (Yufu [2000] No. 131) approved the relocation of the Hechuan Municipal People's Government from No. 31 Sujia Street, Heyang City to Zhongnan Village, Nanjin Street. On October 22, 2006, the State Council (Guohan [2006] No. 110) approved: Hechuan City was abolished and Hechuan District of Chongqing was established. The original administrative area of ??Hechuan City is the administrative area of ??Hechuan District, and the Hechuan District People's Government is located in Nanjin Street. On December 31, 2009, the Chongqing Municipal People's Government (Yu Fu [2009] No. 199) approved the adjustment of some administrative divisions in Hechuan: Dashi Town, Yunmen Town, Caojie Town, and Yanjing Town were abolished, and Dashi Street and Yunmen Town were established. Street, Cao Street, Yanjing Street. At the same time, the administrative divisions of Gulou Town and Sanmiao Town were adjusted.

Animal and plant resources

The vegetation in Hechuan District belongs to the humid evergreen broad-leaved forest subzone in the eastern Sichuan Basin, the hilly and low-mountain vegetation area at the bottom of the basin, and the hilly vegetation area in the Fangshan Mountains in central Sichuan. Its basic types include broad-leaved forest, coniferous forest, bamboo forest and shrub 4 groups, 5 groups and 13 groups. Although there are many types of vegetation, the natural combination is relatively simple. The distribution situation is: Huaying Mountain Area is mainly composed of pure forests of Masson pine, secondary shrubs and subtropical low-mountain grass tussocks; the rest of the area is dominated by cypress and sparse residual forests, and the rest are scattered eucalyptus and bamboo forests, as well as major vegetation. After the destruction, the grasses composed of yellow wattle, horse mulberry, batata, and thatched grass and economic trees such as tung trees, fruit trees, and mulberry trees were formed. Preliminary survey: There are 16 species and 106 varieties of food crops in 5 families, 31 varieties of oil crops in 5 families, 24 varieties of sugar crops in 2 families, 3 species of tea in 1 family, 50 species and 103 varieties of fruit trees in 19 families, and 60 varieties of mulberry trees in 1 family. , there are 44 varieties of vegetables in 13 families, 3 species of hemp in 3 families, 4 species of tobacco in 1 family, 145 species of medicinal materials and wild plants in 67 families, common forest resources include 128 species of woody plants in 54 families, 17 species of herbs in 10 families, bamboo 11 species in 1 family.

The animals raised include 6 species of silkworms in 1 family, 13 species in 4 families of pigs, cattle, sheep and rabbits, 1 species in 4 families of chickens, ducks, geese and bees, and 59 species in 12 families of fish.

Water resources

Boundary water resources consist of three major parts: surface water, transit water and groundwater. Surface water is mainly formed by rainfall. The annual average annual rainfall is 906 million cubic meters. The Huaying Mountains in the east have abundant rainfall, while the high hills and terraces in the west have less rainfall. Rainfall is concentrated in summer, with rainfall from June to September accounting for 54.66% of the annual total. Calculated based on runoff depth, the surface water resources are 637 cubic meters per person, 263 cubic meters per mu, and 729 cubic meters per mu. The transit water is mainly formed by the Jialing River, Fujiang River and Qujiang River that pass through the border.

The multi-year average annual flow of Sanjiang is 73 billion cubic meters, with the highest being 130.185 billion cubic meters and the lowest being 23.029 billion cubic meters. Sanjiang water temperature is 7.1~29.5℃, water quality indicators: ph value is between 7.5~8.2, dissolved oxygen is 6.3~11.94 ml/L, and total hardness is 5.3~99.18 degrees. The total annual groundwater reserves are 107.44 million cubic meters, of which the reserves in Huaying Mountain District account for 65.8% and the remaining areas account for 34.2%. Water resources development and utilization: First, water use by various departments. According to surveys and statistical data from relevant departments in 1993, agricultural irrigation water (including transit water and groundwater, the same below) was 106.5348 million cubic meters, urban domestic and sanitation water was 9.2973 million cubic meters, industrial water was 11.266 million cubic meters, and drinking water for rural people and livestock was 106.5348 million cubic meters. 27.3016 million cubic meters, and hydropower stations use 817.91 million cubic meters of water for power generation. The second is hydropower. The theoretical reserves of hydropower in the Jia, Fuji and Qu rivers for power generation are 562,500 kilowatts. Currently, only 30,000 kilowatts are being developed and utilized by the Fujiang and Weituo power stations. The Fujiang Fujinba Navigation and Power Hub, with a total investment of 760 million yuan, started construction on November 28, 2003. It was constructed according to Level 5 navigation standards. The waterway and locks are Level V. The total installed capacity is 60,000 kilowatts. It is powered by three bulb-type cross-currents. It is composed of generator sets, each unit is 20,000 kilowatts. The Caojie Aviation and Electricity Hub project was launched in December 2004, with a total investment of 4.903 billion yuan and an installed capacity of 500,000 kilowatts. A three-level ship lock will be built and can channelize 70 kilometers of the Jialing River, 88 kilometers of the Qujiang River, 22 kilometers of the Fujiang River, and 180 kilometers of the Yangtze River. The completion of the Jialingjiang Caojie Navigation and Power Hub will effectively change the shipping capacity and flood control capabilities of Sanjiang. 1,000-ton giant ships can also sail directly from Chongqing to Hechuan.

Edit this paragraph 6. Transportation hub

Hechuan has the advantage of being able to navigate the three rivers. It has the convenience of 212 National Highway, Yuhe, Yuwu Expressway and Suiyu Express Railway, and its transportation enjoys natural With the help of others, you will get the blessing of artificial intelligence. At present, Hechuan is focusing on building a transportation hub in northern Chongqing and opening up many convenient passages in Hechuan.

Yuhe (Wu/Nan) Expressway

Chongqing (Wu/Nan) Expressway starts from Yujiawan, Northern New District, Chongqing, and ends at the north of Fujiang Second Bridge in Hechuan City Qiaotou is connected to the Hechuan-Sichuan Expressway, with a total length of 58.83 kilometers and a total investment of 3.1 billion yuan. The road was fully constructed in June 1999. It passes through Huaying Mountain and crosses the Jialing River. The less than 60 kilometers of the road are densely covered with 3 cross-river bridges, 29 bridges of various types and 5 tunnels. The total length of tunnels and bridges exceeds 18 kilometers, accounting for 10% of the line. The density of bridges and tunnels currently accounts for 31% of the total length, ranking first among Chongqing’s open expressways. High-quality road and bridge facilities, advanced management and monitoring levels and green landscapes along the route make it the most modern expressway in Chongqing. After the road is opened to traffic, it will form the main skeleton highway network together with the city's existing expressways, fully realizing Chongqing's strategic vision of "leaving Shanghai in the east, Zhanjiang in the south, Chengdu in the west, and Nanchong in the north".

Sui-Chongqing Express Railway

Sui-Chongqing Express Railway is a national first-class railway trunk line and part of the Chengdu-Chongqing High-speed Railway. It has a total length of 128 kilometers and a total investment of 4.952 billion yuan, of which Hechuan The section is 49.5 kilometers long, with a total investment of 2 billion yuan. Its official operation has shortened the railway mileage between Chengdu and Chongqing by more than 160 kilometers, forming another fast channel between Chengdu and Chongqing, completely changing the traffic constraints on Hechuan, and affecting Hechuan's economic development, labor export, and Employment has a huge pulling effect.

Lanzhou-Chongqing Railway

The Lanzhou-Chongqing Railway has a total length of 820 kilometers, including 57 kilometers in the Hechuan section, with a speed of 200 kilometers per hour. The project's designed transportation capacity can reach 50 million tons of freight per year and 50 passenger cars. For /day, it can meet the long-term passenger and cargo transportation requirements between Lanzhou and Chongqing. It is planned to start construction in the second half of 2008, with a construction period of four years and a total investment of 78.9 billion yuan. According to preliminary estimates, by 2020, the annual cargo of grain, food, coal, cement and other goods that need to be transported by the Lanzhou-Chongqing Railway in the main urban area of ??Hechuan alone will exceed 10 million tons, and the number of passengers will reach 1.26 million. Such a large-scale labor export and material import and export , will definitely bring huge benefits to Lanzhou-Chongqing railway transportation, and will also bring unprecedented development opportunities to Hechuan.

The construction of waterways in Hechuan is also in full swing. Water transportation construction projects such as the Caojie Navigation and Power Hub on the Jialing River, the Fujinba Navigation and Power Hub on the Fujiang River, and docks are gradually turning from blueprints into reality. The construction of these projects will realize the channelization of 300 kilometers of waterways in the three rivers of Hechuan. The 1,000-ton fleet can directly reach Guangyuan City, Sichuan Province via Hechuan, realizing direct transportation between rivers and seas. The highway construction in Hechuan focuses on improving the depth of access, traffic capacity and network connectivity, forming a highway network with highways as the leading and "one vertical, four horizontal and eight trunk lines" highways as the skeleton, criss-crossing and combining trunks and branches. Railways, waterways, and highways go hand in hand, eventually forming a water and land transportation hub from Chongqing to northern Sichuan, Shaanxi, Gansu and other places, creating and enhancing Chongqing's external radiation.

The highways were converted from white to black.

The highways were converted from white to black and Chongqing launched the "white to black" plan in 2007. Most of the highways were changed from cement pavements to asphalt pavements, reducing the number of roads. To prevent environmental pollution, this policy continues to this day. .

Hechuan Viaduct

Hechuan Viaduct The construction of Hechuan Viaduct started in September 2008 and was completed in August 2009. It took nearly a year to greatly improve the road congestion situation.

Edit this paragraph 7. Humanistic accumulation

Hechuan’s humanities have evolved from generation to generation, and many celebrities and important events have spread far and wide at home and abroad. In the battle of "Diaoyu City" in Hechuan during the Song and Yuan Dynasties, the soldiers and civilians of Hezhou fought bloody battles for 36 years, and achieved a great record of repelling the overwhelming Mongolian (Yuan) army and killing Meng Ge, creating a miracle in the history of world war. Therefore, the ancient Diaoyu City is known as "The place where God broke his whip" and "Oriental Mecca City"; the city has a provincial cultural relic protection unit and the most complete ancient Wengcheng ruins in Laitan Town in the country. The Erfo Temple in the town preserves the largest group of Zen stone carvings and rock statues in the country. It is a cultural resort of Zen Buddhism; the Northern Song Dynasty Neo-Confucian Zhou Dunyi served as the judge of Hezhou for 6 years, opened the Hezhou Neo-Confucian school, and wrote an important chapter "Yangxin Pavilion Theory"; in the early Qing Dynasty, Jackie Chan served as the magistrate of Hezhou and worked diligently for the people. , worked hard to govern, and was praised by Emperor Kangxi as "the number one honest official"; historian Zhang Senkai founded the "Sichuan Sericulture Commune" in Taihe Town, Hechuan, and was known as the father of sericulture in eastern Sichuan; Mr. Tao Xingzhi, the great people's educator, founded the "Sichuan Sericulture Commune" in Hechuan Yucai School was founded in the street. Famous experts and scholars such as Jian Bozan, He Luting, Dai Ailian, etc. once taught here. Li Peng, the former chairman of the Standing Committee of the National People's Congress, also studied at Yucai School when he was a child; Lu Zuofu, one of the four major industrialists in my country, He founded the Minsheng Industrial Company in Hechuan and became the king of modern Chinese shipping. During the Anti-Japanese War, the rush to transport supplies to Sichuan was called the "Dunkirk of Chinese industry" and saved the country's industrial lifeline; the older generation of proletarian revolutionaries Zhao Juntao once He founded a wartime child care center in Tuchang; Liu Wenxue, the first young hero of New China, heroically sacrificed his life to protect collective property and became a model for the generation. Proletarian revolutionaries such as Zhou Enlai and Chen Yi also left glorious footprints in Hechuan. Since the founding of New China, outstanding figures such as Liu Peng, Director of the State Sports General Administration, Xie Xiaojun, Vice Mayor of Chongqing, Shi Qingyun, Academician of the Chinese Academy of Sciences, Li Xiaohong, President of Wuhan University, and Wu Yajun, Chairman of Longfor Real Estate, have emerged.
