Introduction to Dongying, Shandong

Dongying City is where the thousands-mile Yellow River flows into the sea. It is the central city of the Yellow River Delta and the main battlefield and core area of ??the Yellow River Delta's high-efficiency ecological economic zone. The city was established in 1983. At the beginning, the city was divided into three districts: Dongying, Niuzhuang, and Hekou, three counties: Guangrao, Lijin, and Kenli, three towns, 55 people's communes, and 1,780 production brigades. In 1984, the communes were withdrawn and transformed into townships, and the teams were withdrawn and transformed into villages. In June 1987, Niuzhuang District and Dongying District were merged into Dongying District. Since then, the scale of townships and towns has been adjusted many times, and some towns have been withdrawn and merged. By the end of 2007, Dongying City had jurisdiction over 2 districts, Dongying and Hekou, 3 counties, Guangrao, Lijin, and Kenli, 23 towns, 13 townships, 7 sub-district offices, and 1,781 village committees. Guangrao County in the south (Le'an, Qi State) is the hometown of Sun Wu, the great military strategist in ancient times. Shijia Village, Niuzhuang Town, Dongying District is the birthplace of Lu Opera. The Dongying City History Museum (Guangrao) has the earliest Chinese translation of "The Communist Party of China". declaration". To the north is the Yellow River delta, a new alluvial siltation land of the Yellow River. This is the station of Shengli Oilfield, the second largest oil field in China, the Jijun base, and the station of China University of Petroleum (East China). There are abundant oil and natural gas resources here, as well as rich marine resources. The south has a long history and the north is rich in resources. There is Asia's largest above-ground artificial lake - Swan Lake, and the largest urban park in Shandong Province - Dongying Qingfeng Lake Park. Guangrao County in the south is the first county in the country with asphalt roads in every village, the first counties with telephones in every village, the first counties with buses in every village, and the first counties with running water in every village. , is also the first county in Dongying City to enter the top 100 counties in the country. Dongying City is currently undergoing a reconstruction project of the Guangli River, and has proposed the planning concept of "returning to the river", which has three meanings: the Guangli River will return to become an urban river with ecological landscape functions; the central city will return to become a harmonious place closely connected with the river. Relationship; reshape the relationship between people and water - from "request" to "return", let the river become a healthy river, and develop together with the city.

Landform

The terrain slopes from southwest to northeast along the direction of the Yellow River. The highest elevation in the southwest is 28 meters (Dago elevation, the same below), the lowest elevation in the northeast is 1 meter, and the natural ratio drops to 1/8000 to 1/12000; the highest elevation in the west is 11 meters, and the lowest elevation in the east is 1 meter, and the natural ratio Reduced to 1/7000. The Yellow River passes through the country. In the direction away from the river, the height near the river is high and the distance away from the river is low. The natural ratio of the river away from the river is reduced to 1/7000. The river bottom is 2 to 4 meters higher than the land behind the river, forming a "suspended river above the ground." There are 5 types of micro landforms in the city: ancient river beach highlands, accounting for 4.15% of the city's total area, mainly distributed in the upper reaches of the Yellow River breach fan; river beach highlands, accounting for 3.58% of the city's total area, mainly distributed between the Yellow River channel and the levee; Sloping flat land, accounting for 54.54% of the city's total area, is the transition zone between hills and depressions; shallow flat land, accounting for 10.68% of the city's total area, is mainly distributed between the ancient river beach highlands to the south of Xiaoqing River, and to the north of Xiaoqing River. Among the slightly sloping flat land, between the gentle hills and in the low-lying areas of the old Yellow River; beach land, accounting for 27.05% of the city's total area, is distributed in a strip parallel to the coastline.

Climate

Dongying City is located in mid-latitudes, with its back to the land and the sea. It is affected by the Eurasian continent and the western Pacific. It has a warm temperate continental monsoon climate and a mild climate. Four distinct seasons.

Rivers

The Yellow River starts from the Binzhou border on the Dongying section, runs through the entire territory of Dongying City from southwest to northeast, and flows into the Bohai Sea in the northeast of Kenli County, with a total length of 138 kilometers. The runoff of the Yellow River varies greatly between years, is unevenly distributed within the year, and contains large amounts of sediment. According to the measured data of Lijin Hydrological Station from 1950 to 2001, the average annual runoff of the Yellow River is 33.26 billion cubic meters, with a maximum of 97.31 billion cubic meters (1964) and a minimum of 1.88 billion cubic meters (1997); the maximum flow is 10,400 cubic meters per second ( July 1958), the minimum flow is a dry river; the average annual sediment load is 836 million tons, with a maximum of 2.1 billion tons (1958) and a minimum of 15 million tons (1997). Since the 1990s, the annual runoff of the Yellow River has decreased, with frequent outages. After 1999, the Yellow River Water Conservancy Commission intensified the management of water diversion in areas along the Yellow River, and the flow interruption phenomenon slowed down. From 2000 to 2004, continuous flow was achieved.

In 2002, the annual runoff of the Yellow River was 4.158 billion cubic meters; in 2003, the annual runoff of the Yellow River was 19.13 billion cubic meters; in 2004, the annual runoff of the Yellow River was 19.82 billion cubic meters.

The coastline of Dongying City starts from the mouth of Shunjianggou River in the north and ends at the mouth of Zimaigou River in the south, with a total length of 350.34 kilometers, accounting for about 1/9 of the coastline of Shandong Province. The beach area from "0" meters to the shoreline is 101,900 hectares. The shallow sea area within the minus 10-meter isobath is 4,800 square kilometers. The seabed along the coast is relatively flat, with shallow seabed muddy silt accounting for 77.8% and sandy silt accounting for 22.2%. The transparency of sea water is 32 to 55 centimeters. Seawater temperature and salinity are greatly affected by continental climate and Yellow River runoff. There is a three-month glacial period along the coast in winter. The range of seawater ice is 5 to 10 nautical miles, and the salinity is about 30‰. In spring, the seawater temperature is 12-20℃, and the salinity is mostly 22-31‰; in summer, the seawater temperature is 24-28 ℃, and the salinity is 21-30‰; there are low-temperature and low-salt water tongues near the mouth of the Yellow River all year round. The Dongying sea area is semi-enclosed. The tides on most shore sections are irregular semidiurnal tides, which occur twice a day. The daily high and low tide difference is generally 0.2 to 2 meters. Spring tides mostly occur from March to April and July to November. In July, the highest tide level exceeds 5 meters. It is prone to storm surge disasters. In the past century, there have been 7 storm surge disasters with tide levels higher than 3.5 meters. Under the influence of the Yellow River and other rivers, the offshore sea has low salinity, high oxygen content, rich organic matter, and rich bait, which is suitable for feeding, breeding, and migration of various fish and shrimps. After the establishment of the city

In April 1961, the North China Petroleum Exploration Office drilled the first exploration well, Huaba Well, near Dongying Village, Xindian Commune, former Guangrao County, and obtained an industrial oil flow of 8.1 tons per day. From then on, the North China Oil Battle began. On September 23, 1962, Well Ying 2 drilled in the Dongying structure achieved a daily production of 555 tons of oil, making it the oil well with the highest daily production in the country at that time. To commemorate the day when this high-yield oil well was drilled, Shengli Oilfield was first called "923 Factory". With the in-depth development of the oil exploration and development battle, the Dongying Village area gradually formed a mining town composed of the battle headquarters and some secondary units and logistics units, which people called "bases". In March 1965, in order to support the oil campaign, with the approval of the Shandong Provincial Committee of the Communist Party of China, the Huimin Prefectural Committee decided to establish a county-level working organization-the Dongying Working Committee and Dongying Office of the Huimin District of the Chinese Communist Party, and organized a A number of commercial, financial, postal and telecommunications institutions serving the mining area. On June 11, 1971, the 923 Plant was renamed "Shengli Oilfield". In order to meet the needs of the development of Shengli Oilfield and the development and construction of the Yellow River Delta, the Shandong Provincial Government requested instructions from the State Council to establish the provincial prefecture-level city - Dongying City in August 1982. On November 10 of the same year, the State Council issued [82] Guohanzi No. 249 Approved the provincial government's request for instructions, and divided the 2 counties of Kenli and Lijin in the original Huimin area, 4 communes in Guangrao County, 4 communes in Zhanhua County, 1 commune and 3 brigades in Boxing County to establish provincial jurisdiction Level Dongying City. On August 30, 1983, the State Council approved the Shandong Provincial Government's request with [83] Guohanzi Document No. 175 and placed Guangrao County under Dongying City.
