Which area in Liaocheng is the most economically backward?

Liaocheng City is located in the economically developed Shandong Province, in the west of Shandong, adjacent to Henan and Hebei, and at the junction of the three administrative regions of East China, North China, and Central China. The Beijing-Hangzhou Grand Canal, which represents China's commercial civilization, and the Yellow River, which represents agricultural civilization, intersect here. The Beijing-Kowloon Railway, which runs through the north and south of China, and the Jiaoji-Han Railway and Expressway, which connect the east and west of the motherland, intersect here to form the "Golden Cross". Liaocheng not only plays a central role in radiating and driving the economic development of western Shandong, but is also an important channel for economic, technological and cultural exchanges with inland provinces such as Shanxi and Hebei. Liaocheng can not only make use of the advanced technology of the eastern coast, but also the rich resources of the eastern provinces. It is an important transportation hub, energy base, inland port in China and a central city radiating the junction of Hebei, Shandong and Henan.

Liaocheng City is located between 35°47’～37°02’ north latitude and 115°16’～116°32’ east longitude, with a direct distance of 138 kilometers from north to south and 114 kilometers from east to west.

Liaocheng has a long history and splendid culture. As early as primitive society, there were ancestors living here and engaging in agricultural production. Eight Longshan cultural cities dating back about six to seven thousand years have been discovered in the city. They are the largest Longshan cultural cities discovered in the country so far. It can be seen that the west bank of the ancient Jishui River was an extremely important political and cultural center at that time. During the Xia, Shang and Zhou dynasties, Liaocheng's economy and society developed rapidly, and agriculture and handicrafts were relatively developed; during the Spring and Autumn Period, Liaocheng was an important city in the west of Qi State; during the Warring States Period, Liaocheng was a place where princes fought; during the Qin and Han Dynasties, the economy and culture developed rapidly , people's living standards have been greatly improved. Copper, iron, and aluminum are the main production tools. Water wells are used to solve drinking water and irrigation problems. Rich families travel by carriage and horse. Bronze mirrors and smokers have become necessities. Pottery with a high level of craftsmanship can be made. , cultural and educational undertakings developed rapidly, and many famous scholars and generals were cultivated; during the Three Kingdoms, Two Jin Dynasties, and Southern and Northern Dynasties, wars were frequent and there were many natural disasters. During the period of partial unification, society was relatively stable, and economic and cultural undertakings recovered and developed to a certain extent. In the 4th year of Sui Dynasty (AD 608), Emperor Yang of the Sui Dynasty dug the Beijing-Hangzhou Grand Canal, which facilitated transportation and water conservancy in the city and promoted economic and cultural development. At that time, Linqing was an important transportation hub. The Tang Dynasty was a period of comprehensive development of the city's politics, economy, and culture, especially the development of education, which produced many celebrities; the Ming and Qing dynasties were glorious periods in the history of Liaocheng, from the 26th year of the Yuan Dynasty (1289) to the Ming Dynasty In the ninth year of Yongle (1411), several construction projects were started to open up the river. The Grand Canal, which runs through the north and south of China, brought vitality to the development and prosperity of Liaocheng. One of the big commercial ports. In Liaocheng, "there are no less than 100,000 households facing each other with the fireworks of the city", merchants gathered together, all industries were prosperous, sails and rafts were like forests, boats and boats were connected with each other, carriages and horses were flowing in, and goods were piled up like mountains. The foreign merchants' guild hall stands beside the river, with lofty towers, pavilions, palaces and famous temples. Emperor Kangxi of the Qing Dynasty came to chat four times, and Emperor Qianlong stayed in Liaocheng nine times. The city has prosperous commerce and agriculture, textile industry, printing industry, pen industry, handicraft production industry, brick kiln industry, food industry, shipbuilding industry, and water transportation industry. Before the founding of the Republic of China, there were members of the Tongmenghui in the city who secretly organized people to carry out reforms. During the Republic of China, Liaocheng was the political, cultural and center of Western Shandong. At the beginning of the Republic of China, there were cotton industry research institutes, workshops, and experimental factories, roads were built, and automobile transportation companies, electric lighting companies, banks, weaving factories, hospitals, government middle schools, and normal schools were established. In the middle and late period of the Republic of China, due to warlords' melee and Japanese invasion, agriculture, industry and commerce suffered great damage. After the "July 7th Incident" in 1937, Liaocheng became the forefront of the anti-Japanese war.

Edit this paragraph of myths and legends

Liaocheng is also known as the "Phoenix City" because the location and layout of the ancient city pool in Liaocheng resembles a phoenix, so it is known as the "Phoenix City". There is also a legend about this:

Legend has it that the Liaocheng area was originally a sycamore forest, where a pair of phoenixes lived, commanding all the birds in the forest and living a happy life. One year there was a flood, and an evil dragon from the East China Sea came here and drove away the phoenix, turning the area into a vast ocean. People called it Dongzhou Lake. Seeing the rippling waves of the lake, the lush forests and flowers, and the beautiful scenery, the local officials wanted to build a city by the lake. However, the craftsmen felt that the project was difficult and did not dare to undertake it. At this time, two people came, one named Wang Dong and the other Wang Chang, who volunteered to undertake the construction. It turns out that these two people are the sons of the pair of phoenixes who were driven away by the evil dragon. When Wang Dong and Wang Chang built the city, Phoenix led hundreds of birds to bring wood and stone materials. Soon, a majestic lake city was built. In order to commemorate Phoenix's achievements in building the city, people named the city Phoenix City. Later, the evil dragon of the East China Sea made trouble again and attempted to destroy the new city. At this time, Wang Dong and Wang Chang fought against the evil dragon. The evil dragon fled to the East China Sea, dug out a water channel, and diverted sea water to flood the city. In order to save the people of Phoenix City, brothers Wang Dong and Wang Chang got into the water and blocked the waterway with their bodies. In order to thank the two brothers for their noble character of protecting the city and saving the people, people changed the name of Phoenix City to Dongchang City.

Edit this paragraph's physical geography

The terrain within the territory is relatively gentle. Except for the 10 denuded residual mountains along the Yellow River in Dong'e County, they are all Yellow River alluvial plains. The terrain gradually slopes from southwest to northeast. The southwest of Shen County is the highest, with an altitude of 49 meters; the northeast of Gaotang County is the lowest, with an altitude of 27.5 meters. Because the Yellow River changed its course many times in Liaocheng and flooded in history, it formed an undulating micro-topography with alternating high slopes and depressions.

Structure

The city’s geological structure is part of the North China Platform (I). The Liaokao Fault Zone divides the city into two secondary structural units, with the Liaoji Platform in the west syncline (II1), and the Luxitai anticline (II2) in the east. There are two third-level structural units in the Liaoji platform syncline, namely the Linqing Au fault area (Ⅲ1) and the Neihuanglong fault area (Ⅲ2); there is one third-level structural unit in the Luxi platform anticline, namely the Chiping Au Break zone (III3). Secondly, it is divided into seven fourth-level structural units from west to east: Guantao uplift area (IV1), Linqing depression area (IV2), Xinji uplift area (IV3), Shenxian depression area (IV4), Sang'a depression area Uplift area (Ⅳ5), Yanggu uplift area (IV6), Dong'a depression area (IV7). There are many faults distributed in the area, and their trend is generally northeast. The larger fault is the Liakao fault, followed by the Guanguang fault, Guanxian fault, Tangyi fault, Liaocheng fault, Chiping fault, Dong'a fault, Guantao fault, Maling fault, and there are many smaller faults. The Liaokao fault stretches from Chiping in the north to Lankao, Henan in the south, with a total length of 270 kilometers and a length in the city of 110 kilometers. It is the dividing line between the Liaoji Tai syncline and the Luxi Tai anticline in the city, and also controls the Tertiary system in the city. development and structural morphology. The Guan-Guang fault starts from Guanxian in the west, passes through the Liaokao fault, and reaches Guangrao in the east, with a total length of 290 kilometers, and the length of the city is about 100 kilometers.

The northern wall of this fault descends and the southern wall rises. The Guanxian Fault stretches from Linqing Shitao in the north to Liangtang in Guanxian County in the south, intersecting with the Guanguang Fault, with a total length of about 60 kilometers. Its northern end is the dividing line between the Linqing Sag and the Xinji Uplift, and its southern end is the Linqing Sag. The dividing line with the Sang'a bulge. The Tangyi fault extends northwest from Dongduzhuang, Shen County, passes through Tangyi, and ends at the intersection of Boping and Liakao faults. The total length is about 73 kilometers, and its southern plate is a descending plate. The Liaocheng fault meets the Liaocheng and Liakao faults in the northeast and the Hedian and Tangyi faults in Shenxian County in the southwest. The total length is about 40 kilometers. It is a fault with a descending plate in the north. The Chiping fault is a fault that descends in the east wall. It stretches from Chiping Wanglao in the north to Yanggu Qiqi in the south, and the whole city is about 55 kilometers away. The Dong'a fault is located in the easternmost part of the city and is a fault that descends from the west plate. It stretches from Donggaoji in the north to Zhangqiu in Yanggu in the south, with a total length of about 50 kilometers. The Guantao Fault is located in the westernmost part of the city. This fault divides the North Guantao structure into two, bringing the Kongdian Formation strata on both sides of the fault zone into contact with the Ordovician limestone. The Maling fault runs northwest, with a total length of about 15 kilometers, and a descending plate in the northeast. This fault zone is the dividing line between the Linqing Depression and the Neihuang Uplift in Henan.

Stratigraphy

Since the late Tertiary, it has generally accepted the deposition of the Upper Tertiary and Quaternary systems, mainly the Yellow River flood impact and alluvial deposits, except for the East Ayan The 10 solitary mountains less than 50 meters high in the Yellow River area have exposures of Paleozoic Ordovician limestone, and the rest are covered by the Quaternary Series of the Cenozoic. The thickness of the Quaternary System is generally 30 to 270 meters, with the thicker areas in Linqing, Shenxian, and Gaotang. The fourth system includes the Pleistocene and the Pleistocene, and the Pleistocene is divided into upper, middle and lower Pleistocene. The Holocene is mainly alluvial and diluvial sediments, with a thickness of 7 to 25 meters, and is widely distributed throughout the city; the Pleistocene is mainly fluvial and lacustrine sediments, with a thickness of 30 to 260 meters. Below the Quaternary Series are the Minghuazhen Formation and Guantao Formation of the Upper Tertiary Series; the Dongying Formation, Shahejie Formation, and Kongdian Formation of the Lower Tertiary Series; the Paleozoic Carboniferous Permian, Ordovician, Cambrian, and other There are Paleozoic metamorphic rocks, etc.
