Where does Liaohe River enter the sea?

Liaohe River is the largest river in the southeast of China and one of the seven rivers in China. Originated in Pingquan County, Hebei Province, it flows through Hebei, Inner Mongolia, Jilin and Liaoning provinces and joins the Bohai Sea in Panshan County, Liaoning Province. With a total length of 1430 km and a drainage area of 229,000 square kilometers, it is one of the cradles of Chinese nation and civilization. Overview of Liao River Liao River is called the "mother river" of Liaoning people. Geographical location is between east longitude 1 17 00' and north latitude 125 30' and north latitude 40 30' and north latitude 45 10' ... bordering Bohai Sea and Yellow Sea in the south, Inner Mongolia inland river and Hebei Hailuan River basin in the southwest, and Songhua River basin in the north. Liao River was called Julie in ancient times, Da Liao River in Han Dynasty, Liao River after Five Dynasties and Liu Ju in Qing Dynasty. Liaohe River Basin spans Hebei, Inner Mongolia, Jilin and Liaoning provinces. Shangyuan (AD), that is, Laoha River, originated in Guangtou Mountain, seven old Mountain Range, Pingquan County, Hebei Province (elevation 1729 meters). It flows northeast near Dayushu via Naxi Lamulun River, bordering Zhaowu Damon (Chifeng City) and Zhelimumeng (Tongliao City) in Inner Mongolia Autonomous Region, then flows eastward to Jilin Province, turns south, and is later called Liaohe River. The tributaries of Liaohe River include Tai Su River, Qinghe River, Chaihe River, Fanhe River and Liuhe River. , originally in taian county branch for six rooms, a west flow, called Shuangtaizi River. Narao Yanghe River flows into Liaodong Bay, Panshan County, Panjin City, and there are artificial channels connecting with Raoyang River in the nearby waters. The other flows south, called Wailiao River, Nahun River and Taizi River, and then called Daliao River, and Shangkou empties into Liaodong Bay. 1958 The outer Liaohe River is blocked near Liujianfang, so that the Liaohe River enters the sea from Shuangtaizi River, and the Hunhe River and Taizi River enter the sea from Daliao River.

The upper reaches of Liaohe River are divided into east branch and west branch. Dongliao River originated near Hadaling, Liaoyuan City, Jilin Province. The water flows out of the cave and enters the Sanjiangkou Liaoning Province through the eastern mountainous hills, with a total length of 383 kilometers. There are two sources of Xiliaohe River: one comes from Guangtouling, Pingquan County, Hebei Province, and flows into Ningcheng County, Inner Mongolia Autonomous Region, which is called Laoha River, with a total length of 873 kilometers; The other source comes from Baicha Mountain in Keshiketeng Banner, Inner Mongolia, which is called Xilamulun River, with a total length of 380 kilometers. Laoha River and Xilamulun River meet at Sujiabao in Zhelimu League, which is called Xiliaohe River. Xiliaohe River is 449 kilometers long and flows from east to south in Shuangliao County, Jilin Province. Fudian, Changtu County, Liaoning Province, is called Liaohe River after it joins the Dongliao River. The total length of the main stream of Liaohe River is 5 12km, which runs through Liaohe Plain from northeast to southwest. The plain is composed of deep river alluvium, with flat terrain and occasional swamp distribution. Liaohe River system includes Liaohe River, Hunhe River, Taizi River and Raoyang River, with a total basin area of 229,400 square kilometers. After Liujianfang 1958 in Panshan County blocked the outer Liaohe River, the Liaohe River basin was divided into two independent water systems: Liaohe River and Raoyang River merged into the sea in Panshan County, and Hunhe River and Taizi River merged into the sea in Yingkou City via Daliao River. The precipitation in Liaohe river basin is concentrated in 6? 6? In May, the water quantity changed greatly and the sediment concentration was high. Floods have often occurred in history. Rivers freeze for three months every year. Small ships can be traced back to Sanjiangkou. Dahuofang Reservoir was built on the Hunhe River to control flood disasters.

Liaohe River has two sources. Dongyuan is called Dongliao River, which originates from the northwest foot of Hadaling in the southeast of Jilin Province, flows northward through Liaoyuan City, passes through Erlongshan Reservoir, and meets Xiyuan in Fudian, Changtu County, Liaoning Province, and is called Xiliao River. The total area of Liaohe River Basin is 210.9 million square kilometers, and the river length is10.390 kilometers. According to the data of Hekou Control Station 1956 ~ 1979, the average annual discharge of Liaohe River is about 400 cubic meters per second, the average annual runoff is 65.438+026 billion cubic meters, and the average annual sediment discharge is 20.98 million tons. Natural drop of main stream 1200m.

Liaohe River system has 29 main tributaries, with a drainage area of over 65,438+000 km. Almost all the water systems in Liaohe River Basin are controlled by reservoirs, and the water level fluctuates greatly. The coastal areas of the basin are mostly arid desert hills, with serious soil erosion and shallow riverbed siltation, showing the characteristics of "drought and dryness, heavy rain overflowing". From late May to mid-September, the average daily water temperature is generally above 20℃, which is the peak season for fish growth. 10 The ice age is from mid-October to early April of the following year, and the ice thickness is 60 ~ 90 cm.

Xiliaohe is divided into two tributaries, the main stream of Xiliaohe in the south and Xinkai River in the north. The second river flows south after the confluence of Shuangliao River and is called Liaohe River after the confluence of Fudian River and Dongliao River. After passing Tieling, turn southwest, and then divide into two parts in six rooms. A south stream is Wailiao River, which joins Hunhe River and Taizi River at Sancha River and is called Daliao River, and flows into Bohai Sea through Yingkou City. Another southwest stream is called Shuangtaizi River, which bypasses Yanghe River at the southern foot of Panshan Mountain and then flows into Bohai Sea. After 1958, six houses in taian county blocked the external Liaohe River, making Hunhe River and Taizi River independent water systems, and the main stream of Liaohe River changed from Panshan County in Panjin City to the sea. The upper reaches of Liaohe River flows through the loess hills, joins Kundu River, Jinying River, Beng River and Yangchangzi River, and then flows into the plain below 400 meters above sea level, reaching Changtufudian, with a total length of 882 kilometers. After receiving Jiaolai River, a tributary of the south bank, the water level of Xiliaohe River dropped below 300 meters, crossed the low hills in northern Liaoning to the south, accepted Zhaosutai River, Qinghe River, Chaihe River and Fanhe River, entered the plain below 50 meters above sea level, and reached Shifo Temple as the middle reaches of Liaohe River, with a total length of 2 10 km. The downstream flows through the alluvial plain, and the north bank flows into Xiushui River, Yangximu River and Liuhe River. It is 302 kilometers long at the mouth of Shuangtaizi River. Water System The Liaohe River is a dendritic water system, which is wide from east to west and narrow from north to south. It consists of two water systems: one is the East and West Liao River, and the main stream of Liao River flows into the sea from Panjin via Shuangtaizi River, with a length of 516 km; The other is Hunhe River and Taizi River, which meet at Sancha River and then enter the sea from Yingkou via Daliao River, with a total length of 94 kilometers.
