There are two big rivers in the desert. One is Ceyuan River, which originated from Hongshui River in Ceyuan Township, Yanling County. The source is Shennong Peak, the highest peak in Hunan Province, also known as Maofeng. After going down to Shandong, Big Bird, Ceyuan and Jiangcun, there is another big river-Shuikou River (originating from the junction of Wuzeng and Hunan in Tianxin Village, Xiacun Town, Yanling County), which is called river desert water. Rivers and desert water pass through Muwan, Jiangzhou is located in Nakanping River, Wulipai, Xiayang Town, Yanling County, and Xielaishui is located in Xitai Village, Sanhe Town, Yanling County. The river desert basin covers an area of 904 square kilometers and the main stream is 88 kilometers long. Because the river in the desert is longer than that in Shesethi, and the basin area is larger.
In the spring of 20 1 1, according to the principle of only reaching Heyuan, the flood river in Ceyuan Township of Yanling County was initially determined as the positive source of backwater. After detailed field survey, at 20 1 1, 1 1, the first water conservancy survey group determined that Shuikou River was the positive source of backwater. In 201112, the Heyuan exploration team headed for the junction of Hunan and Jiangxi along Nanyuan, and exhausted the water source at the altitude of 1580 meters, that is, measured the latitude and longitude coordinates, and determined the Xia 'anxia valley at the junction of Dalingbei Formation and Yingpanxu in Tianxin Village, suichuan county, Jiangxi Province as the positive source of backwater. It can be inferred that the longitude and latitude of the focal point are about 26.25 north latitude and 1 13.99 east longitude.
Jishui is a tributary of the lower reaches of Xiangjiang River. Originated in Bamian Mountain in the south of Yanling County, it flows through Chaling County and Youxian County in the northwest and flows into Xiangjiang River in Xintang Town of Hengdong County. The total length is 296 kilometers, and the drainage area is 10505 square kilometers. "Notes on Water Classics" records: "Shui Gu leaves Shangxiang, Chaling County, and the northwest passes through the west of the county. ..... and pass through the south of Jixian County in the northwest. " Weishui entered Youxian County from Renqiao in Caihuaping Town via Chaling County, and entered Hengdong County in Lijiadawu in Caihuaping Town. In Youxian County, the main stream of Jishui River is 29.5 kilometers long, including Youshui River, Zhuojiang River and Yongle River, and the basin area of Jishui River in the county is 1929.6438+0 square kilometers.
The upper reaches of Shui Gu are fast-flowing and the rivers are relatively narrow. Entering the territory of Youxian County, the slope drops slightly, the water flow increases, and the river surface is wider. Based on this, in the Five Dynasties (907 ~ 923), the county magistrate of Youxian moved from the east to the vicinity of Weishui. Youxian county used to be an important water transport town, not only Youxian county, but also a distribution center for materials in Chaling and Lingxian counties. The upstream ship carries the goods to the big ship here, and the upstream raft and bamboo raft gather here to form a big raft. By the end of the Qing Dynasty and the Republic of China, there were three water transport terminals in Youxian County: Tan Jia, Xuemen and Tongren Palace. Sail and sail, fight for the flow; Ships and telephone poles moored on the dock are like forests, and people are buzzing; People come and go on the river bank, cars come and go, and freight keeps going.
