Xiangjiang River system is located in the south of the Yangtze River and north of Nanling. Luo Xiao Mountain and Ganjiang River system are in the east, and Hengshan Mountain is adjacent to Zishui in the west. The main tributaries of Xiangjiang River, Xiaoshui, Fuling, Leishui, Weishui, Suishui and Liuyang River, flow into the main stream from the east coast, while the tributaries, Qi Shui, Steamed Water, Juanshui, Lianshui and Suishui, flow into the main stream from the west coast. Xiangjiang river basin is mostly undulating hills, valley plains and basins, and the alluvial plain below Changsha in the lower reaches is larger, which is connected with the estuary plains of Zijiang, Yuanjiang and Lishui, and is the largest lakeside plain in the province.
There is little difference in elevation between the upstream and downstream of Xiangjiang River Basin, but it is uneven, which accelerates rainwater collection. The upstream of each tributary winds in the mountains, showing the characteristics of mountain streams and rivers. Xiangjiang River is called the upper reaches above Yongzhou, and the current is swift. Sometimes, rivers pass through cut rocks and form canyons. Limestone is widely distributed in the basin, with many karst caves and large groundwater recharge river flow. Xiangjiang River is the middle reaches between Yongzhou and Hengyang, with undulating mountains along the coast and scattered basins and canyons. Xiangjiang River is downstream of Hengshan Mountain, with flat terrain, stable rivers and intermittent sandbars along the river. There are lakes of different sizes scattered at the mouth of Xiangjiang River, most of which are the remains of Dongting Lake in the past.
