Where is the source of Rongjiang River? It comes from the mouth of Jiang Xun River in Sanjiang County, Guangxi.

The source of Rongjiang River is the mouth of Jiang Xun River in Sanjiang County, Guangxi, and ends at the mouth of Longjiang River in Liucheng County. Rongjiang, also known as Rongjiang and Tanjiang, belongs to the Pearl River Basin. There are many Rongjiang characters in the counties where Rongjiang flows, including Rongshui County and Rongan County. In Rong 'an County, the total length of Rongjiang River is about 35 kilometers, and the river width is between 350 meters and 440 meters.

I. Introduction of Rongjiang Water Flow Rongjiang entered Rongan County from Rongshui County and entered Rongshui County after flowing through several towns. The length of rivers in Rongshui County is 68km, with the highest water level of about118m and the lowest water level of about105m. The distribution of four seasons is still quite small, and the water level of many rivers rises linearly in summer.

The bottom of Rongjiang River is mostly composed of pebbles and sand, and the sediment concentration is still relatively high. The length of the river in Danzhou section of Sanjiang County is about 44 kilometers, and the annual runoff is/kloc-0.79 billion cubic meters. Rongjiang in Sanjiang County is also known as Huaishui and Jiang Xun.

The annual flow of Rongjiang River in Liucheng County is more than 20 billion cubic meters, and the drainage area is more than 20,000 square kilometers. The height difference in Liucheng County is about12m, which is still relatively small, and the sediment concentration is only 1%. In Liucheng County, the water level of Rongjiang River was the highest in May, and the sediment concentration also increased significantly.

2. Changes in the area near Rongjiang River There are many sandbars in Sanjiang County. In Xizhou, there are about 100 families here, which is the origin of fruit trees in the county. This place is very famous locally. Agriculture was the main industry at that time. Later, factories and power stations were built in Xizhou, and the residents living here were forced to move to other places.

1974, grain was so important that all the fruit trees planted in Xizhou were cut down and turned into rice fields, and local agriculture began to retrogress. Five years later, I found that this practice was not very correct, so I changed my previous route, started the policy of returning farmland to forests, and started planting fruit trees again.
