Geographical characteristics of the Yangtze River basin;
1. Huge water system and abundant runoff: the Yangtze River basin has a huge water system, with a total length of about 6,300 kilometers, with a basin area of about 1.8 million square kilometers, accounting for 18.7% of the land area of China. The total annual runoff in the Yangtze River basin is about 995.8 billion cubic meters, accounting for 35% of the total river runoff in China. This makes the Yangtze River basin one of the regions with the richest water resources in China. The water system in the Yangtze River Basin provides important water resources for agriculture, industry and life in China.
2. The terrain is complex and the climate is diverse: the terrain of the Yangtze River Basin is complex and diverse, with the west high and the east low, with a total drop of 5,400 meters from the source of the river to the estuary. The basin includes many landform types such as mountains, plateaus, hills and plains. This complex terrain has brought various climate types to the Yangtze River basin. The upper reaches of the Yangtze River basin have a plateau climate, the middle reaches have a subtropical monsoon climate, and the lower reaches have a subtropical humid climate. This climate diversity provides abundant conditions for the ecological environment and biodiversity in the Yangtze River basin.
3. Abundant resources and fragile ecological environment: The Yangtze River basin is one of the regions with abundant resources in China. There are abundant water resources, hydropower resources, land resources and mineral resources in the basin. In particular, the theoretical reserves of hydropower resources in the Yangtze River basin are as high as 305,000 MW, accounting for 40% of the total hydropower reserves in China. Due to long-term over-exploitation and environmental pollution, the ecological environment in the Yangtze River basin is facing severe challenges. Problems such as soil erosion, water pollution and biodiversity decline are becoming more and more serious.
