- Abstract:
- Taking the comprehensive evaluation of the water resources carrying capacity of the Yangtze River economic belt as the center, we constructed the comprehensive evaluation index system of water resources carrying capacity through water resources, society, economy and ecology. The dynamic changes and regional differences of water resources carrying capacity in 11 provinces and cities of the Yangtze River Economic Belt in 2007-2016 were calculated by using TOPSIS method. The ArcGIS 10.2 software was used to visualize the calculation results of carrying capacity of water resources in various provinces and cities in the Yangtze River Economic Belt in 2007 and 2016. The results showed that in 2007-2016, the carrying capacity of water resources in the Yangtze River Economic Belt presented the upward trend of fluctuation, and the carrying capacity was basically maintained at the alert and intermediate level; the water resources carrying capacity of the economically developed eastern region was gradually higher than that in the underdeveloped middle and western regions, and the gap was expanding in recent years; the provinces or municipality with average annual growth rates of water resources carrying capacity ranked in the first three among the 11 provinces and cities of the Yangtze River Economic Belt are Guizhou Province, Shanghai, and Yunnan Province. the provinces or municipality with the negative annual average growth rate of water resources carrying capacity are Hubei, Chongqing and Sichuan. In general, the overall level of water resources carrying capacity of the provinces and cities of the Yangtze River Economic Zone was still low, and the balance of water resources carrying capacity was low, and it did not change too much over the time.
