Abstract: In order to discuss the present situation and future trend of water resource carrying capacity in China,In this paper, the index system was constructed from the four aspects of pressure, pressure, coordination and management. The water resource carrying capacity of China from 2000 to 2015 was discussed through the comprehensive evaluation method based on entropy weight method. The characteristics of space time change were analyzed using m-k trend method, and the future trend was predicted by R/S analysis method.The results showed that: China’s deteriorating condition on the whole, the water resources carrying capacity in the north latitude 35°-40° are quite common, north and south on both sides of the area is better. The deterioration of water resources carrying capacity mainly occurred in northeast and southwest regions, while the improvement mainly occurred in southeast and northwest regions without significant changes. In the future, WRCC will continue to deteriorate in most areas of the country, mainly in the Inner Mongolia plateau, qinghai tibet plateau, yunnan guizhou plateau, north China plain, middle and lower Yangtze river plain and southeast coastal areas. Qinghai and hunan are likely to deteriorate; Other areas will show an improvement or likely improvement trend. The bearing potential of the southeast coastal area is large, the places of shanxi, shandong and Beijing are almost exhausted, and the advantages of the northeast and qinghai tibet plateau are gradually lost, so corresponding measures should be taken according to the bearing potential of water resources in different regions. Coordination system, management system, ecological environment in pressure system and pollutant discharge in pressure system are more controllable. The regulation of water resource carrying capacity can start from these aspects.
