Evaluation of Water Resources Carrying Capacity in Yili Rive

Water resource carrying capacity is one of the physical bases relating to the development of the economy and people life.In this paper according to the actual condition of the water resources in Yili river and the status of the water resource supply-demand,selecting some evaluation factors such as available water resource per capita,practical water supply per capita,efficiency of water resources,irrigation ratio of arable land,water supply modulus,water demand modulus,quota of living water use and ecological water use ratio,using the Fuzzy-based evaluation of water resources,the water carrying capacity was evaluated on the status and different level years.The results of the evaluation showed that: at present the development and exploration of the water resources has been a certain degree,but the latent of the development was high.But as to the socioeconomic development,there would exist a serious conflict between water supply and water demand,and the water resource carrying capacity would decline.At last,some methods of improving the water resource carrying capacity were put forward.
