| Abstract: | Water resources is an important natural resources in the world, and its security has been paid a great attention to all over the world. In northwest China, a typical arid area, the shortage of water resources is the principal factor restricting the sustainable development of the regional economy. To research the water resources security is of significance for the social and economic development in northwest China. In this paper, a case study on the security assessment of water resources is carried out in Yuli County, Xinjiang Uygur Autonomous Region by selecting 22 indexes in 6 classes and by using the fuzzy mathematical multi-factor second-level assessment model. The result shows that the water resources in Yuli County is currently in an extremely dangerous status. Therefore, some measures and suggestions are put forward, which are as follows: (1) To strengthen the macroregulation of water resources and rationally redistribute the water consumption; (2) To improve the irrigation techniques, complete the irrigation systems, and raise the utilization ratio of water resources; (3) To rationally exploit the groundwater resources. The study results can be referenced in the security assessment and rational exploitation and utilization of water resources in arid areas in northwest China. |
