基于水匮乏指数模型的朝阳市农村地区水安全评价

THE WATER SECURITY PROBLEM IN RURAL AREAS OF CHAOYANG CITY

水安全是人类生存、城市建设、社会稳定的前提,更是农村地区经济发展、物产丰富、人与环境和谐相处的最基本因素,水安全的好坏可以严重影响到农村的发展进程。通过建立水匮乏指数的模型对朝阳市农村地区的水安全来综合评估。分别从资源、途径、利用、能力和环境这五个因素入手,结合农村地区的水资源现状选取指标。应用熵权法和层次分析法获得综合权重,将所得权重应用到水匮乏指数模型,计算出其水安全结果,得出朝阳市农村地区的整体状态由不安全向安全过渡。

Water security is the premise of survival, the urban construction, social stability, especially in rural economic development, rich products, people and the environment of harmony is the most basic factors, so the stand or fall of water security can seriously affect the process of rural development. It can be evaluating the water security in rural areas in Chaoyang by establishing the model of water shortage index. Respectively from, ways and utilization of resources, capabilities, and environment of these five factors, combining with the present situ- ation of water resource selection index of rural areas. Application of entropy method and the analytic hierarchy process to obtain the comprehensive weight, applied the weight to water shortage index model to calculate the wa- ter security results. It concluded that the overall state of the rural areas in Chaoyang from is unsafe to safety.
