根据乡村的地域特征,构建乡村人居环境满意度评价指标体系。运用模糊层次分析法建立模糊判断矩阵,通过偏差矩阵,调整模糊判断矩阵,并检验矩阵的一致性,得出各指标的权重。采用模糊综合评价法对乡村人居环境满意度进行评价,根据居民的自身愿望与现实感知的差异程度来确定乡村人居环境建设的突破口。从居民最关心的农村饮水安全入手,探讨了农村饮水安全的公共物品性质,认为政府的介入是保障农村饮水安全的关键,供给主体的多元化是确保农村饮水安全的有效途径。

The perfect harmony is important to rural human settlements (RHS) for sustainable development of rural region and country's stability.The difference between villagers' expectations and perceptions in reality is the key of how to construct RHS. Only by finding out what the villagers care most can scholars provide credible bases for governments to make rational policy. The paper tries to do some exploratory research on residents' satisfaction degree of RHS with the theories of public goods and fuzzy mathematics in forms of on-site investigation and questionnaire survey. It probes into the primary problems in the constructions of RHS from villagers' perspectives. Meanwhile, the paper gives some suggestions to promote the sustainable developments of RHS. Based on each town's regional characters, the paper constructs the satisfaction degree index system of RHS. The fuzzy judgments matrix is established through fuzzy analytic hierarchy process and checked whether the matrix is consistent with entropy method by using deviation matrix to adjust the fuzzy judgment matrix. The paper concludes the weight of each index, and evaluates the satisfaction degree of RHS on the method of fuzzy comprehensive evaluation. The differences between villagers' expectations and perceptions in reality determine the key-point of RHS construction. After the analysis of villagers' satisfaction of RHS, the paper argues that rural drinking water safety is considered to be the most urgent problem of RHS construction. This problem not only hinders the sustainable development of RHS seriously, but also prevents villagers from getting good health directly. Also, the paper discusses the characters of rural drinking water safety, and suggests the key of protecting rural drinking water safety is the strong intervention of governments. Rural drinking water safety, one part of public goods, consists of several related elements with different characters. So it is a effective way to promote diverst subjects of public goods supply, so as to ensure the safty of raral drinking water.
