中文摘要： 水是湿地形成的先决条件和环境因素，湿地对水的依赖极化了水的敏感性。湿地水环境是指与湿地生态系统中的水相互关联、相互作用的各要素的集合。湿地水环境的可持续性度量就是通过建立湿地水环境的指标体系来测量、判断和评价湿地水环境是否是可持续的。识别湿地水环境系统，诊断湿地水环境的结构和功能，依据湿地水环境可持续性度量理论和数理方法是度量其可持续性的基础；构建湿地水环境可持续性度量指标体系，建立相应数学模型是测量、判断和评价湿地水环境的可持续程度的必要条件；而通过案例可以实证理论研究的科学性、实用性和可操作性。 遵循湿地水环境可持续性度量原则和指标体系构建原则，建立湿地水环境可持续性度量指标体系和数学模型，根据湿地水环境可持续综合指数P值的大小评定湿地水环境可持续现状和未来发展趋势。湿地水环境可持续性的评定标准根据湿地类型和不同区域及度量目标的不同而因时因地而异，但是，同类湿地水环境可持续性度量的评定标准应该相同。在研究中认为，将灰关联分析和层次分析方法应用于湿地水环境可持续综合指数的计算，具有科学性和简捷性。

英文摘要： Water is the precondition of wetlands formation, and the dependence of wetlands on it polarizes the water sensitivity. Wetlands water environment is the aggregation of factors which interact with water in the wetland ecosystem, and the sustainability measurement of wetlands water environment is to measure, judge and evaluate whether it is sustainable by establishing wetland water environment index system. Identifying the wetland water environment system, diagnosing its structure and function and utilizing sustainability measurement theory and symbolic method is the basis of measuring sustainability of wetland water environment. Meanwhile, establishing the index system of wetland water environment sustainability measurement and constructing corresponding mathematic model is prerequisite to measure, judge and evaluate its sustainability level. Further, through cases we can validate whether the theory research is scientific, useful and maneuverable. Following the principle of wetland water environment sustainability measurement and the principle of index system construction, we build the wetland water environment sustainability measurement index system. Then we use the integrated index (P) to evaluate the actuality and the future changes of the wetland water environment sustainability. The evaluation standard of wetland water environment sustainability varies with wetland types, regions and aims. However, evaluating wetlands of the same type, the standard must be the same. In this study, we use gray relational analysis and Analytic Hiberarchy Process (AHP) method to calculate the integrated index (P), which is scientific and concise.
