Abstract: The index system of sustainability measure of water environment is constructed by wetland water environment structure, the state of wetland functions and human factors. The mathematical model of integrated sustainability index is: P=0.14P1+0.47P2+0.3P3+0.09P4, and the sub-indices are: water quality, water quantity, creature and land use change indices. In this study, we used gray relation analyses, Analytic Hiberarchy Process(AHP) and Subparagraph Linear Function Method to calculate the integrated index(P). The results show that: the overall trend of water environment sustainability in Zhalong wetland is declining, and its impact factors are detrimental to the sustainable development of Zhalong wetland.
