摘要 湿地水环境的持续性度量的指标体系是从湿地水环境系统结构、功能状态和人为因素三个方面构建的。扎龙湿地水环境可持续综合指数的数学模型是:可持续综合指数P=0.14P1+0.47P2+0.3P3+0.09P4。分指数(PI)分别是:水质指数、水资源量指数、生物指数和土地利用变化指数。计算过程运用了灰关联分析法、层次分析法和分段线性函数等方法,结果表明,扎龙湿地水环境可持续性的总体趋势在减弱,其影响因子已经不利于扎龙湿地生态系统的持续发展。 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.
