江苏省盐城市沿海滩涂生态系统健康综合评价研究

江苏省盐城市是"海上苏东"战略的最前沿,是西太平洋海岸最大的滨海湿地,具有极高的生态价值。文章根据整体性、敏感性、主导性等原则,结合P-S-R模型,构建了沿海滩涂生态系统健康评价的三层指标体系。采用AHP--模糊数学--灰色关联复合模型对盐城沿海滩涂生态系统健康进行综合评价,首先通过AHP分析计算出各指标的权重,运用模糊数学建立隶属度矩阵,在此基础上通过灰色关联分析,比较盐城沿海滩涂生态系统健康的空间差异,并分析了差异产生的原因。

The Study of The Eco-health Assessment in Jiangsu YanchengCoast Wetland

Yancheng coast region of Jiangsu province is at the forefront of the strategy of Developing the sea in the east of Jiangsu province ,is the biggest coast wetland in the west coast of the Pacific, has the extremely high ecology value. The article according to the integrity, the sensitivity, dominant and other principle, using P-S-R model, has constructed the assessment index system of eco-health in Yancheng coast wetland. Carried on the synthesis appraisal model of the AHP-fuzzy mathematics-gray connection to the Yancheng coast wetland ecohealth evaluation, according to result ,compared with the Yancheng coast wetland eco-health regiondifference, and analyzed the reason which the difference produces.
