【摘要】 以生态系统健康及压力-状态-响应(PSR)模型作为研究方法,根据江苏盐城淤泥质海岸带湿地生态系统的特点,通过直接从地理信息数据及其处理数据中提取相关指标,建立了一套湿地生态系统健康快速评价模型,揭示了盐城淤泥质海岸带湿地生态系统健康状况的空间分布规律。研究结果表明:(1)盐城淤泥质海岸带湿地生态系统健康状态良好的占22%,相对一般的占67%;健康状态较差的占11%;(2)王家糟港-老坝港段湿地健康状况最好,生态健康指数达0.87,斗龙港-四卯酉港段湿地健康状况最差,生态健康指数为0.32;(3)盐城淤泥质海岸带湿地生态系统健康状况退化的最主要原因是围垦和工农业污染。更多还原

【Abstract】 According to the theories and approaches of the ecosystem health and the press-state-response model,wetland ecosystem health in silting coastal area of Yancheng City was assessed rapidly based on the indicators directly extracted from the GIS and RS data.The study built a model for rapid assessment of wetland ecosystem health,and explored the spatial distributing rules of wetland ecosystem health in silting coastal area of Yancheng.Following results were obtained: (1) In the structure of wetland ecosystem health of the silting coastal area of Yancheng ,excellent area accounts for 22%,generic area 67%,worse area 11%.(2) The health of the district among Wangjiazao Port and Laoba Port is the best,where the value of health index reach 0.87.Meanwhile,the health of the district among Doulong Port and Simaoyou Port is the worst,where the value of health index is only 0.32.(3) The main reasons,cause the damage to wetland ecosystem,are attributed to the reclamation and pollution of industry and agriculture.更多还原
