ECOLOGICAL EVALUATION ON PANJIN WETLAND BASED ON ANALYTIC HIERARCHY PROCESS
-
摘要: 根据多年对盘锦湿地的调查研究，参照国内外湿地生态评价的指标和方法，选用反映湿地生态服务功能、生态保护功能和社会文化价值的12项指标，运用层次分析法对盘锦湿地进行生态评价.评价结果显示，盘锦湿地整体生态环境较好，其中均化洪水功能、调节气候功能、旅游观光价值、保护生物多样性、生态系统稳定性等功能，在决定湿地价值时起着重要作用.评价结果CEI值为0.7082，在（0.7，1]之间，表明盘锦湿地整体生态环境较好.针对盘锦湿地，地面沉降问题、地表土壤、植被的破坏、环境污染问题、地下水过量开采问题，提出了相应的对策，为湿地保护和开发利用提供参考.

Abstract: Based on years' investigation of Panjin wetland, with reference of the indexes and methods of wetland ecological evaluation at home and abroad, twelve indexes reflecting wetland ecological service, protection and social cultural value functions are selected to conduct the ecological evaluation on Panjin wetland by AHP. The result shows that the overall ecological environment is good (CEI=0.7082). The functions of flood homogenization, climate regulation, tourism value, biodiversity conservation and ecosystem stability play important roles in determining the value of wetland. Countermeasures are put forward against the problems of land subsidence, surface soil and vegetation destruction, environmental pollution and groundwater over-exploitation in Panjin wetland, which provides reference for wetland protection and exploitation.-
