黄河三角洲湿地生态系统健康评价指标体系

在借鉴国内外现有生态系统健康评价研究成果的基础上,结合黄河三角洲的实际,提出生态系统健康评价指标选取的基本原则,从功能整合性、生态特征、社会环境3方面,构建一套以"3S"技术为核心,具有可操作性的湿地生态系统健康评价指标体系,并参考国内外评价指标标准,根据各指标对湿地生态健康影响的程度,将27个指标进行标准分级,利用层次分析法确定指标权重。最后选择垦利县作为研究区域进行湿地生态系统健康评价,结果表明,垦利县湿地生态系统健康状态脆弱,应加强保护。

Assessment indicator system for ecosystem health of wetlands in Yellow River Delta

Based on foreign and domestic research on ecosystem health assessment, the basic principles for selecting indicators for ecosystem health assessment in the Yellow River Delta were proposed with consideration of the actual conditions in the area. With consideration of functional integration, ecological characteristics, and social environment, an operational assessment indicator system for the ecosystem health of wetlands was constructed using 3S technology, which was regarded as the key technology. With reference to some foreign and domestic evaluation criteria, the 27 indicators were classified into different grades according to their influences on the ecosystem health of the wetlands. AHP was used to determine the weights of the indicators. A case study was conducted in Kenli County for assessment of the ecosystem health of the wetland, verifying that the constructed indicator system is reasonable.
