摘要:

为了更好地对黄河三角洲自然保护区湿地生态系统进行健康评价。本研究根据自然保护区特征和湿地生态系统健康的内涵,基于欧氏距离理论,从水、土壤、生物和社会4方面选取13项指标构建了湿地生态系统评价体系,对保护区生态系统健康状况进行综合评判,并采用指标诊断方法分析保护区存在的问题。结果表明:保护区生态系统健康指数(A值)为0.656;水源保证率、土壤pH、植物群落动态平衡、动物群落动态平衡、人口密度、取水量与储水量比值、湿地产出价值与投入资金比等7个指标对A值的贡献为正;土壤有效磷、湿地资金投入能力和供给功能种类等3个指标对A值的贡献为负。本研究基于欧氏距离的湿地生态系统健康评价方法较真实地反应了保护区生态系统健康情况,分析了现存问题,并为进一步改善保护区提供了建议。

Abstract:

In order to better evaluate the health of the wetland ecosystem in the Yellow River Delta Nature Reserve, according to its characteristics and the connotation of wetland ecosystem health, we used the Euclidean distance theory and selected 13 indicators from four aspects of water, soil, biology and society, to construct the assessment system of the wetland ecosystem and evaluate the ecosystem health. Then, we analyzed the existing problems of the reserve based on the index diagnosis method. The results showed that the ecosystem health index (A value) was 0.656. The water guarantee rate, soil pH, dynamic balance of plant community, dynamic balance of animal community, population density, ratio of water extraction to water storage, ratio of wetland output value to input capital contributed positively to A value. The contribution of soil available phosphorus, wetland capital input capacity and supply function type to A value was negative. The evaluation method adopted by this study on wetland ecosystem health based on Euclidean distance could accurately reflect the ecosystem health, the existing problems were analyzed, and some suggestions on further improvement of the natural reserve were put forward.

Key words: the Yellow River Delta area, natural reserve, Euclidean distance, wetland ecosystem, evaluation method
