三江源湿地生态健康状况的评价

Analyzing and Assessing on the Ecological Environment Health of Wetlands in Sanjiangyuan

摘要: 本文以生态系统健康理论为基础，构建了以景观格局指数为主的活力–组织力–弹力–生态系统服务的生态健康评价体系，来研究三江源湿地的生态健康性。采用层次分析法(AHP)确定评价指标及各斑块类型的权重，结合计算出的景观格局指数值，利用综合指数法评价了三江源地区湿地环境的生态健康状况。通过对比2018年与1988年的景观指数值表明三江源湿地景观破碎度增大，景观异质性增强，景观的形状复杂化和不规则化增大。

Abstract: Based on the theory of ecosystem health, this paper constructs an ecological health evaluation system based on landscape pattern index-based vitality-organization-elasticity-ecosystem services, and studies the ecological health of Sanjiangyuan wetlands. Using the hierarchical analysis method (AHP) to determine the evaluation index and the weight of each plaque type, combined with the calculated landscape pattern index value, the ecological health status of wetland environment in Sanjiangyuan area was evaluated by the comprehensive index method. By comparing the landscape index values in 2018 and 1988, it is shown that the landscape fragmentation of Sanjiangyuan wetland severity increases, the landscape heterogeneity increases, the shape of the landscape is complicated and irregularly increases.
