湖泊生态系统健康评价指标体系

在探讨生态系统健康概念构架的基础上,寻求生态系统健康整体性评价的合适指标.根据生态系统健康评价的目的和指标筛选的原则,在充分考虑湖泊生态系统实际情况的基础上,从湖泊生态特征、自然功能和社会环境3个方面的评价指标中筛选出23项指标,并给出每个指标的量化标准,得出了适合湖泊生态系统健康评价的指标体系.该指标体系是一个由目标层、子系统层和评价指标层构成的3层递阶层次结构指标体系.

Evaluation index system for lake ecosystem health

Based on the conceptual framework of ecosystem health,appropriate indices for the integrated evaluation of ecosystem health were created.With full consideration of the actual status of the lake ecosystem,23 indices were selected from the evaluation indices covering the ecological properties,natural functions,and social environmental functions of the lake ecosystem,according to the purpose of evaluation of ecosystem health and principles of index selection.In addition,the grading standards were put forward for these indices,based on which an index system appropriate for the evaluation of lake ecosystem health was established.This system is a three-layer hierarchy-structured index system consisting of the target layer,the subsystem layer,and the evaluation index layer.
