综合比较法评价生态环境质量变化

Evaluation of ecological environment quality with comprehensive comparison

根据生态系统组成情况,利用特尔裴测定法,选定影响生态环境的因子,确定其权重,现场调查取得使用资料,判定各因子的作用分值,采用模糊综合法计算出生态环境变化前后的综合分值,以判定生态环境变化前后的好坏。

Based on the components of ecological system,the factors affecting ecological environment were chosen by Delphi approach,with its weight data gathered on the spot investigation.Then the comprehensive subweight before and after the environment changes were calculated by fuzzy comprehensive method,which could be used to judge the environmental state before and after the environment changes.
