四川省矿产资源规划环境影响评价指标体系

通过对四川省典型矿区环境进行实地调查和对环境问题分类统计，建立了矿区环境问题与开发矿种的对应关系，并对矿产资源开发产生的环境影响程度进行系统识别；针对四川省的自然环境背景和已经存在的矿区环境问题，构建了四川省矿产资源规划环境影响评价指标体系框架，并用层次熵多目标决策分析模型对指标及因子进行定量化研究，较为全面地反映出矿产资源规划实施后对环境的影响程度，为宏观控制矿区环境质量提供了依据，对进一步完善矿产资源规划环境影响评价有一定的参考价值。

Target System for the Environmental Impact Assessment of Mineral Resource Planning of Sichuan Province

Based on the typical mining site survey and the classification statistics of environment problems of Sichuan Province, a correlation between the environment problems and ore types under exploitation is established and a system identification of the degree of environment impact of mineral resource development is made.In view of the natural environment background and existing mining environment problems in Sichuan Province, a target system framework for the environmental impact assessment of mineral resource planning of Sichuan Province is established.A quantitative study is made on the indexes and factors by a hierarchical entropy multi-objective decision analysis model.As a result, the degree of environmental impact when the mineral resource planning is completed is well reflected, providing a basis for controlling the quality of mining area environment and being of reference significance to the further improvement of the environmental impact assessment of mineral resource planning.
