Abstract: 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.
