云南省昆阳磷矿地质环境问题区矿山地质环境评价

矿山地质环境评价是实现矿产资源合理开发利用和环境保护并重的重要举措。本文以高分2号遥感影像数据为基础，系统地研究了研究区矿山地质环境特征和主要矿山地质环境问题，据此厘定了矿山地质环境评价指标体系，运用AHP决策分析法确定评价指标权重值，基于ArcGIS技术平台，对研究区矿山地质环境做出评价。根据评价结果：将矿山地质环境划分为矿山地质环境影响严重区、较严重区、一般区和无影响区。结果表明：研究区矿山地质环境质量总体上较好。研究成果对于指导昆阳磷矿地质环境问题区的矿产资源可持续开发利用具有重要参考价值。

Mine geological environment evaluation in the Geological environment problem area of Kunyang phosphate rock in Yunnan Province

Mine geological environment evaluation is an important measure to realize the reasonable exploitation and utilization of mineral resources and environmental protection.This paper studied the mine geological environment characteristics and the main mine geological environment problems in geological environment problem area of Kunyang phosphate rock systematically based on the High score 2 remote sensing image data ,and determined the evaluation index system of mine geological environment according to it,using AHP decision analysis method determined the weight of the evaluation index,and evaluating the mine geological environment of the study area based on ArcGIS technology platform.According to the evaluation results:The mine geological environment is divided into mine geological environment serious area, more serious area, general area and no impact area.The results show that the quality of the geological environment in the study area is generally good.The research results have important reference value for guiding the sustainable development and utilization of mineral resources in the area of geological environment of Kunyang phosphate rock.
