摘要
为对陇南地区矿山地质环境进行保护与恢复治理,采用GIS和RS技术,使用SPOT5遥感数据,对陇南金矿区矿山地质环境进行评价。从地质背景和矿山开发两个方面构建评价指标体系,运用层次分析法计算指标权重值。并根据指标加权平均法建立数学模型,使用MapGis软件,对各影响因子进行量化分析。评价分区结果基本反映陇南金矿区矿山环境问题的分布特点。
In order to rehabilitate and protect the Longnan mining geo-environment,the geo-environment in the Longnan goldmine area is evaluated by using the GIS RS technology and SPOT5 remote sensing data.The evaluation index system is set up in terms of geological background and mining,with weighted values calculated by analytic hierarchy process.The weighted average method is used to form a mathematical model and MapGis software is used to make quantitative analyses of the cause-factors.The results basically reflect the distribution of the geological environment problems in the Longnan goldmine area.
