基于GIS多准则空间分析(SMCE)的青海省矿产资源开发地质环境脆弱性评价

青海省具有丰富的矿产资源，其可持续开发战略与规划应建立在对地质环境脆弱性评价的基础上。笔者通过分析青海省环境地质问题和地质灾害发育的基本规律，建立了青海省未来矿产资源开发的地质环境脆弱性评价的框架。提出了地质环境脆弱性评价的基本准则和地质评价指标。在荷兰国际地球科学测量与观测学院（ITC）开发的GIS软件——ILWIS环境下，利用其新开发的空间分析功能的SMCE模块，对青海省的地质环境脆弱性进行了评价。结果表明，具有矿产资源远景开发的地区地质环境比较脆弱，对未来的矿产资源开发有着较大的制约作用。

Application of GIS-based spatial multi-criteria evaluation (SMCE) in the geo-environment vulnerability assessment for the development of mineral resources in Qinghai Province

There are plentiful mineral resources in Qinghai Province, China. The sustainable development strategy and planning of the mineral resources should be worked out on the basis of the geo-environment vulnerability assessment. This paper analyzes the geo-environment issues and geo-hazards in Qinghai. The assessment framework of the geo-environment vulnerability in Qinghal was established. The basic assessment principles, criteria and geological indicators for the geo-environment vulnerability were proposed under this framework. The geo-enviromnent vulnerability evaluation in Qinghai was carried out by using the new SMCE function modules of ILWIS, which is a GIS software developed by ITC. The results indicate that the prospect areas of mineral resources are located in areas of low geo-environment vulnerability. This means that geo-environmental conditions have major constraining effects on the future mineral development in Qinghai.
