    摘要:

    提要: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。

    Abstract:

    Abstract: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 Qinghai was established. The basic assessment principles, criteria and geological indicators for the geo-environment vulnerability were proposed under this framework. The geo-environment 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.
