| 中文摘要: |
| 戈壁荒漠区属生态环境脆弱区,原生地质环境敏感性强,矿业开发一定程度上加剧了土地沙化、盐渍化和荒漠区砾幕层的破坏,但戈壁荒漠区以往矿山地质环境调查工作程度较低,亦亟需开展矿山地质环境调查与评价工作。通过基于遥感解译的地质环境调查,查明了矿山地质环境现状。建立了适用于戈壁荒漠区矿山地质环境评价指标体系,通过模糊数学综合评价与综合指数模型评价,得到模糊综合评判指数与综合评价指数分别为4.806、4.833,确定矿山地质环境影响程度为中度影响。基于遥感解译与模糊数学的评价方法在戈壁荒漠区有色金属矿山地质环境综合评价中有效可行,为有色金属矿山地质环境调查与评价提供了方法借鉴,为矿山地质环境保护与恢复治理及土地复垦提供了依据。 |
| 英文摘要: |
| The Gobi Desert is a typically eco-environmental vulnerable area which characterized by a high sensitivity of primary geo-environment. The survey of mine geo-environment in Gobi desert area is still inadequate though the development of mining industry has aggravated the development of Land-Desertification、Soil Salinization and the destruction of the gravel-curtain layer to some extent. it is also urgent to promoting the survey and evaluation of mine geo-environment in Gobi desert area. The investigation clarified the present mining geo-environment quantity condition through the survey based on remote sensing interpretation and built a mining geo-environment impact assessment index system that is applicable to the Gobi Desert area. Using fuzzy mathematics method combined with Mine geo-environment Index(MEI), The investigation carried out the mine geo-environment impact assessment index by fuzzy mathematics and MEI is 4. 806、4. 833,respectively, confirming that the influence level of mining geo-environment is moderate. The synthetic evaluation on Mining Geo-environment based on remote sensing and fuzzy mathematics is effective and feasible to nonferrous metal mine geo-environment impact assessment in Gobi Desert,while providing a reference for the geo-environment investigation and evaluation of non-ferrous metal mines, and a basis for mine geo-environment protection、 recovery management and land reclamation. |
