西北地区矿山环境地质问题及动态数据库建设
The problems of environmental geology and database for mining in Northwestern China

摘要: 西北地区矿产资源丰富,矿业开发已成为地区经济发展的主要经济支柱。但是由于该区生态环境脆弱,不合理的矿业开发导致矿山环境地质问题严峻,部分矿区呈现加速恶化势态。资源损毁、地质灾害、环境污染是矿业活动的主要环境地质问题。矿业引发的地质环境问题与矿产资源类型、开发方式、地域条件及矿山企业的规模、性质关系密切。在研究分析矿山环境地质问题的基础上,建立了以MAPGIS为平台的可视化动态环境地质数据库。Abstract: The mineral resources in the Northwestern China are very abundant,and mining industry has become the importan teconomic main stay of the district. The ecologic environmental backg round in the area is very poor,the predatory mine exploration in the recent 50 years makes it more serious. The main environmental geological problems of mine exploration are to destroy environmental resources,to cause geologicaldisa sters and result environmental contamination.The different mines in differen tareas,such as petroleum,gas, coal,metal,nonmetal,building material and salt,may cause differen tenvironmental geological problems.Based on MAPGIS,the database of Windows'style is set up.
