利用遥感(RS)与地理信息系统(GIS)技术对江仓露天矿区生态环境进行了研究,综合该研究区域生态环境影响调查结果,利用层次分析法构建了以自然环境影响因素和人为采矿活动影响因素2个子评价指标和植被覆盖、降水量、居民建筑活动占地、采矿活动占地等13个单指标的生态环境评价体系。确定各评价因子的权重值,通过定性描述和定量评价结合的方式阐述矿区内生态环境破坏情况,构建能够满足高海拔矿区生态环境评价要求的评价体系。
RS and GIS technology was applied to study Jiangcang open-air mining area ecological environment,the results of regional ecological environmental i MPact survey were integrated. An ecological environment evaluation system was established based on hierarchy process,which comprises 2 branch-evaluation indexes including natural environment factors and mining activities factors,and 13 signle indexes including vegetation,precipitation,resident building activity area and mining activities area,etc. Through the determination of weightings for each evaluation factor,an ecological environment evaluation system for high altitude mining area was established,to evaluate the damage to ecological environment within the mining area,combining qualitative description and quantitative evaluation.
