【摘要】 以白音诺尔铅锌矿为研究区域,选取1985年和2013年遥感影像为数据源,以GIS技术及ArcGIS10.0软件为平台,对矿区的土地利用/土地覆盖变化进行分析。结果表明:研究区1985年和2013年的土地利用类型都是以有林地、草地为主;研究期内,有林地面积大幅度减少,总面积净减1197.51hm2,年均减少2.37%;尾矿库、矿区道路、排土场等工矿仓储用地大幅度增加,年均增幅均超过8%;有林地是其他土地利用类型尤其是草地、尾矿库和工业区新增部分的主要来源。景观格局向着多样化、复杂化和破碎化的方向发展,景观异质性增强,生态稳定性有所降低。更多还原

【Abstract】 In the study,we used GIS to analyze the land use / coverage change of Baiyinnuoer lead-zinc mine based on the satellite image data in 1985 and 2013. The result indicated that woodland and grassland were dominant in the study area in both 1985 and 2013. From 1985 to 2013,the area of woodland decreased by 1197.5hm2,on average,reduced 2. 37% annually. The land for construction,such as tailings,mining road and dump,greatly increased with average increase more than 8% annually. Newly added grassland,tailings and industrial area were mainly from woodland. In conclusion,the expansion of the mineral resources exploitation led to the decline in woodland and increase in construction land. Landscape pattern of local area developed in diversification,complication and fragmentation.更多还原
