中文摘要	西藏多龙矿集区铜多金属矿产资源丰富,铜储量约2500万吨,排名中国第一。矿集区矿产资源的开发能带来巨大的社会经济效益,但青藏高原地区生态环境承载力有限,矿山开发容易造成生态环境的不可逆破坏。本文基于高分二号、Landsat8等遥感影像数据,采用人机交互解译方法提取多龙矿集区有关人类活动、水文、荒漠化、金属氧化物污染及草地覆盖等信息,进而分析研究区生态环境现状。分析结果表明:研究区生态环境整体仍处于较原始状态,未遭受过大型工业活动及人为活动破坏;区内主要植被类型为高原草原和高原草甸,高草地覆盖区面积较小且分布较集中;研究区荒漠化形势较为严峻,主要荒漠化类型包括沙漠化、石漠化及盐碱化等;矿区地表出现大面积褐铁矿化及孔雀石化,周边土壤及水系金属及重金属矿物含量超标;区内砂金矿盗采、超载放牧及地质勘探等人类活动均对当地生态环境造成一定影响。利用RS与GIS技术开展多龙矿集区生态环境调查研究,可为矿山的绿色选址及绿色矿山开发建设提供建议及技术支持。
英文摘要	Copper polymetallic mining area in Duolong,Tibet,is endowed by abundant mineral resources with a reserves of about 25 million tons,ranking the first in China.Mineral development in this ore cluster area will not only bring significant benefit for society and economy,but also cause irreversible damage to the ecological environment due to its limited bearing capacity.To understand the current situation of ecological environment,we extracted the related ecological environment information,such as social activities, hydrology,desertification,metal oxide,vegetation cover,and so on,from the dataset of GF-2 and Landsat 8.Analytical results show that the ecological environment in the study area is generally in a primitive state and untouched by large-sized industrial and human activities;the plateau grasslands and plateau meadows are the main vegetation types distributed in relatively small areas.But the problem facing this area is severe desertification including desertification,desertification and salinization,etc.Large-cale ferritization and malachitization occur in the mining area,around which soils and waters contain high contents of metals and heavy metals.But human activities in the mining area,such as illegal mining for placer gold,overload herds,and geological survey,all cause a certain influence on the local ecological environment.RS-and GIS-based investigation of the geological and ecological environment in the Duolong ore cluster area can provide some suggestion and technical support for location and construction of environmentally friendly mining.
