中文摘要：

西藏甲玛铜多金属矿床在开发过程中涉及了诸多土地利用/覆被方面的保护问题,作者采用IKONOS高清遥感影像,在GIS和景观生态学理论的支持下通过计算该矿区及其周边的土地利用/覆被景观格局指数,对该地区的土地利用现状进行了分析和评价。结果表明：草地是研究区的景观基质,对甲玛矿区整体景观格局的影响程度最大;灌木林地类破碎度最大,大部分斑块镶嵌在草地类中;裸露岩石类破碎度较低,大部分斑块分布集中;建设用地、耕地和水域对甲玛矿区整体景观影响程度最小。建议在矿区开发时,坚持开发与治理并重;在矿区复垦时,改良土壤基质,保护水资源,以种植草地为主,灌木林地合理地镶嵌在草地类中,从而保证绿色矿山的合理开发利用以及对西藏脆弱生态环境保护的目的。

英文摘要：

The exploitation process of the Jiama copper polymetallic deposit in Tibet of China has involved numerous protection problems of the land use/land cover.The authors of this paper adopt IKONOS HD image to calculate the land use/land cover and landscape pattern index under the support of Geographic Information System and the theory of landscape ecology.Based on this,they analyze and evaluate the present situation of the land use in this area.The final results indicate that there are four main factors to influence the landscape pattern of this area.First,the grassland is the landscape matrix of the study area and has the greatest effect on the whole landscape pattern of the Jiama mining area;secondly,the shrub forestland has the largest fragmentation,and the majority ofthe landscape patches are set in the grassland types;thirdly,the fragmentation of the bare rock types is minimum,and most of the landscape patches are concentrated;and fourthly,the land used for construction,cultivated land and water areas have the lowest effect on the whole landscape of the Jiama mining area.The authors suggest that people have to lay equal stress on the exploitation and management during exploiting the mining area and improve the soil matrix and protect the water resources in the mine reclamation,plant mainly grass and inlay the shrub land into the grassland reasonably in order to ensure the rational exploitation and utilization of the green mine and the objective of protecting the delicate ecological environment in Tibet.
