基于遥感的察尔汗盐湖矿产资源开发状况调查研究

The Investigation of Mineral Resources Development Based On Remote Sensing in Golmud Salt Lake

位于青海省格尔木市北60km处的察尔汗盐湖是一个以钾、镁盐为主的大型综合性矿床,属于国家的重点规划矿区,虽然矿产开发为青海省经济发展作出巨大贡献,但同时也带来诸多矿山环境问题。本文以不同时相的Landsat系列卫星影像数据和法国SPOT-5卫星数据为信息源,利用遥感技术手段对该地区2008年和1999年的矿产资源开发状况以及矿山环境进行了信息提取,通过综合分析获取了可靠的实时数据,为保持矿产资源的可持续开发与利用,维护矿业秩序及综合整治矿区环境提供技术支撑和决策依据。

The Chaerhan salt lake,60 km north to Golmud City in Qinghai Province is a mainly potassium and magnesium salt deposits of large-scale and comprehensive,the focus of state planning area.Although the mineral development contributes greatly to economic development in Qinghai Province,but it also brought many environmental problems.In this paper,the Landsat image data and the French SPOT-5 satellite data of different times were used to the region,to develop the mineral resources and mining environment information.Through analysis of reliable real-time data,it provided a technical support and decision-making basis to maintain the sustainable development of mineral resources and their utilization,and to maintain the order in mining and mining environments.
