高分二号数据在湖北大冶矿山地质环境调查中的应用

Application of GF-2 satellite data to mine geological environment investigation in Daye, Hubei Province

遥感技术可用于监测和分析矿山开采活动造成的土地资源和生态环境破坏情况,对于矿区生态环境保护具有重要的现实意义.以湖北大冶为研究区,采用高分二号国产卫星遥感影像,在分析地表地物光谱特征和空间特征基础上,用波段运算和密度分割,对受污染的水体和植被进行增强处理并定性分析水体污染级别,用最大似然法监督分类对矿区进行土地利用分析,监测重要矿集区的矿山开发状况和矿山环境变化.就高分二号数据在大冶地区矿山地质环境调查应用进行探讨和分析评价,为合理保护矿区生态环境和国产高分数据在地质调查中的应用提供参考.

The land resources and ecological environment destruction caused by mining activities can be monitored and analyzed by remote sensing technology, and it is of great practical significance to protect the ecological environment of the mining area and establish a scientific evaluation reference system. With Daye in Hubei Province as the study area and by employing of the GF-2 satellite data, the authors enhanced the information of polluted water and vegetation, then qualitatively analyzed the pollution level of water using band operation and density division method based on the analysis of spectral features and spatial features of surface features. Land use was analyzed by maximum likelihood method to monitor mine development status and mine environment change in important ore concentration areas. The authors investigated and analyzed the application of GF-2 satellite data to mining geological environment investigation in Daye area, and the result obtained can provide reference for the reasonable protection of the mining area ecological environment and the application of the domestic high resolution satellite data in geological survey.
