云南省北部地区矿产资源违法开采遥感动态监测研究

矿产资源违法开采不仅造成资源的浪费,还破坏矿山地质环境,不利于生态环境的保护。该文基于高分辨率卫星遥感影像,借助GIS空间数据处理平台,对云南省北部地区2011—2015年矿产资源违法开采活动进行了遥感监测,通过野外实地核查,得出了5年内矿产资源违法开采遥感动态监测结果,分析了违法图斑的时空变化趋势和原因,并提出相应的对策和建议。对维护矿业秩序,保护环境,促进矿产资源的可持续开发利用起到重要的作用,同时也为云南省国土部门执法监管提供数据支撑和决策依据。

Study on Remote Sensing Dynamic Monitoring of Illegal Mining of Mineral Resources in Northern Yunnan Province

The illegal exploitation of mineral resources will not only cause the waste of mineral resources, but also cause serious damages to geological environment of the mine. It is not conducive to the protection of ecological environment. Based on high resolution satellite remote sensing images, by using GIS spatial data processing, remote sensing monitoring of illegal mining activities to mineral resources in the northern Yunnan province has been carried out. Through field verification, remote sensing dynamic monitoring datas of mineral resources exploitation in five years have been gained, illegal plots of the temporal and spatial trends and causes have been analyzed, and the corresponding countermeasures and suggestions have been put forward. It will play an important role in maintaining mining order, protecting environment and promoting sustainable development and utilization of mineral resources. It also provides data support and decisionmaking basis for law enforcement supervision in Yunnan province.
