基于高分辨率遥感影像的江苏省矿产开发状况监测

Remote Sensing Monitoring of Mineral Development Status in Jiangsu Province Based on High-resolution Remote Sensing Image

为了充分发挥遥感技术在矿产资源开发、矿业秩序维护及矿山环境整治等方面的技术优势,以多平台中高分辨率遥感数据为信息源,首先采用几何配准、影像融合等多种技术对遥感影像进行预处理,然后建立了各种矿山地物解译标志,最后按照"由已知到未知、先易后难、逐步解译"的原则,因地制宜地采用多种人机交互信息提取方法,对2016年江苏省矿产资源开发状况进行了监测分析。通过监测结果综合分析和野外验证,获得了矿山开采图斑共计341处,其中,疑似违法开采图斑78处,疑似违法开采图斑包括疑似越界开采和疑似无证开采2类,数量分别为19处和59处。根据上述验证结果,对开采图斑的时空分布规律和动态变化特征进行了分析,可为该省矿政管理、国土空间用途管制工作提供可靠依据。

In order to make full use of the technical advantages of remote sensing technique in the exploitation of mineral resources,the maintenance of mining order and the improvement of mine environment,taking multi-platform and high-resolution remote sensing data as the information source,firstly,the image data is preprocessed by several processing techniques,such as image gemetric registration and image fusion,then,the interpretation markes of several mine features are established,finally,according to the principal of from know to unknow,easy before hard and gradual interpretation,a variety of human-computer interactive information extraction methods are adopted appropriately,monitoring and analysis of the mineral development status in Jiangsu Province in 2016 are conducted.Through the comprehensive analysis of monitoring results and field verification,a total of 341 mining spots are obtained,among them,the number of suspected illegal mining spots is 78,the suspected illegal spots can be divided into suspected cross-border mining and suspected unlicensed mining,their numbers is 19 and 59 respectively.Based on the abvoe disucssion results,the temporal and spatial distribution regularities and dynamic characteristics of the mining spots are analyzed,so as to provide reliable reference for national mining administration,land and space use control.
