Remote Sensing Monitoring And Analysis Of Mineral Resources Development In Beijing

Remote sensing technology has been widely used in the investigation and monitoring of mineral resources development environment.The research work of this paper is based on the "Yanshan metallogenic belt and Yunnan Nanping and other key mine area mine development remote sensing survey and monitoring" ? "Beijing-Tianjin area mine environmental monitoring" and "Beijing-Tianjin area mineral resources development environment remote sensing monitoring" project,choose the Beijing area as the research area,this paper makes a remote sensing extraction of the development information of mine development in Beijing from the beginning of 2010 to 2015,through the superposition of mine development status change information access to the annual development of the state of the project layer,carried out a comprehensive analysis of the development of mineral resources in Beijing area and trends,achieved the following main results:1?The paper is based on the change of mining development,experimental study on the variation of two remote sensing images by Euclidean space distance method,principal component transform method and vector angle method,on the basis of this,a comparative analysis of different change detection methods was carried out by selecting typical areas of mine change,it is concluded that the multi-band principal component method is the optimal change detection method in this experimental area.On the basis of this,the multi-band principal component method is used to detect and extract the change information of mine development situation in Beijing 2010-2011,2011-2012,2012-2013,2013-2014 and 2014-2015.2 ? This paper based on the information extraction of mine development in Beijing,to 2010 mine development status of the results for the bottom map,and then push back to 2011,2012,2013,2014,2015 the development of the mine situation thematic layer.Through field verification and comparative analysis with the results of the previous year to carry out the annual development of the results of the accuracy of verification results,field validation accuracy of 80%,compared with the previousresults,the total precision of metal mineral extraction is 91%,and the total precision of non-metallic mineral extraction is 87%.3 ? This paper summarizes the results of mineral resources development in Beijing from 2010 to 2015,this paper discusses the trend of mineral resources development,the analysis of illegal areas,,the analysis of illegal types,,the analysis of the main minerals,,the analysis of illegal mining methods,,the analysis of illegal economic types and so on,analyzes the order and development trend of mining industry in Beijing,and illustrates the drivers of this trend.On the basis of this,in order to ensure the sustainable exploitation of mineral resources in Beijing,the corresponding measures for sustainable development are put forward.
