新疆地区矿产开采强度变化遥感分析

Mining Intensity Change Analysis in Xinjiang Based on Remote Sensing

为切实掌握新疆地区矿产资源开采发展趋势,提出了一种利用新增矿山占损土地面积、新增矿山恢复治理面积及行政区国土面积三大参量信息描述的单个矿山和不同行政区矿产开采强度变化评价方法,并分析了新疆地区各矿山以及各行政区2018—2019年间的矿产资源开采强度变化情况。结果表明:与传统的矿产开采强度评价方法相比,该方法具有涉及参量少、算法简单、易于实现的特点;新疆地区矿产资源开采强度呈增强的趋势,就矿山而言,矿产开采强度增强有2 003个,开采强度减弱有463个;就不同区县而言,矿产开采强度增强的区县有94个,其中裕民县、伊吾县、托里县等13个区县是矿产开采强度增强最多的县(区),而矿产开采强度减弱最多的地区有新市区、乌苏市、和田市等6个。

In order to clarify the development trend of mineral exploitation in Xinjiang,an evaluation method of mineral exploitation intensity change of single mine and administrative region is proposed by using the mining additional occupation land,rehabilitation land and the land area of administrative region. The mining intensity changes of each mine and administrative region from 2018 to 2019 were analyzed by this evaluation method. The results show that,compared with the traditional mining intensity evaluation method,this method has the characteristics of less parameters,simple algorithm and easy implementation;through analysis,the mining intensity in Xinjiang shows an increasing trend. For mining companies,the mining intensity has increased by 2003 and weakened by 463;for each county,there are 94 counties with enhanced mining intensity,of which 13 counties including Yumin county,Yiwu county,Toli county have the highest mining intensity,and six districts including New Urban areas,Wusu,Hotan have the most weakening mining intensity.
