西藏各行政区矿产开采强度遥感分析

Mining intensity analysis of each administrative region in Tibet based on remote sensing

矿产开采强度可以反映区域内矿产资源开采的集中分布情况,为制定相应的矿产资源规划、统筹地方经济发展等提供决策依据。为了分析西藏不同行政区域的矿产资源开采强度,利用2016年和2017年获取的遥感数据,使用室内遥感信息提取与野外现场调查验证相结合的技术方法,调查了西藏各行政区2016年和2017年的矿产资源开发占损土地情况。基于上述遥感调查成果,分析了西藏各行政区2016年和2017年的矿产资源开采强度,并分析了开采强度的变化情况。分析结果表明,墨竹工卡县、堆龙德庆区、达孜县、城关区、仲巴县是矿产开采强度最高的5个县;2016—2017年,扎囊县、墨竹工卡县、堆龙德庆区、桑珠孜区、乃东县是矿产开采强度增强最多的5个县,而城关区是开采强度减弱最多的地区。

Mining intensity can reflect the centralized distribution of mineral resources exploitation and provide a basis for decision-making about mineral resources planning,overall planning of local economic development,etc.The mining occupation and destruction land of each administrative region in Tibet were surveyed by field investigation and information extraction from remote sensing data acquired in 2016 and 2017.The mining intensity and changes of each administrative region in 2016 and 2017 were analyzed on the basis of the results of remote sensing investigation.The results show that,for mining intensity,five counties with the highest intensity include Maizhokunggar County,Doilungdeqen District,Dagze County,Chengguan District and Zhongba County.From 2016 to 2017,for mining intensity changes,five counties with the highest increasing mining intensity were Zhanang County,Maizhokunggar County,Doilungdeqen District Sangzhuzi District and Nedong County,whereas the county with most weakening mining was Chengguan District.
