西藏生产矿山在用土地面积遥感调查与分析

Survey and Analysis about Using Land Area of Producing Mines in Tibet Based on Remote Sensing

为了分析西藏矿山在用土地情况,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2016年和2017年生产矿山在用土地面积,分析了其变化情况。分析结果表明,建筑用砂、锂矿、铜矿、钾盐、铅矿是生产矿山在用土地面积最多的5个矿种;2016—2017年,建筑用砂在用土地面积增加最多,其次是铜矿、建筑石料用灰岩、花岗岩、水泥用灰岩等矿种,说明当地对建筑用砂矿产品的需求量显著增加。

In order to analyze the using land area of producing mines in Tibet, remote sensing data acquired in 2016 and 2017, technical method combining about remote sensing information extraction and field investigation were used. The using land area of producing mines in 2016 and 2017 were surveyed. The change about using land area of producing mines in 2016 and 2017 were analyzed. The results show that, for using land area, five most mines are building sand, lithium, copper, sylvite and lead. From 2016 to 2017, for using land area changes, the increase most mine is building sand, some increase more mine are copper, Limestone for building stone, granite and limestone for cement. It shows that there was a significant increase in local demand for Building sand products.
