山西省矿山开发新增损毁土地年度监测与分析

    Annual monitoring and analysis of newly damaged land in mine development in Shanxi province

    • 摘要: 及时准确监测矿山开发占地变化状况是开展矿山地质环境监测的主要任务。本文以高空间分辨率遥感数据为主要数据源,采用人机交互解译方式,提取2018—2019年山西省新增矿山开发损毁土地状况,分析了矿山开发新增损毁土地数量规模、空间分异特征与扩展模式。结果表明:①新增矿山开发损毁土地类型以固体废弃物和矿山采场为主;②新增矿山开发损毁土地涉及矿种有51类,其中,能源矿产中的煤矿新增开发损毁土地规模居首位;③山西省忻州市、阳泉市和吕梁市的新增损毁土地图斑规模和数量在热点分析图上均表现高值的聚集,而晋南各地市与晋北的大同市等地区主要表现为扩展冷点区域;④新增矿山开发损毁土地扩展模式以边缘式扩展为主,其次为飞地式,填充式扩展的图斑数量与规模最少。

       

      Abstract: Timely and accurate monitoring of the change of mine development land occupation is the main task of mine geological environment monitoring.This paper uses high spatial resolution remote sensing data as the main data source, using human-computer interaction interpretation methods extract the annual mine development newly damaged land status in Shanxi province from 2018 to 2019, and the scale, spatial differentiation and expansion mode of newly damaged land in mine development are analyzed.The results show that solid waste and mine stopes are mainly the types of newly land damaged by mine development in Shanxi province from 2018 to 2019.The mine development process involves 51 kinds of minerals in Shanxi province from 2018 to 2019, and the mining activities of coal mines are the main reason for the expansion of newly damaged land; the scale and quantity of newly damaged land in many cities show high-value clusters in the hot spot analysis chart, including Xinzhou city, Yangquan city, and Lyuliang city.The south and north of Shanxi province belong to the expansion cold spot area.The sprawl mode of newly damaged land in Shanxi province from 2018 to 2019 is mainly edge sprawl, followed by exclave sprawl, and the number and scale of infill sprawl are the least.
