基于遥感动态监测的吉林省矿山地质环境及生态修复变化特征分析

Analysis on characteristics of mine geological environment and ecological restoration changes in Jilin Province based on dynamic remote sensing monitoring

为开展吉林省矿山地质环境变化趋势分析和矿山生态修复前景研究,利用2015—2019年获取的国产高分辨率卫星遥感数据和多源信息资料,采取自动化信息提取和人机交互解译相结合、室内综合研究与实地调查验证相结合的方法,对吉林省矿山地质环境及生态修复状况开展了遥感动态监测。通过对监测结果进行矿山地质环境及生态修复变化特征分析,基本掌握了该省矿山开发压占土地资源、损毁土地资源、矿山地质灾害、矿山环境污染和矿山生态修复的现状及其变化趋势。分析成果比较客观、准确,取得了较好的卫星遥感监测应用效果,可为该省深入推进山水林田湖草沙生态保护修复工程提供参考依据。

This study aims to understand the variation trend of the geological environment and the ecological restoration prospect of mines in Jilin Province.Using the 2015—2019 high-resolution remote sensing data from a domestic satellite and other multi-source information,this study carried out the remote sensing-based dynamic monitoring of the geological environment and ecological restoration of mines in Jilin Province by means of automatic information extraction,human-machine interactive interpretation,in-door comprehensive research,and field surveys and verification.The analysis of the changes in the geological environment and ecological restoration of the mines based on the monitoring results allowed for basically ascertaining the current situations and variation trend of the occupation of land resources by mines,damage to land resources by mines,and the geological disasters,environmental pollution,and ecological restoration of mines in Jilin Province.The analysis results are objective and accurate,indicating good application results of remote sensing-based monitoring.The results of this study can provide references and bases for further promoting the ecological protection and restoration engineering of mountains,rivers,forests,lakes,grass,and sand in Jilin Province.
