摘要:

基于ZY-3卫星数据,建立煤矿区土地退化人为影响专题因素遥感解译标志,对神东煤矿区土地退化人为影响因素开展遥感监测。运用层次分析法构建土地退化人为因素影响强度评价指标体系,采用综合评分法计算研究区土地退化人为因素影响强度指数。结果表明:土地压占破坏是造成神东煤矿区土地退化的首要人为影响因素,人类矿业活动对该区土地退化的影响程度已达“强烈”级别。为定量估算神东煤矿区矿业开发对土地资源的占用破坏数量并预测矿区土地退化发展趋势,提出1种煤矿区土地占用破坏率的计算方法。研究表明,ZY-3卫星数据完全满足井工开采煤矿区土地退化因素调查对高分辨率卫星数据的需求。今后需加强煤矿开发秩序的有效监管和矿山环境遥感动态监测,以防人为因素对土地退化的影响程度日益加深。

Abstract:

Based on the ZY-3 satellite data related to the Shendong coal mining area, the matic remote sensing interpretation marks were established for artificial influencing factors of land degradation in the area, the factors monitored via remote sensing, a comprehensive intensity evaluation index system built up for the factors with the AHP method, and strength indices of the factors worked out with the comprehensive evaluation method. It turned out that land occupation by waste was the major form of land degradation caused by artificial influencing factors, and the influence of mining activities on land degradation in this area had reached the level of “strong”. To estimate quantity of the land resources occupied or to be occupied by waste and predict the trend of the land degradation as a result of development of the mining area, an algorithm was proposed for calculation of land occupation and damage rate in the coal mining area. The research shows that the ZY-3 satellite data are adequate to completely satisfy the requirements of the survey of land degradation caused by underground coal mining for high resolution satellite remote-sensing data, and it is essential to intensify orderly and effective management of coal mining and to monitor dynamics of the environment of the mining area via remote-sensing in order to stop the aggravating trend of the influence of the artificial factors on land degradation.
