废弃矿区环境恢复状况遥感监测研究

Remote sensing monitoring and research of abandoned mining zone environment

废弃矿区环境恢复监测对合理开采矿区具有重要的指导意义。以双鸭山废弃矿区为例,基于该区域2000年和2009年的MODIS数据,利用NDVI对两期的植被覆盖度变化进行了统计分析,总结了这两期的植被覆盖在时间和空间上的变化特征。采用分类方法,对比分析废弃矿区土地利用在时间序列上的变化情况。结果表明,双鸭山市废弃矿区植被覆盖度在时间特征上有了一定的提高。为废弃矿区的环境调查与生态恢复模式的研究提供了技术支撑。

The restore monitoring of abandoned mining zone environment has important guiding significance to rational mining mine. Taking Shuangyashan Mine as an example, this paper estimates the vegetation fractional cover respectively using two of the MODIS data in 2000 and 2009. Based on the NDVI, it makes statistical a- nalysis on the two changes of the vegetation fractional. It sums up the characteristics of the changes of time and space over the years. Then a comparative analysis of the change of land in disused mine with the classification method. Finally, the analysis showed that the vegetation coverage of abandoned mining zone in Shuangyashan had certain enhancement on the time characteristics by remote sensing monitoring. It provides technical sup- port for the environment investigation and study of ecological recovery mode.
