摘要: 以河南大峪沟煤矿为研究区,在资料收集和野外调查的基础上,基于矿区4个时期Landsat5 TM和Landsat7 ETM+遥感数据,利用ERDAS IMAGINE 9.1和Arcgis9.3软件,采用像元二分模型法,结合数理统计方法和GIS空间分析技术,对研究区1988年以来21 a的生态环境变化规律进行了分析。结果表明,利用多时相遥感数据矿山生态环境解译方法对矿山生态环境动态变化进行监测分析具有较好的效果,矿区生态环境破坏与资源开采活动在空间上和时间上均有较高的一致性,且矿区生态环境变化速率与资源开采生产活动强度具有一致性。

Abstract: Taking Dayugou Coal Mine in Henan Province as a case,and based on data collection and field work,the variation rule of ecological environment in 21 a since 1988 is analyzed according to Landsat5 TM and Landsat7 ETM+ remote sensing data by using ERDAS IMAGINE 9.1 and Arcgis9.3 software,and Dimidiate Pixel Model,with combination of the statistical methods and GIS spatial analysis techniques.The results indicate that a good effect is obtained by using the multi-temporal remote sensing monitoring data to monitor and analyze the dynamic variation of mine ecological environment.Damage to the ecological environment in the mine is closely consistent with the resource extraction activities in time and space,and the variation rate of the ecological environment is positively correlated with the production capacity in the mine.
