摘　　要：针对煤炭开采对矿区及周围的森林生态环境产生剧烈扰动的问题,提出了长时间序列的开采扰动识别方法.基于1984年—2015年共20期的Landsat TM/ETM+/OLI长时间序列遥感影像,以美国西弗吉尼亚州布恩县为例,利用植被变化监测(VCT)算法,应用综合森林特征指数(IFZ),构建“IFZ-时间”时间序列轨迹,实现了森林矿区开采扰动的识别,得到扰动年产品,重建森林从扰动到恢复的整个历史周期,可以为矿区环境监测和生态恢复工作提供技术支持.分类精度评价结果显示研究区分类的总体精度达到83.2%,Kappa系数达到0.814,表明植被变化监测算法可以有效地提取森林矿区的开采扰动信息.Mining operation has a strong disturbance on the mining area and its surroundings,to monitoring which,a long time-series mining disturbance identification method is proposed in this paper.Based on long-timeseries Landsat TM/ETM+/OLI imagery from 1984 to 2015 for totally 20 periods and considering the IFZ index,the VCT algorithm is applied to Boone county in West Virginia.By constructing the“IFZ-Time”time series trajectory,this paper identifies the mining disturbance and reconstructs the disturbance history in forest mining area,and produces the disturbance year map,which can support environment monitoring and ecological restoration.The classification accuracy evaluation results show that the overall classification accuracy of the study area reaches 82.9%,while the Kappa coefficient reaches 0.814,revealing that the VCT algorithm can effectively extract mining disturbance information in forest mining areas.
