摘　　要：利用遥感影像分类技术监测分析了高潜水位开采沉陷区土地利用覆盖变化情况,并基于已有的不同地类下植物和土壤的碳密度统计数据,对2000—2006年高潜水位矿区土地利用覆盖变化驱动影响下的碳储量变化进行了分析,对比发现土壤碳储量、植物碳储量都有不同程度的减少,研究区总的碳储量减少了约16%;由此说明高潜水位矿区开采沉陷不仅引起了区域土地利用与地表覆盖类型改变,同时还引起了区域总碳储量的减少,应该加强对采煤塌陷区土地的管理和生态治理。The remote sensing image classification technology was used to study the land use change and its carbon reserve at a high groundwater level coal mining subsidence area based on the existing carbon density data of plants and soil under different land types from 2000 to 2006. It was proposed that the total carbon reserves of land and plants fell in different extent,and it can be seen that the total carbon reserves fell by almost 16% in the study area. Thus,mining subsidence at high groundwater level area not only caused the regional land use and surface coverage change,at the same time caused the reduction of carbon biomass decreased. Therefore,it is important to improve the land management of the mining area and ecological remediation.
