sensing based reclamation efficiency index (RSREI) was developed .The index combined four indicators ,such as DEM ,NDVI ,LST and TVDI ,which reflect the terrain conditions and hydrothermal conditions in study area .An addition of four indicators method was utilized to compress the four indicators into one .By comparing with the standard deviation method ,the RSREI calculated from the addition of four indicators method is more reasonable for the dynamic evaluation through the time .The RSREI was applied in reclaimed dump area in Pingshuo open-cast mine .As a quantitative indicator ,it is used in spatial-temporal analyzing and thematic mapping .Meanwhile ,the RSREI is expected to be an auxiliary indicator for filed measurements .%基于遥感信息技术提出遥感复垦效益指数(RSREI),该指数耦合了地形高程、植被指数、地表温度和土壤湿度4个评价指标,综合反映了区域的地形条件和水热条件。基于上述4个评价指标,利用多指标加和的方法集成各评价指标,通过与标准离差法相比,多指标加和方法计算得到的RSREI更适用于时间维度的动态对比。将RSREI应用于平朔露天矿区已复垦排土场,作为一个量化指标实现复垦效益的时空分析与专题制图,以期作为实地测量指标的辅助指标。
