摘　　要：以北京门头沟区典型废弃石灰石矿山为例,通过野外调查、采样和实验室分析,计算得到废弃采石场植被与土壤自然演替之间关系。研究发现,TM影像中废弃采石矿场b3/b4波段比均值与废弃采石场综合恢复指数Irq之间具有较强的相关性,据其回归方程利用遥感手段快速评估计算得到研究区其他废弃采石矿场的综合恢复指数。可见,实地植被-土壤调查分析与空间遥感监测技术能够相互验证对采石场生态恢复状态的评估。Three representative deserted limestone quarries at Mentougou District, Beijing were selected as examples in the study to explore relationship of vegetation with natural succession of the soil, through field survey, sample collection and laboratory analysis. Results show that organic matter content versus pH values of the soil samples are well related with restoration index （Irq）. Meanwhile, close correlation is also found between the normalized synthetic bands （b3/b4） and comprehensive restoration index （ Irq ）. A new empirical model is worked out from b3/b4 and Irq, and applied to quick calculation of comprehensive restoration index （Irq） of other quarries.
