摘　　要：采用了空间遥感技术与地面植被、土壤调查分析等手段综合监测评估废弃采石场自然恢复状态,可为进一步实施生态恢复治理提供可靠的数据支持。结果表明:废弃采石场土壤采样点恢复指数(Ir)与土壤样方pH、有机质有较好的相关性;废弃采石场恢复综合指数(Irq)与遥感模型反演结果具有较强的相关性;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恢复状态的评估。同时提出利用遥感波段比值快速监测评估废弃采石场生态恢复的可行性建议。A study was conducted to assess and monitor the abandoned quarries using GIS and remote sensing techniques together with field survey. Results indicate that organic matter content and pH value of soil sample plot in the abandoned quarries are well related with the restoration index. The synthetic normalized bands （b3/b4） are closely correlated with the compre- hensive restoration index, Remote sensing technique is an effective tool to monitor vegetation restoration, and field survey is able to assess the capability of the remote sensing model and to describe the state of a quarry. A feasible suggestion is g4ven on rapidly monitoring and assessing the ecological restoration of a quarry by band ratio of remote sensing.
