摘　　要：现阶段国内外的土壤稳定化效果评价大部分选用模拟填埋以及酸雨情景下的毒性侵出方法,无法完全模拟填埋、绿化等不同用途和去向后污染向环境中释放的多种场景,同时也表征碳化不同环境下重金属释放的危险。设计并提出不同退耕还林模式下重金属污染土壤的生态恢复效果评估方法,将拉依达准则结合不同的数据处理方法,对数据进行删除以及填补。再利用“灰色关联度分析方法”组建不同退耕还林模式下重金属污染土壤的生态恢复效果评估模型,通过模型实现不同退耕还林模式下重金属污染土壤的生态恢复效果评估。At this stage,most of the domestic and foreign soil stabilization effects are evaluated using simulated landfills and toxic invasion methods in acid rain scenarios,but this assessment method cannot fully simulate the different uses of landfills,greening and other sources and the subsequent release of pollution to the environment.This scenario also characterizes the danger of heavy metal release under different carbonization environments.In view of the above problems,this paper designs and proposes methods for evaluating the ecological restoration effects of heavy metal contaminated soil under different returning farmland to forest models.Combine Layda criteria with different data processing methods to delete and fill data.Then,the“grey correlation analysis method”was used to establish evaluation models of ecological restoration effects of heavy metal contaminated soil under different returning farmland to forest models,and the model was used to evaluate the ecological restoration effects of heavy metal contaminated soil under different returning farmland to forest models.
