矿区复垦土壤环境质量模糊评价--以平朔安太堡露天煤矿为例

The Fuzzy Appraisal for Environmental Uality of Reclaimed Soil in Mining Area-A Cast Study from Antaibao Opencast Mine of Pingshuo

通过野外调查、收集资料、室内分析、统计分析、模糊评价等方法,对平朔露天煤矿不同复垦基质的重金属污染元素进行了较为系统的分析与评价,结果表明大多数复垦土壤为一级标准,土壤质量基本上保持自然背景水平。以原地貌的环境质量为标准,根据最大隶属原则,可以看出人为扰动对各复垦再造地的环境质量的影响程度。

The methods of lab analysis, statistical analysis and fuzzy mathematics appraisal were used to analyze and appraise heavy metal pollution in different reclaimed soils in open coal mine. The resulted indicated that the great majority of reclaimed soil were as the first class standard, soil quality keep the natural background level basically. Take the original landform＇s environment quality as a standard, according to the Biggest subordination principle, the influence of artificial perturbation to each reclamation and reconstruction soil could be found.
