黄土区大型露天矿区土壤质量评价指标研究

STUDY OF THE LARGE-SCALE OPENCAST MINE OF LOESS AREA SOIL QUALITY INDICATORS

土壤质量评价是土壤质量研究的基础和重要内容之一。以平朔露天煤矿区为研究对象,在对矿区充分调查研究的基础上,建立由土壤物理指标、化学指标、生物指标和侵蚀指标4个一级指标和17个二级指标组成的指标体系。运用专家打分法确立了各级评价指标的权重,建立数学模型将指标定量化,根据平朔矿区特点确定了指标分级标准,并进行了评价。评价结果显示:原地貌、采矿后、复垦初期和复垦8年后土壤质量分别为4级、6级、5级和4级。

The soil quality evaluation is one of the basis and important content of the soil mass studies.This research takes Pingshuo opencast mine area as the research object.With the foundation of well investigated of research to the mineral area,we build up the indicator system which include 4 first-degree indicators : the soil physical indicator,chemistry indicator,living creature indicator and the erosion indicator sign and 17 second–degree indicators.The method utilized expert to give a score to establish an al...
