摘　　要：以离石区不同种植年限蔬菜大棚土壤为研究对象,应用单项质量指数与综合质量指数相结合的方法对大棚表层土壤中的7种重金属元素进行污染评价。结果表明:离石区土壤重金属含量随种植年限的增加而增加;各重金属元素的平均含量均低于《温室蔬菜产地环境质量评价标准》的标准限值;但有部分大棚土壤中Cd、Pb、Ni超过其标准限值。结合各重金属的单项质量指数和综合质量指数(0.64),将离石区温室蔬菜大棚的土壤环境质量等级定为2级,属于尚清洁水平。With different planting years in Lishi District vegetable greenhouse soil as the research object, method of application of single pollution index and comprehensive quality index combines the pollution evaluation of 7 heavy metals in surface soil in greenhouse. The results showed that the content of heavy metals in the soil increased with the increase in planting; limit the average content of heavy metals were lower than the standard greenhouse vegetable producing environmental quality standards; greenhouse soil Cd, Pb, Ni exceed the standard phenomenon. Combined with the single quality index of the heavy metals and comprehensive quality index （0. 64） .the soil environment quality in vegetable greenhouse Lishi District greenhouse was classified at level two, which was still clean level.
