以水系沉积物样品为研究对象,采用综合指数法对研究区进行了土壤环境质量评价.其结果表明:研究区总体上土壤环境质量较好,但中污染区和重污染区占研究区面积的16.5%,土壤环境质量属于局部污染严重.该研究评价结果为农、牧、林业的规划提供了基础的地球化学资料.

The paper assessed soil environment quality of the study area by the comprehensive index method,tak-ing stream sediment samples as the research subject. The results show that the soil environment quality in the study ar-ea was generally favorable. However,the secondary pollution area and the heavy pollution area accounted for 16. 5 %of the study area's acreage. The soil was concluded to be badly polluted in local areas. The assessment provided basic geochemical data for the planning of agriculture,herding and forestry in the region.
