摘　　要：以襄汾县主要土壤类型褐土的7个土种的重金属污染现状为研究对象,采用单因子和综合因子指数法对土壤中重金属的污染现状进行评价,结果表明,不同土壤类型对重金属的含量有一定的影响,各土种的单因子污染指数均小于1,内梅罗综合污染指数除中壤轻度侵蚀耕种黄土质褐土性土和中壤浅位厚粘化层耕种黄土状碳酸盐褐土达到警戒线外,其余都在安全范围.襄汾县土壤未受到污染,尚属清净,适合农业生产.从整体的变异系数上看Ni的变异范围较大,污水灌溉和农药化肥的影响可能是造成Ni变异系数偏大的原因.The present situation of heavy metal is evaluated pollution index for seven of the major soil type of Brown Eearth in with single pollution index and comprehensive Xiangfen country. The results indicate that the different soil types affect the heavy metal content, each soil form factor of pollution index is less than 1. In addi- tion to farming soil in a mild erosion in loess Brown soil quality soils and cuhivated soil of shallow thick adhesive layer in loess-like carbonate Brown soils reach the alarm level, everything else was in the safety range. The soil is free from contamination, clean and suitable for agricultural production in Xiangfe efficient of variation, the variation range of Ni is larger, which may be due to the n country. From the overall co- effect of sewage irrigation, pesticide and fertilizer.
