Abstract：Based on the investigated and measured data of 14 sample plots in 5 typical agricultural lands in Guchegou project area of Zuoquan County , the contents of Cu and Zn in soil at different depths of 0~10 , 10~40 and 40~60 cm were determined with TAS-990 atomic absorption spectrophotometer , and their space distribution were analyzed by mathematical statistics and geostatistical methods based on GIS .The results showed that the ranges of Cu and Zn contents in project area were 0.002~0.270 mg/kg and 0.015~0.185 mg/kg respectively , which were very lower than those of the background values of Shanxi Province .The clear vertical distribution trends of Cu and Zn contents in different farmland soil in project area were not observed . The Cu and Zn contents in 0~10-cm soil in study area showed a log -normal distribution and affected large-ly by agricultural activities .
