摘 要：
河北省土壤铜含量丰富.全铜平均25.4ppm,高于全国、世界平均含量.有效铜(DTPA—C_u)平均1.17ppm,<0.5ppm低铜土壤只占耕地总面积的6%.高铜土壤多分布在城镇郊区、洼淀和矿区土壤上.铜在剖面中以淋溶为主,表层富集过程非常微弱.土壤铜含量决定于母质类型.在成土过程中其数量变迁与土壤机械组成、土壤有机质、土壤碳酸钙、土壤PH等有关.

摘 要：
Soils of Hebei have rich copper. The total copper content average 25.4ppm It is higher than that of either the world or the whole contry. Averageavailable - Cu( DTPA-Cu) gets to 1.17ppm. Only 6 percent of cultivatedland has a lower value than 0.5ppm. High copper content soils mostly locate on the suburbs,low-lying land and districts of mine. Being leached is the main moving form of Cu in soil profile.The process of surface concentrating is very very weak.Soil Cu content primarily depend on its parent material. During the forma-tional process of soil, the content is influenced by soil texture, organic matter, CaCO3 and soil PH, ect.
