| 摘 要： | 以B城地区土壤柱状剖面中主要重金属的含量水平、分布规律和赋存状态为基础，运用环境变化过程中的物质交换与循环理论，探索重金属污染物在土壤纵向剖面的传输途径、迁移特征及其聚集、释放机理，通过对土壤剖面中重金属形态的分析实验，研究了重金属各种形态在土壤剖面中的分布特征。对庑殿(WU)土壤钻孔剖面的研究发现，在深度为13．66～16．00m之间的土壤层，pH剧烈变化，重金属元素含量明显增高，初步判断该层位是污染物的主要累积层位。 |

| Abstract: | Based on the contents, distribution and existing states of heavy metals in the column profile of soil in B area, this paper discussed the rules of heavy metals on aspects of the transportation track, migration characters and mechanism of accumulating and dissipating in lengthways while applying the theory of mass transformation and circulation in the gradually changing process of environment. Based on the experiment on states of heavy metals, the distribution characters of each state in soil profile are studied. After surveying the soil bore in Wudian, we found that pH values changed dramatically and contents of heavy metals increased significantly in the soil stratum from 13.66 to 16.00 meters depth, which is deduced as the major cumulation stratum of contamination. |
| Keywords: | soil heavy metal existing state distribution character |
