摘　　要：兴仁县境内的煤矿是黔西南典型的高砷煤矿区之一。通过对矿区范围内土壤表土和沉积物中砷的调查研究表明，土壤表土和沉积物中As的含量分布范围广泛，分别为5．28～234．14mg／kg和20．68～219．14mg／kg。这些分布特点与该区高砷地质地球化学背景有关外，还与煤炭资源开发有很大的关系。煤矿水灌溉的农田土壤袁土和水系沉积物中As的积累已经显现出来。因此，矿区煤矿开发引起的土壤表土／沉积物中砷的积累应该得到高度重视。The coal area in Xingren County is one of the most representaive areas of high arsenic coal in southwestern Guizhou Province. The arsenic concentrations of surface soils and sediments in the coal area were analyzed. It is concluded that the contents of As in surface soils and sediments are within the ranges of 5.28- 234.14 mg/kg and 20.68- 219.14 mg/kg, respectively. The arsenic concentration characteristics in surface soils and sediments are not only concerned with high arsenic geochemistry background, but also with mining activity. The results indicated that As accumulation in surface soils and sediments resulted from coal mining activity, therefore, more attention should be paid.
