以某金矿区农田土壤重金属Pb为研究对象，分别以2004和2012年采集样品的测试结果作为计算农田土壤重金属Pb累积速率的依据，以2004-2012年作为计算时间区间，以农田土壤重金属Pb的累积速率为研究内容，采用对比分析方法，分析区域Pb的累积速率特征，阐明人类工程活动极大地影响着农田土壤重金属Pb的累积过程。研究结果表明，全区农田土壤Pb平均累积速率为31.8mg/kg· a-1。选取选矿厂、冶炼厂、尾矿库、污水灌溉区、车载尾矿弃渣等典型污染源，对周边农田土壤Pb累积的时空变化特征进行分析。结果显示，选矿厂对农田土壤Pb累积的影响最大，其周边农田土壤Pb累积速率相当于全区Pb累积速率的4倍，该结论对防治重金属污染及保障人体健康具有实际指导意义。

With heavy metal Pb in farmland soil of a gold mining area as the research object, the test results of some samples collected in 2004 or 2012 as the basis for computing Pb accumulation rate, and the period of 2004-2012 as the calculation interval, the authors mainly studied the accumulation rate of Pb. Comparative analysis and sum-average arithmetic method were used to analyze the fea-tures of the Pb accumulation rate, and the results show that the Pb accumulation process mainly resulted from human activities of mineral exploitation. The average accumulation rate of the farmland soil Pb in the whole area was 31.8mg/kg. Choosing some pollu-tion sources such as ore dressing plant, smeltery, wastewater irrigation area, tailings storehouse and both sides of highway, the authors analyzed the temporal-spatial accumulation features of the pollution sources of heavy metal Pb near farmland soil. The results indicate that the Pb accumulation contribution of the ore dressing plant to the farmland soil was the biggest. Its accumulation rate was four times that of average accumulation rate of the whole area. The results obtained by the authors have important significance for prevent-ing and controlling the heavy metal pollution and protecting human health.
