摘要: 基于缓变型地球化学灾害数学模型，对合肥大兴镇地区土壤中Pb元素的缓变型地球化学灾害特征进行研究.结果显示，研究区土壤中Pb元素有TRCPPb→PbE+C释放转化的趋势，土壤面积约11%具有爆发Pb缓变型地球化学灾害的可能性，这与大兴镇是合肥的工业重镇有关.同时，土壤元素缓变型地球化学灾害的研究对土壤重金属污染预警具有重要的意义.

Abstract: Base on the mathematical model of delayed geochemical hazard (DGH), the DGH characteristics of Pb element in the soil of Daxing Town, Anhui Province is studied. The result shows that the Pb element in the soil of Daxing is releases in the trend of TRCPPb→PbE+C. About 11% of soil area in Daxing has the possibility to break out DGH of Pb element, because the Daxing Town is an important industry town of Anhui Province. The study on DGH is of great significance for early-warning of the hazard of heavy metal elements in soil.
