摘　　要：基于缓变型地球化学灾害数学模型,研究了合肥市梁园镇地区土壤中Cu、Zn元素的缓变型地球化学灾害特征。研究结果显示,梁园镇地区土壤中Cu元素有TRCPCu→CuE+C释放转化的趋势,约89.97%面积的土壤具有爆发Cu缓变型地球化学灾害的可能性,Zn元素也有TRCPZn→ZnE+C释放转化的趋势,约57.21%面积的土壤具有爆发Zn缓变型地球化学灾害的可能性,这可能与该区的油菜种植有关。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。Based on the mathematical model of delayed geochemical hazard （DGH）, the DGH characteristics of Cu element and Zn element in soil of Liangyuan town in Hefei area were studied. The result showed that the Cu element in soil of Liangyuan town had the releasing trend of TRCPCu→CuE＋C, about 89.97% area of soil in Liangyuan town has the possibility to break out DGH of Cu element, and the Zn element in soil of Liangyuan town also had the releasing trend of TRCPZn→ZnE ＋C, about 57.21% area of soil in Liangyuan town has the possibility to break out DGH of Zn element. It might be attributed to the growth of cole in Liangyuan town probably. The studies of DGH are of great significance for early-warning of the hazard of heavy metal elements in soil.
