| 摘 要： | 土壤元素的缓变型地球化学灾害具有重要危害。基于缓变型地球化学灾害数学模型,分别研究了合肥大兴镇地区和义城镇地区土壤中Cu元素的缓变型地球化学灾害特征并进行了对比。研究结果显示,大兴镇地区土壤中Cu元素有污染物可释放总量TRCPCu→污染物有效量CuE+C释放转化的趋势,其缓变型地球化学灾害模型为y=0.005 6x3-0.436 1x2+11.28x-90.803,约38%面积的土壤具有爆发Cu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。而义城镇地区土壤中Cu元素还不具有爆发缓变型地球化学灾害的可能性,这与该区以农业和养殖业为主有关。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: | Delayed geochemical hazard(DGH) of soil elements in soil will do serious harm to the environment.Base on the mathematical model of DGH,DGH characteristics of Cu element in the soils of Daxing Town and Yicheng Town of Hefei were studied and compared.Results show that Cu element in the soil of Daxing Town tends to shift from release of TRCPCu(total releasable content of Cu element) to that of CuE+C(effective content of Cu element),and its DGH model was y = 0.005 6x3-0.436 1x2 + 11.28x-90.803.In the soil of ab... |
