摘　　要：从定性研究逐步向定量化分析发展,是土壤DDT残留时间研究的必然趋势。初步探讨了土壤中DDT残留时间的定量表征,设计出归一化的DDT残留时间指数(NRTI)作为定量表征土壤DDT残留时间的方法之一。根据对天津土壤中残留DDT的采样监测结果的计算和分析,发现NRTI在表征DDT的残留时间问题上,相对于传统方法有一定的改进。The transfer from qualitative research to quantitative analysis showd the inevitable tendency of research on the residual age index of dichlorodiphenyltrichloroethane(DDT) in soils.The quantitative token of the residual age index of DDT in soils was primarily discussed,and the normalized residual time index(NRTI) of DDT was designed as one of the methods.Based on the calculation and analysis on the sampling outcome of the soils in Tianjin,it revealed that NRTI had an obvious advantage over the traditional methods on assessing residual time of DDT and it's metabolic situation.
