Abstract: In order to investigate the influence of secondary classification pattern on waste generation features, the author took 310 urban and rural households at urban areas and Shuigaozhuang Village, Xiqing District of Tianjin as the research objects, based on the constructed secondary classification pattern of domestic waste, classified domestic waste into 3 groups: compost, recycles and toxics. The author focused on waste generation strength and classification features, made a comparison on waste generation features between rural and urban residents, and analyzed the relation between waste generation strength and economic and cultural factors. The results indicated that the average generation speed of urban domestic waste was 423.08 g/(d·capita), and that of rural domestic waste was 629.89 g/(d · capita), there was significant difference between rural and urban compost generation strength (P=0.00002), while the generation strength of recycles and toxics between urban and rural areas had no significant difference (P=0.471 and P=0.099, respectively). Secondary classification pattern was an effective source classification mode for domestic wastes and had positive effects on waste reduction and treatment.
