摘要： 为了研究生活垃圾二级分类模式对垃圾产生特征的影响，以天津市区和西青区水高庄村共310户城乡居民为研究对象，依托已经建立的生活垃圾二级分类模式，将生活垃圾分为可堆腐物、可回收物和有毒有害物3类，重点调查居民生活垃圾的产生强度及分类特征，对城乡居民生活垃圾的产生特点进行比较，并分析生活垃圾的产生强度与经济、文化等因素的关系。结果表明，城市生活垃圾平均产生强度为423.08g/(d·人)，农村生活垃圾平均产生强度为629.89g/(d·人)；可堆腐物产生强度城乡之间呈现显著差异(P=0.00002)，可回收物和有毒有害物的产生强度城乡之间未呈现显著差异，分别为P=0.471和P=0.099。二级分类模式是有效的生活垃圾源头分类模式，对垃圾减量处理起到积极的作用。

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.
