摘　　要：在分析城市生活垃圾混合收集和分类收集优缺点的基础上,总结了我国试点城市垃圾分类收集存在的问题。根据垃圾分类是一个熵减过程,从社会进步和社会分工的角度说明垃圾源头分类收集比混合收集后再分类需要输入更多的能量,付出更多的劳动时间,因而城市生活垃圾应采用混合收集后由专门工作人员分类,而不是公众的源头分类。Relative merits of different collection and classification mode of municipal solid waste （MSW） were analyzed, and results indicated that separate collection of MSW need more energy input or labor time than classification after mixing collection because MSW classification is a process of entropy decreasing （PED）. As far as social progress and social division of labor is concerned, classification after mixing collection of MSW should be adopted because of high efficiency, while separate collection not be adopted because of poor efficiency.
