摘　　要：城市垃圾的组成和性质是垃圾资源化的重要依据,决定着资源化的途径。以武汉市长山口生活垃圾卫生填埋场的生活垃圾作为研究对象,运用主成分分析法分析了其在2011年9月至2012年8月间各组分的变化情况,得到4个主成分;运用多元回归分析法分析了垃圾含水率、灰分比例与主成分之间的关系,并建立了回归模型。该模型可预测垃圾渗滤液、飞灰的产量,为生活垃圾填埋场与焚烧厂的运营提供参考。The composition and nature of the municipal solid waste are an important basis of the municipal solid waste resource and determines the way of urban waste into resources. The garbage in Wuhan Changshankou Solid Waste Sanitary Landfill Site was taken as an object of study. Adopting mathematics method, analysis of principal component change of domestic waste from September 2011 to August 2012 in the Wuhan landfill site was carried out and four principal components of the garbage were found out. Using multiple regression analysis, it was analyzed the relationship between garbage moisture content, ash ratio with the principal component and established regression model of garbage moisture and waste ash. The model could predict the output of leachate and ash, which also provided reference for the operation of landfills site and incinerators.
