Using the MSW (municipal solid waste) sampling and analysis methods, the composition characteristics of MSW in south China were investigated. The results showed that: the average MSW bulk density was 0.22 x 10(3) kg x m(-3), the percentages of water, ash and combustible were 55.0%-66.9%, 18.6%-30.3% and 69.7%-81.4%, respectively. The organic contents were 50.1%-58.0%. The waste low caloric value (wet base) ranged 6570-9652 kJ x kg(-1), and the average of waste low caloric value(wet base) was 8272 kJ x kg(-1), which was higher than the recommended value of World Bank(7000 kJ x kg(-1)). The percentage composition of MSW was: 39.8%-53.3% kitchen waste garbage, 16.5%-33.4% rubber and plastics, 5.61%-7.95% paper, 1.14%-5.16% textile products, 2.49%-5.12% bamboo products, 1.10%-1.47% glass, 5.86%-7.57% mixed materials, 2.46%-6.73% dust, 0.1%-0.32% metal, and 0.4%-0.69% ceramic. The correlation analysis and factor analysis showed that: the high proportions of textile, rubber and plastics, paper, and combustible materials had a positive effect on the MSW incineration, while the high proportions of kitchen waste garbage, glass, MSW bulk density, ash, water content and dust had a negative effect on the MSW incineration.
采用城市生活垃圾（MSW）采样与分析方法，对中国南方城市生活垃圾的组成特性进行了调查。结果表明：城市生活垃圾平均堆积密度为0.22×10³ kg·m⁻³，水分、灰分和可燃物的百分比分别为55.0% - 66.9%、18.6% - 30.3%和69.7% - 81.4%。有机含量为50.1% - 58.0%。垃圾低位热值（湿基）范围为6570 - 9652 kJ·kg⁻¹，垃圾低位热值（湿基）平均值为8272 kJ·kg⁻¹，高于世界银行推荐值（7000 kJ·kg⁻¹）。城市生活垃圾的百分比组成为：厨余垃圾39.8% - 53.3%，橡胶和塑料16.5% - 33.4%，纸张5.61% - 7.95%，纺织品1.14% - 5.16%，竹制品2.49% - 5.12%，玻璃1.10% - 1.47%，混合物料5.86% - 7.57%，灰尘2.46% - 6.73%，金属0.1% - 0.32%，陶瓷0.4% - 0.69%。相关性分析和因子分析表明：纺织品、橡胶和塑料、纸张以及可燃物比例较高对城市生活垃圾焚烧有积极影响，而厨余垃圾、玻璃、城市生活垃圾堆积密度、灰分、水分含量和灰尘比例较高对城市生活垃圾焚烧有负面影响。
