摘要 城市生活垃圾在填埋处理过程中会向大气排放甲烷,增加大气中温室气体的含量,对全球气候变化产生一定的影响.采用数学统计方法,通过对中国城市生活垃圾清运量的变化趋势及影响因子分析,证实了城市生活垃圾的产生与非农业人口数量、国民经济发展水平、城市建成区面积以及城市人口数量和城市数量等因子有较好的相关关系.通过对代表城市的垃圾成分进行调查分析,结合历史资料,得出中国城市生活垃圾成分有区域和时间变化特征:南方城市和大城市的有机物与可回收物含量高于北方城市和中小城市,而无机物含量则相反;有机物含量随时间基本上呈上升趋势,无机物含量则呈下降趋势,但近些年有机物和无机物含量均逐渐趋于平稳,变化不是很大. The municipal solid waste treated in landfill can emit the methane to the atmosphere and increase the greenhouse gas concentration in the atmosphere, which has influences on the global climatic change. The statistic method was used to analyze the correlation of generating amount of municipal solid waste (MSW) with other driving factors, such as non-agriculture population, GDP and area of built district as well as the numbers of cities, etc. Based on the historical data analysis, survey in selected cities and calculation of MSW, the characters and trends of MSW were studied. The results show that the organic substance content and reusable material of MSW in south or big cities are higher than in north or medium and small cities, but the inorganic substance content is reverse. The organic composition has an increasing trend and the inorganic composition has a decreasing trend, but the trends change to steady gradually and the composition of municipal solid waste stabilizes in the same level in recent years.
