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 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.
