From the viewpoint of man the earth system, garbage is characterized by sociality, temporal and spatial differentiation and limitation and other features, which imply that the garbage research being involved with natural science and social science should not only focus on the natural features but also on the social features. Compared to some developed cities, the material composition of garbage in Changchun is typically characterized by high moisture content, low combustion value and minor recyclable materials. Concentration, cycle shaping and self similarity characterize the garbage distribution. The tracing investigation on 683 households ten times shows that three fourths of the total garbage yield in Changchun is derived from non domestic units and that the attention of garbage management, especially source reduction, should be focused on the non domestic units. The GM(1,1) prediction model has been set up and the prediction result shows that the amount of garbage yield of Changchun in 2004 will be up to 1,500,000 tons. Investigation of environmental consciousness to garbage problems have been carried out. Based on the above characteristics of garbage, the disposal countermeasures of Changchun garbage have been suggested.展开更多
