Obviously, the optimization management in middle-sized or small cities of China is very necessary. The basic characteristics of municipal solid waste generated in middle-sized or small cities of China are put forward in the paper. The total amount of municipal solid waste generated in middle-sized or small cities is significantly less than that in large cities. The amount of garbage is about 1 kg per capita and year. In the garbage, inorganic material is more than organic material, the combustible less than incombustible and the amount of uncompostable garbage more than the amount of garbage that can be disposed for composting. The value of heat of garbage is about 800 kal/kg.

通过总结，我国中小城市生活垃圾的基本特点为：各城市的生活垃圾产生量相对较小，人均生活垃圾产生量大约在1kg/d左右；垃圾组分中以煤渣、灰土为主的无机成分含量过高，可回收物质成分含量很低，不可燃成分多于可燃成分，不可堆腐成分多于可堆腐成分，垃圾热值大约在800kal/kg左右；并且在我国，南方城市与北方城市，经济发达城市与欠发达城市之间的生活垃圾产生量与组成也存在着明显的地区差异。
