摘要
介绍了城市生活垃圾的主要处理方法及目前中国城市生活垃圾的处理现状,通过实际调研和统计分析表明:中国城市生活垃圾的处理方式主要以填埋为主,占总处理量的95%以上;卫生填埋处理能力较低,处理水平参差不齐,有较大的区域性差异.基于城市生活垃圾清运量与国民经济发展水平、非农业人口数量等驱动因子相关,建立了城市生活垃圾清运量预测模型,并利用该预测模型预测了不同情景下未来中国城市生活垃圾清运量,比较分析了不同模型的预测结果,表明非农业人口预测结果与GDP和人均GDP预测结果有一定的差异,非农业人口预测结果更接近于中国的实际情况.
The treatment methods of municipal solid waste in China were introduced briefly, and current status of municipal solid waste treatment and its trend were studied. The results show that the major treatment method in China is landfill, with the treatment ratio accounting for 95% of the total. The capacity of sanitary landfill is lower, and there exist big differences in treatment levels all over China, so the regional difference exists in municipal solid waste treatment. Based on the correlations of transportation amount of solid waste with other driving factors, such as GDP, per capita GDP and non-agriculture population, the estimating models were built. The models were used to forecast future municipal solid waste generating amount in different scenarios. The forecasting result of non-agriculture population is more close to reality than GDP or per capita GDP-based models.
