摘要： 基于生态足迹成分法的基本原理,构建了度量城市固态垃圾环境压力的生态足迹与排放强度计算模型.应用该模型对沈阳市1990~2005年垃圾排放的生态足迹进行了计算.结果表明,垃圾排放的生态足迹几乎全部来源于吸收垃圾降解产生的温室气体所需要的森林面积,1990年约20×104hm2,2005年约15×104hm2.另外,对沈阳市1990~2005年固态垃圾的产生与排放强度的分析表明,沈阳市万元GDP(以二、三产业GDP的2000年不变价计)的垃圾产生量由1990年的1.24 t降到2005年的0.36 t,年下降率为7.87%;同期万元GDP的垃圾排放量从0.89 t降到0.17 t,年下降率为10....

Abstract: Based on the componential method of ecological footprint (EF) computation, a model was developed to calculate the EF of urban solid waste so as to quantify its environmental pressure. With the model applied, the EF of urban solid waste in Shenyang was calculated from 1990 to 2005. The results indicated that almost the entire EF results from the equivalent forest area required for absorbing the greenhouse gas from waste's degradation, i.e., about 200000 hm2 in 1990 and 150000 hm2 in 2005. In addition, the quantity of solid waste and its disposal intensity were analyzed. The results showed that the quantity was 1.24 t in 1990 and 0.36 t per RMB 10000 of GDP in 2005 with an annual reduction rate of 7.87%, and the disposed quantity of waste was 0.89 t in 1990 and 0.17 t in 2005 with an annual reduction rate of 10.61%, where the GDP was calculated at the fixed price of the secondary and tertiary industries in the city in 2000. Thus, with respect to the quantity and disposal of solid waste, the environmental efficiency in Shenyang's economic development was rising at a relatively high speed.
