南京市工业系统资源环境减量投入分析

本文将物质减量图解应用于工业系统的资源环境减量投入上,对南京市工业系统1986～2004年的资源环境的使用强度和减量化水平进行了计算和分析。结果表明,南京市工业系统的资源环境使用强度在评价期间逐年降低,2004年的工业用水、能源消耗、废水排放、废气排放和“固废”排放的强度分别为1986年的18.14%、15.14%、4.36%、14.95%、15.72%;在评价期间南京市工业系统只有工业废水实现了绝对减量排放;而水耗、能耗、废气排放和“固废”排放四项指标均没有实现绝对减量,致使在此期间南京市工业系统水耗增加了384100.66万吨,能耗增加了1409.32万标准吨煤,废气排放量增加19852018.00万立方米,“固废”增加排放603.26万吨。

Analysis on The Reducing Input of Resources and Environments of Industry System in Nanjing City

This paper applies the illustration of dematerialization to reducing resources and environmental inputs of industrial system.The use intensity and reducing level of resources and environments of industrial system in Nanjing city from 1986 to 2004 are calculated and analyzed,which demonstrate a yearly decline.In comparison,the indicators of water consumption,energy consumption,wastewater discharge,waste gas emissions and solid wastes discarded in 2004 were 18.14%,15.14%,4.36%,14.95% and 15.72% respectively,of that in 1986.During the evaluation period,all of the indicators,except for the industrial wastewater,did not reduce their magnitude.Actually the water consumption,energy consumption,waste gas emission and solid wastes discarded increased by 3.8410066 billion tons,14.0932 million tons of standard coal,198.52018 billion cubic meters and 6.0326 million tons,respectively.
