污染物排放量增长与经济增长的脱钩本质之一就是污染物排放减量化直至去污化,实现生态与经济的共生。选择废水、化学需氧量、氨氮、二氧化硫和烟尘作为污染物指标,GDP、工业增加值和消费支出作为经济指标,进行脱钩分析。结果表明:1998-2010年,污染物排放量与经济增长脱钩状态总体上处于增长弱脱钧和强正脱钩,但是部分污染物排放量脱钧状态出现短暂的恶化情形。结构性分析发现:生活领域的废水、化学需氧量和氨氮对废水、化学需氧量和氨氮排放总体脱钩影响显著;工业S02排放直接决定着S02总量脱钩状态;生活烟尘对烟尘脱钩状态产生扰动性影响。
Essence of decoupling between pollutant emission growth and economic growth is the reduction of pollu- tant emission, even none-pollution,and achieving the symbiosis between ecology and economy. The paper chose the e- mission of waste water,chemical oxygen demand (COD), ammonia nitrogen (AN), sulfur dioxide (S02) and flue dust as the pollutant indicator, and chose GDP, industrial added value, consumption expenditure as the economic indicator, and then made decoupling analysis. According to the results, decoupling condition is weak expansive decoupling and pos- itive strong decoupling by and large, but part of decoupling condition temporarily worsens during 1998-2010. On struc- tural analysis, the waste water, COD and AN from household have positive effect on the whole pollutant. The emission of industrial SO2 directly determines decoupling of the whole SO2. The household flue dust gives rise to disturbance influ- ence on the whole decoupling.
