参照资源消耗及废物排放与经济增长的定量表达式-IGT方程和IGTX方程,分别推导出资源脱钩指数和二氧化碳排放指数方程.根据脱钩指数,将二氧化碳排放与GDP脱钩程度分为绝对脱钩、相对脱钩和未脱钩三种程度,并构建了假设相对脱钩和假设绝对脱钩区间.以辽宁省1995-2012年间二氧化碳排放量和GDP增长量为对象,分析了二者的脱钩关系.研究发现,除了1997和1999年二者处于相对脱钩状态,其余年份均未脱钩.运用假设脱钩区间模型,分别计算达到相对脱钩和绝对脱钩状态的二氧化碳年排放理想值,并与现值进行比较,得到各年节能减排的压力值.研究结果表明:相对脱钩的压力相对较小,减排压力在0-1671万t之间,占基准年碳排放量的0%-12.23%;绝对脱钩的压力较大,减排压力在320.77-4899.84万t,占基准年碳排放量的2.35%-23.94%.
Based on the quantitative expressions-IGT equation and IGTX equation of resource consumption, waste discharge and economic growth, the index of decoupling of resources and the index of carbon dioxide emission were deduced respectively.According to the decoupling index, the degree of decoupling of carbon dioxide emissions and GDP was divided into absolute decoupling and relative decoupling And did not decoupled three kinds of degree and constructed the assumption that the relative decoupling and the assumption of absolute decoupling interval.Considering the carbon dioxide emissions and GDP growth in Liaoning Province between 1995 and 2012, the analysis of the decoupling between the two studies found that, in addition to 1997 and In 1999, the two were relatively decoupled, and the rest of the year was not decoupled. Using the assumed decoupling interval model, the annual emissions of carbon dioxide reaching relative decoupling and absolute decoupling were calculated respectively and compared with the present value to obtain the annual energy saving and emission reduction The results show that the relative decoupling pressure is relatively small, the emission reduction pressure is between 0 and 16.71 million tons, accounting for 0% -12.23% of the baseline annual carbon emissions; the pressure for absolute decoupling is relatively large, and the emission reduction The pressure is 320.77-4899.84 million tons, accounting for 2.35% -23.94% of the base year’s carbon emissions.
