摘要
本文应用基于环境容量的基尼系数法定量评价我国主要化石能源消费的CO2排放空间公平性。结果表明以森林面积为参照标准,CO2排放基尼系数为0.7249,处于"高度不平均"区间内,空间不公平因子主要为中东部发达城市和经济大省;假设各省林业用地的80%转换为森林,CO2排放基尼系数则降低为0.7233,省际碳排放与环境容量高度不均衡格局及不公平因子没有太大变化。从节能减排、植树造林和建立碳交易市场等视角降低碳排放分配基尼系数,是提高我国省际之间碳排放空间相对公平的重要思路。
In this paper,the Gini coefficient based on environmental capacity is used to evaluate spatial equalities of CO2 emitted from consumption of major fossil energy in China.The results show that： the Gini coefficient of CO2 emissions is 0.7249,and within the range of ＂high degree＇s non-average＂,taking the forest area as the reference standard.The main key inequalities factors are developed for cities and large-scale economic provinces in the central and eastern regions.The Gini coefficient reduces to 0.7233,assuming 80% of forest land converting into forest,the co-ordination situation of inter-provincial CO2 emissions and environmental capacity and key inequalities factors do not change greatly.In order to promote the relative inter-provincial equalities,it is necessary to reduce emissions,plant tree and establish carbon trading market,if implementing total amount control on CO2 in the future.
