摘要
采用二氧化碳排放当量分析(CEEA)方法计算了中国除港澳台外的31 个省级行政区涉及水资源开发、配置、利用与保护4 个维度的16 种水资源行为二氧化碳排放当量(CEE),并基于Dagum基尼系数探究了中国水资源行为CEE的空间非均衡性及其来源.结果表明:2020 年中国水资源行为CEE总量为 13 819.84 万 t,开发、配置、利用与保护 4 个维度水资源行为 CEE 总量分别为21297.68 万、4371.45 万、-3141.71 万、-8707.58 万t;水资源行为CEE整体呈现出由东向西递减的空间分布规律,江苏和广东是水资源行为CEE最大的省份;多数水资源行为CEE具有较强的空间非均衡性,其中水力发电行为CEE的Dagum基尼系数为0.73,其CEE空间非均衡性最强,地区间净值差异是水资源行为CEE空间非均衡性的主要贡献因素.
Abstract
The carbon dioxide emission equivalent analysis(CEEA)method was used to calculate the carbon dioxide emission equivalent(CEE)of water resource behaviors in China's 31 provincial administrative regions excluding Hong Kong,Macao,and Taiwan,involving 16 kinds of water resource behaviors in four dimensions,including water resource development,allocation,utilization,and protection.The spatial disequilibrium of CEE of water resource behaviors in China and its sources were explored using the Dagum Gini coefficient.The results show that the total CEE of water resource behaviors in China was 138.1984 million t in2020,and the total CEEs of water resource behaviors in the four dimensions of development,allocation,utilization,and protection were 212.9768 million,43.7145 million,-31.4171 million,and-87.075 8 million t,respectively.CEE of water resource behaviors generally showed a decreasing spatial distribution pattern from east to west,and Jiangsu and Guangdong had the highest CEE of water resource behaviors.CEE of most water resource behaviors showed strong spatial disequilibrium,and the Dagum Gini coefficient of CEE for hydropower behavior was 0.73,showing the strongest spatial disequilibrium of CEE.The inter-regional net value difference was the main contributing factor to the spatial disequilibrium of CEE of water resource behaviors.
