我国电力行业CO_2排放系数和CO_2排放时空特征

Temporal and Spatial Characteristics of CO_2 Emission and Its Coefficient from Power Industry in China

为了改善与优化我国现存的能源消费结构,需要开展我国能源消费和能源消费CO2排放等方面的研究。使用1980—2007年期间逐年发电量、单位发电煤耗等统计数据,计算了不同时期我国单位发电CO2排放系数。其中,1980年电力行业的单位发电CO2排放系数为1.07kg/kW.h,2007年为0.78kg/kW.h。基于省级电力消费数据,结合不同时段的单位发电CO2排放系数,得出各地区单位生产总值电耗CO2排放系数,分析了我国电力消费所致的温室气体排放的省际空间特征。

It was important to research on energy consumption and its C02 emissions in China for improving Chinese energy consumption structure. This paper, using annual generated energy and coal consumption of unit power generation from 1980 - 2007 years, the C02 emissions coefficients of unit power for different times were obtained in China. The C02 emissions coefficients of unit power were 1.07kg/kW-h and 0.78 kg/kW-h respec- tively in 1980 and 2007. Based on the data of provincial power consumption and its C02 emissions coefficient of unit power in different times, C02 emission coefficients of unit GDP（gross domestic product）power consumption could be obtained for different regions in China. Otherwise, the authors analyzed the provincial spatial feature of greenhouse gas emission due to power consumption in China.
