乌鲁木齐市煤炭消费的CO2排放时空分析

摘要

Through calculating CO2 emission from coal consumption in Urumqi during 2001-2009, this study conducted time and space analysis on present status of CO2 emission and CO2 emission from key industrial pollution enterprises in major urban areas. The results showed that： 1. The proportion of coal consumption in total energy consumption has little changed since 2001 and still has high proportion; 2. The CO2 emission from coal combustion increased year by year and the average annual growth rate was 10.84%; In addition, the distribution of CO2 in major urban areas changed significantly, The emission of CO2 from Tianshan district and Toutunhe district were high, while Urumqi county was the minimum. Combined with the current situation in Urumqi, some suggestions are put forward on how to improve the mechanism of reducing greenhouse gas emissions in Urumqi.%通过计算乌鲁木齐市2001-2009年煤炭燃烧CO2排放量，对CO2排放现状及主要城区重点工业污染源企业煤炭消费的CO2排放进行时空分析。结果表明：（1）2001年以来，乌市煤炭在能源消费总量中所占的比重变化不大，占较高比例。（2）煤炭燃烧的CO2排放量逐年增加，年均增长率为10．84％；主要城区CO2的分布变化明显，天山区和头屯河区一直是CO2排放量高值区，鸟鲁木齐县最低。结合乌市CO2排放现状及面临问题，提出减排对策，从而为健全乌市温室气体减排机制提供有力支撑。
