采用2004~2012年哈尔滨市土地利用和能源消耗数据,分析了2004~2012年哈尔滨市主要土地利用方式的碳排放。结果显示:①哈尔滨市2004年碳排放量为361.451万t,2012年碳排放量增长至1875.658万t。②建设用地为主要碳源区,其碳排放占每年碳排放总量的96.98%;林地是主要碳汇区,约占碳汇量的99.90%,其总吸收量约为每年1523.02万t碳;⑧哈尔滨市碳排放强度由2004年的0.681t/hm2L升车2012年的3.534t/hm2,甲均每年增长22.854%;④建设用地碳排放强度2008年以前呈快速增长,2008年以后为缓慢的波动增长:⑤预测2020年建设用地的碳排放量为3558.264万t;碳排放总量为2055.839万t,比2012年上涨180.181万t,年平均增长率为1.15%,增长速度较慢。
The combustion of fossil fuels, followed by changes in land use, is an important source of carbon di- oxide production. More than 80% of carbon emissions come from urban areas, but studies often ignore the rela- tionship between human settlement, the environment and the carbon cycle. Not sufficient attention was devot- ed to studying the role of urban systems in global climate change and in the carbon cycle, particularly car- bon-accounting inventory at the city level. This study explores the land use change that led to changes in car- bon emission intensity in Harbin City from 2004 to 2012. It used land use and energy consumption data to bet- ter understand the effects of carbon emissions in Harbin. In this article, we measured the major land use types and carbon emissions (and absorptions) for the 9 years, and then gave an analysis of the situation of the carbon emission per unit, and discussed the effects of different land use change on carbon emissions. Finally, we esti- mated carbon emission for the year of 2020, providing references on low-carbon development in Harbin. The results showed that: 1) carbon emission was 361.451 x 104t in 2004, and reached 1875.658 ~ 104t in 2011; 2) con- struction was the main type carbon emission area, accounting for 96.987% of the total annual carbon emission; woodland was major carbon sink areas, accounting 99.907% of the carbon sinks, and the total absorption was about 1523.030x 104 t of carbon per year; 3) the carbon emission intensity in Harbin increased from 0.681 t/hm2 in 2004 to 3.534 t/hm2 in 2012; 4) land use for construction showed a rapid growth in carbon emission before the year of 2008, and after that showed a slow and uneven growth; 5) the estimated carbon emission in 2020 will be 3558.264x 104 t for construction land; while the total carbon emissions will be 2055.839x 104, compared to the year of 2012 will increase 180.181 xl04 t, with an annual average growth rate of 1.153%. With contin- ued urbanization and industrialization, carbon emission s
