摘要:
运用文献分析法、归纳总结法、统计分析法测算了重庆市12 a来不同土地利用类型的碳排放，分析了变化特征并对其时空差异类型进行了划分。结果表明：（1）重庆市碳汇大于碳源，碳排放总量表现为碳吸收，1997—2008年碳吸收能力在波动中呈下降趋势，到2008年重庆市总碳吸收量为14 570.85万t；（2）各类用地中，林地为主要的碳汇，建设用地为主要的碳源，建设用地碳排放增长幅度最快，年增长率为9.89%，应控制碳排放的快速增长；（3）地均建设用地碳排放和单位产值碳排放强度较高，碳排放强度与经济发展水平呈正相关关系；（4）土地利用碳排放效应受多种因素限制，能源消耗是碳排放主体；（5）40个区县的土地利用碳排放效应在空间分布上存在较大差异，应实施差别化的碳减排调控策略，引导城市低碳发展。
Abstract:
The purpose of this paper is to calculate the carbon emission of land use from 1997 to 2008 in Chongqing City, and analyze the characteristic of effect of land use on carbon emission, and divide the spatiotemporal difference types. The employed methods are documentation, inductive analysis and statistical analysis. The results indicate that:(1) carbon sink was greater than carbon source, the characteristic of carbon emission expressed as carbon absorption. the carbon absorption capacity took on the downward trend from 1997 to 2008, the total carbon uptake was -14 570.85 million tons in 2008 in Chongqing CIty, the government should control the rapid growth of carbon emission; (2) in the different types of land use, woodland is the main carbon sink and construction land is the main carbon source, the carbon emission of construction land grows fastest and increases by 9.89%; (3) the carbon emission per unit area of construction land and carbon emission per unit output value are higher, the emission intensity is found to be positively correlated with the level of economic development; (4) effects of land use on carbon emission are depended on many factors, energy consumption is the main source of carbon emission; (5) effects of land use on carbon emission of the forty counties are quite different, in order to achieve low-carbon-targert-oriented city, different strategies should be used for carbon emission reduction.
