摘要: 论文从人-地结合视角看待碳移动问题,根据2001—2009 年遥感数据和能源数据,分别计算各省碳排放和碳吸收量,引入流动比率,从而划分出高碳源地、低碳源地和碳汇地,结合标准差椭圆进一步分析人-地碳源汇系统离散和聚集趋势,进而得出人-地碳源汇系统空间格局演变及其特征。研究表明:①高碳源地主要集中在华北地区和上海地区,作为高碳源地的华北地区呈逐步向外扩张趋势,低碳源地主要在华东地区、华中地区和广东地区,呈现不断向西、南方向扩散趋势,碳汇地主要在西北、东北和西南地区;②高碳源地从点状式分布逐步向外扩散,到2009 年呈现华北两端聚集,上海突出的类三角形结构,低碳源地呈现华中和华东两端聚集,广东、吉林突出的类四边形结构,而碳汇地基本是在外围包围低碳源地,人-地碳源汇系统呈现逐级由上至下态势,高碳源地不断由内向外扩散,低碳源地不断转变成高碳源地,同时碳汇地也不断转变成低碳源地;③2001—2009 年高碳源地标准差椭圆位于华东和华北地区,分布格局呈西北—东南格局,范围在2005 年之前基本不变,2005 年之后逐步扩大;2001—2009 年低碳源地标准差椭圆主要集中在华东和华北地区,分布格局从“东北—西南”到“西北—东南”,再到“东北—西南”,最后又回到“西北—东南”,低碳源地在主轴和辅轴上分布不断分散,2001—2003 年间变化最大,2003 年之后变化幅度减少;2001—2009 年期间碳汇地系统呈东北—西南分布格局,且椭圆整体位于中国东部和中部地区,碳汇地系统在此期间并没有出现较大的波动。

Abstract: This paper has tried to provide further insight into the carbon flow problem from the perspective of human-nature system. Based on energy data and remote sensing data from 2001 to 2009, we calculated the carbon sequestration and carbon emission of different provinces; by introducing the flow ratio, the high carbon source area, the low carbon source area and the carbon sink area were divided; besides, with the standard ellipses we also analyzed the diffusioncoalescence tendency of the human- nature carbon source- sink system to uncover its patterns and dynamics. Results show that: 1) The high carbon source area is mainly in northern China and Shanghai with a diffusion tendency; the low carbon source area is mainly in eastern China, central China and Guangdong with a diffusion tendency to the west and the south; the carbon sink area is mainly in northwestern China, northeastern China and southwestern China. 2) The high carbon source area has expanded from a point to form a triangle structure between northern China and Shanghai; the low carbon source area shows a quadrilateral structure between central China, eastern China, Guangdong and Jilin; the carbon sink area encompasses the low carbon source area. The high carbon source area has a diffusion tendency from inside to outside. The low carbon source area has continually changed into the high carbon source area while the carbon sink area has continually changed into the low carbon source area. 3) The standard deviation ellipse of the high carbon source area is in eastern China and northern China and shows a northwest-southeast pattern, whose range remained unchanged before 2005 and then expanded. The standard deviation ellipse of the low carbon source area is mainly in the region of eastern China and northern China and its pattern has changed as a sequence of northeast-southwest, northwest-southeast, northeast-southwest, and northwest-southeast. The low carbon source area distribution on the main direction and the horizontal direction has continually dispersed with the greatest change from 2001 to 2003 and little change after that. The carbon sink system represents a northeast-southwest pattern and the ellipse is mainly in eastern China with little change of axis, which shows the stability of the carbon sink area pattern during this period.
