| 摘 要： | 陆地生态系统在全球碳循环动力学中的作用受到越来越多的注意。目前中国森林覆盖率为1392% , 到本世纪末全国森林覆盖率将达到15% , 对全球碳平衡具有重要作用。但是,由于我国碳循环的基础研究比较落后,致使我国陆地生态系统的碳储量和净第一性生产力 （NPP） 碳量还没有被准确确定, 而且陆地生态系统的碳通量估计存在较大差异。 |
| 关 键 词： | 自然植被 空间分布 碳密度 碳储量 |

| Abstract: | The role of terrestrial ecosystems on global carbon cycle dynamics is more and more noticed. At present, the rate of forest cover in China is 13 92% and it will be 15% at the end of twentieth century. This is more contribued to the balance of global carbon. However, carbon fluxes of terrestrial ecosystems are not accurately defined in China, and people do not recognize enough its importance to global climate change. Not defining accurately the carbon storage of Chinese vegetation and NPP has caused a large difference in carbon flux of terrestrial ecosystems in China. This paper adopts measured data in site and appliys technique of GIS, to acquire cover data of natural vegetation in China, and to calculate carbon and carbon density of every type of natural vegetation. The study establishs a database of terrestrial natural vegetation biomass in China. Meanwhile, we have researched simply the spatial distribution of terrestrial natural vegetation carbon storage in China Then, forest is the main body of natural vegetation in carbon cycle. This paper can provide basic data and analysis methods for global change research and scientific support for policy determination of CO 2 emission in China. |
