摘要
森林生态系统在陆地生态系统碳循环中占有十分重要的地位。综述了中国森林碳储量的时间变化规律和空间变化规律,总体上随着时间的推移,中国森林面积和碳储量都呈现出增长趋势,起着"汇"的作用;中国森林的植被碳密度有从东南向东北和西增加的趋势,并与人口密度负对数显著相关。此文分析了温度与降水、CO2浓度及土地利用变化等主要影响因子,还对今后碳密度的研究方向作了思考。
Forest ecosystem plays an important dominant role in carbon cycle of terrestrial ecosystem. The paper summaries the spatial and temporal variation laws of carbon storage in Chinese forest. In general, the area and carbon storage of the forest both increase with the time passing by, which play a role of sink. The forest carbon density in China has the tendency of increase from southeast to northeast and west, and there is a significant negative logarithm correlation between carbon density and population density. The influence of main factors such as temperature, precipitation, CO2 concentration and land use change are also analyzed. Based on a brief review of forest carbon storage, the author puts forward several research areas that should be strengthened in the near futures in China.
