中国森林生态系统中植物固定大气碳的潜力

In the field of global climate change study, scientists have paid an great attention to identify CO 2 sources and sinks in the terrestrial ecosystems. It has been predicted that the forest ecosystems would become a CO 2 sink because of its huge capacity for storing carbon. Based on our previous study on the biomass of forest ecosystems in China, this study is to analyze the temporal change in carbon storage of forest ecosystems, and estimate the difference between actual and potential carbon storage of forest ecosystems in China. It is showed that the actual carbon storage is only 44.3% of the potential one in the forest ecosystem of China
