National forest inventory materials and data from China Forest Ecosystem Location Research Network (CFERN) were obtained for estimating four periods of carbon storage of Bamboo forest ecosystem from 1977 to 2003 in China. The spatial and temporal patterns, vertical distribution and potential carbon storage of the bamboo forest ecosystem were analyzed. The results showed that carbon storage of Chinese bamboo forest ecosystem was 537.6 Mt C during 1977 and 1981, 598.61 Mt C during 1984 and 1988, 710.14 Mt C during 1994 and 1998, and 837.92 Mt C during 1999 and 2003. It showed that the carbon storage was increasing during that time. Zhejiang, Jiangxi, Fujian, Hunan, Guangdong and Sichuan were the major carbon pools in China, with the percentages of carbon storage between 80.04 and 83.13 percent in all. The percentages of carbon storage of vegetation, litter, and soil were between 23.85 and 24.48 percent, between 0.92 and 0.96 percent, and between 74.56 and 75.23 percent respectively. Therefore, it is concluded that the carbon storage in different layers were similar vertically. Carbon storage was 837.92 Mt C from 1999 to 2003, and it will be increased to 947.54 Mt C after one age period with a rate of 54.81Mt carbons stored in ecosystem every year. 展开更多
