摘要：

Biometric inventories for 25 years, from 1983 to 2005, indicated that the Jianfengling tropical mountain rain forest in Hainan, China, was either a source or a modest sink of carbon. Overall, this forest was a small carbon sink with an accumulation rate of (0.56 +/- 0.22) Mg C ha(-1)yr(-1), integrated from the long-term measurement data of two plots (P9201 and P8302). These findings were similar to those for African and American rain forests ((0.62 +/- 0.23) Mg C ha(-1)yr(-1)). The carbon density varied between (201.43 +/- 29.38) Mg C ha(-1) and (229.16 +/- 39.2) Mg C ha(-1), and averaged (214.17 +/- 32.42) Mg C ha(-1) for plot P9201. Plot P8302, however, varied between (223.95 +/- 45.92) Mg C ha(-1) and (254.85 +/- 48.86) Mg C ha(-1), and averaged (243.35 +/- 47.64) Mg C ha(-1). Quadratic relationships were found between the strength of carbon sequestration and heavy rainstorms and dry months. Precipitation and evapotranspiration are two major factors controlling carbon sequestration in the tropical mountain rain forest.
