摘要

The allometric relationships of mean tree height H(=g_θ · w~θ) and of organ mass density d(=w/s · H = g_δ · w~δ,where d(=1/p)∝ w~Φ to mean organ mass w were studied in Bruguiera gymnorrhiza stands. According to Weller's allometric model, the self-thinning exponent a was estimated to be 1.11 in leaf, 1.55 in wood and 1.47 in aboveground. The self-thinning exponent a in leaf was not significantly different from 1.0, which showed that the stand leaf biomass was constant regardless of the population density p. The a was not significantly different from 3/2 in wood and aboveground, which concluded that the 3/2 power law of self-thinning holds in overcrowded B. gymnorrhiza stands.
