Abstract: The allometric equations of biomassdiameter at breast height (DBH) and stand biomass densityleaf area index (LAI) of Phyllostachys edulis forests are helpful for biomass estimation with great accuracy. Here, the two fitted allometric equations, together with geostatistical technique, were employed to estimate biomass of moso bamboo forest in Huangkeng Town, southern Wuyishan Mountain, Fujian Province. A total of 103 moso bamboo culms were cut in Huangkeng Town to fit the allometric relationship between aboveground biomass and DBH at individual level. Standlevel LAI was derived from fisheye camera, which was used to develop equation between stand biomass density and LAI. Then geostatistical technique was used to estimate biomass of moso bamboo forest of the whole town. Significant power function relationships were found between aboveground biomass and culm DBH (R2=0.585, P=0.002), and between stand biomass density and LAI (R2=0.525, P=0.002). Based on the two fitted allometric equations and geostatistical technique, the mean biomass density of moso bamboo forest in Huangkeng Town was estimated as 53.49 t·hm-2, and the total biomass of the whole town was 0.62 Tg.
