【摘要】 本文对贵州省青岩镇２０年生珍稀植物—青岩油杉种群生物量进行测定和研究。按平均标准木法实测了树干、树枝、针叶和根的生物量，根据实测结果用相对生长规律建立了测定单株木及器官的回归模型，进而亦得出了测定整个种群生物量的回归模型，模型的计测精度符合要求，具有实用价值。研究结果表明：２０年生青岩测杉种群生物量为５２．５８ｔ／ｈａ，其中树干、树枝、针叶和根的生物量比为４∶１．３∶１∶２．１更多还原

【Abstract】 In this paper, the biomass of 20-year-old Keteleeria davidiana var. Chien-peii colony in Qingyan Town of Guizhou province has been investigated and analyzed. The biomases of the whole and their organs haue been measured by “average standard tree”, method, and according to the standing crop of the destructive individuals, several regressve models have been established. In order to estimate the biomass of the similar colony, the regressive models of the mesarel colony and the trunks, branches, leaves and roots have been proposes. The result showed that the biomass of 20-year-old K.davidiana var. Chien-peii[WT9.5BZ] population is 52.58 t/ha, organs which, the biomasses of the trunks, branches, leaves and roots are 4∶1 3∶1∶2 1 respectively.更多还原
