对云南省永仁县白马河林场云南箭竹(Fargesia yunnanensis)秆、枝和叶片含水量及生物量进行了调查.结果表明:云南箭竹叶片的含水率最高,秆的最低;在地上部分各器官的生物量分配中,秆所占比例最大,可达60.31%～65.34%,枝次之(19.28%～21.87%),叶(15.11%～17.82%)所占比例最少.通过回归分析探讨了云南箭竹各变量的相关性,并对其各器官的生物量及秆高与胸径和地径进行模型拟合.其中秆、枝和叶的生物量与胸径的拟合方程分别是:(W_C=)0.318D~(1.753),W_B=0.135D~(1.412),W_L=0.140D~(1.216).应用上述相关数学模型估算不同地理种源云南箭竹各器官生物量.通过对胸径、地径和生物量的比较,认为鸡足山的云南箭竹长势最好.

The biomass and humidity contents of Fargesia yunnanensis in Baimahe forest farm, Yongren county, Yunnan province were investigated. The results showed that: the humidity content was the highest in the leaf, while it was the least in the culm. The biomass of culm ranks the highest, which is about 60.31 %-65.34 %, followed by the branch ranging from 19.28 % to 21.87 % and leaf is the lowest varing from 15.11 % to 17.82 %. The correlations among various organs were probed by regression analysis. The mathematical models among the biomass of various organs the diameter on breast height (DBH) and the diameter of bottom culms (DBC) were fitted. The biomass fitting models of various organs with DBH are (W_C=)0.318D~(1.753), W_B=0.135D~(1.412), W_L=0.140D~(1.216) respectively. According to the survey of DBH and DBC, the different organ biomass of F.yunnanensis distributed in different provenance were evaluated using the mathematical models. It showed that the growth vigour of F.yunnanensis distributed in Jizushan is the best by the comparision of DBH, DBC and biomass.
