| 摘 要： | 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%~1782%)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：WC=0.318D1.753，WB=0.135D1.412，WL=0.140D1.216。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。 |

| Abstract: | 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 model... |
