北川3种箭竹属植物地上生物量结构和回归模型的研究

A Study of Above-ground Bimass structure and the Regression Models of Three species of Fargesia in Beichuan

  • 摘要: 为深入了解箭竹群落生态学过程,探索大熊猫栖息地承载量,研究了北川小寨子沟自然保护区3种箭竹属植物油竹子、华西箭竹和糙花箭竹地上生物量分配格局,并建立了各器官生物量与基径和竹高的拟合模型。结果表明:(1)3种箭竹地上各器官中,竹秆的生物量最大,其次为竹枝和竹叶;其中在竹秆生物量分配中油竹子 > 华西箭竹 > 糙花箭竹,在竹枝生物量分配中糙花箭竹 > 油竹子 > 华西箭竹,在叶片生物量分配中糙花箭竹 > 华西箭竹 > 油竹子。(2)3种箭竹各器官生物量与基径(BD)有较好的相关性,其中基径(BD)与油竹子、华西箭竹、糙花箭竹鲜秆质量(W1)的拟合模型分别为W1=1/7.761+(-29.385e-B)、W1=0.367B2.614、W1=1/4.804+(-11.414e-B),根据这些模型可以较准确地估算出这3种箭竹群落的生物量,进而估算出大熊猫栖息地的承载量。

     

    Abstract: In order to understand the community ecology process of Fargesia and explore the carring capacity of panda habitat,studies were made of on the biomass distribution pattern of above-ground organs of three kinds of Fargesia and the regression models of each biomass component were also based on BD and culm height. The results showed that:(1) among the above-ground organs, the culm biomass was much more than the branch and leaf biomass. In the culm biomass allocation, Fargesia angustissima > Fargesia nitida > Fargesia scabrida. In the branches biomass allocation,Fargesia scabrida > Fargesia angustissima > Fargesia nitida. In the leaf biomass, Fargesia scabrida > Fargesia nitida > Fargesia angustissima. (2) Various components were highly correlated with BD. The models of fresh culm weight(W1) based on BD of the three Fargesia species were W1=1/7.761 + (-29.385e-B)(Fargesia angustissima), W1=0.367B2.614(Fargesia nitida), W1=1/4.804 + (-11.414e-B)(Fargesia scabrida). According to these models the community biomass of those three Fargesia species could be accurately estimated,and thus the carrying capacity of panda habitat could also be estimated.
