小篷竹群落邻体干扰指数的研究

A Study on Adjacent Interference Index of Drepanostachyum luodianense (Yi et R.S.Wang) Keng f Area

运用邻体干扰指数模型,分析小蓬竹群落种内、种间竞争强度,确立小蓬竹群落的竞争干扰因子。结果表明,在小蓬竹群落中,对小蓬竹干扰指数最大是猴樟,其次是小蓬竹本身。在自然情况下的群落演替过程中,猴樟种群将占优势,最终小蓬竹将在小蓬竹群落彻底消失。

Using the adjacent interference model,the intraspecific and innerspecific competition intensities were studied and the competition interference factors were established.The results showed that in Drepanostachyum luodianense（Yi et R.S.Wang） Keng f species,the maximum index was Cinnamomum camphora（Linn） Presd and the next was Drepanostachyum luodianense（Yi et R.S.Wang） Keng f.And the Cinnamomum camphora（Linn） Presd species would have priority in the natural community succession process. Drepanostachyum luodianense （Yi et R.S. Wang） Keng f would disappear thoroughly in the Drepanostachyum luodianense （Yi et R.S.Wang） Keng f area.
