不同喀斯特生境条件下小蓬竹构件生物量研究

Study on Modular Biomass of Drepanostachyum luodianense(Yi et R.S.Wang) Keng f.in Various Karst Habitats

对分布于不同喀斯特生境条件下的小蓬竹构件生物量进行了调查统计。结果表明,生境条件不同的小蓬竹地上构件生物量差异显著;同一克隆种群不同龄级的小蓬竹地上构件生物量也具有明显差异;地下构件在植株着生在某一生境的初期倾向于着生定居能力,后倾向于拓展空间能力。

The modular biomass of Drepanostachyum luodianense （Yi et R. S. Wang） Keng f. in different karst habits was studied. The result showed that the modular biomass of Drepanostachyum luodianense （Yi et R. S. Wang） Keng f. in different habits had prominent difference. The modular biomass of Drepanostachyum luodianense （Yi et R. S. Wang） Keng f. with the same cloning group and different age also had prominent difference. The belowground modular are adapt to settle when periphytic in a habit liminary, then inclined to expand space ability.
