摘要: 通过原始雨林与砂仁种植群落的比较,分析了在西双版纳地区沟谷雨林林下种植砂仁对沟谷雨林群落种类组成、结构、外貌和动态,以及幼树个体生长的影响.沟谷雨林林下种植砂仁对雨林的生物多样性有较大的破坏,造成种植群落70~90%的物种流失,约98%个体消失.其中草本和灌木植物种类和个体基本全部消失,乔木植物种类损失60~70%,个体损失50~80%.种植砂仁使群落垂直结构变得简单,分层明显.种植后的群落仍保持雨林的外貌,但已不再是雨林群落,变成稳定性较差的次生林群落.

Abstract: By comparing the community characteristics between primeval rain forest and planted A momum, the influence of A momum planted in ravine rain forest on the species composition, structure, physiognomy and dynamics of the forest, and its juvenile growth were studied.Planting A momum in the rain forest destroyed the biodiversity of the forest, and made 70~90% of its species and above 98% of its individuals disappeared. All shrubs and herbs almost disappeared, and 60~70% of tree species and 50~80% of their individuals were lost. Planting A momum made the community structure simple and the layers obvious. The community after A momum planting keeps the physiognomy of the rain forest, but is an unstable secondary forest, and not a rain forest.
