摘要: 对广东省东莞清溪林场短萼仪花(Lysidice brevicalyx Wei)群落的群落结构及其多样性特点和土壤肥力状况进行了研究。共设置了8个400m2的样方,4个样方设置于连片分布的沟谷林中,其余4个样方设置在山坡上零散分布的大树周围。在调查样方中共记录了维管植物142种,隶属于68科103属。沟谷片生林样方的Shannon指数高于散生树丛群落,山坡散生树丛样方的物种丰富度和均匀度指数高于沟谷林群落,相似性指数为0.41。两类群落的短萼仪花种群均缺乏小苗和幼树,种群结构呈衰退型。现有短萼仪花群落的土壤肥力与邻近的灌草丛群落相近,但较东莞市荔枝园和人工林地稍高。

Abstract: The composition and species diversity of the communities of Lysidice brevicalyx in Qingxi Forest Farm of Dongguan City,Guangdong were investigated by plot method.Eight plots with an area of 400 m2 were set up in two types of habitats.Four plots were in a relic ravine woodland stand while the rest four plots were in some separate,small patched woods.A total of 142 vascular species were recorded in the plots,which belong to 68 families and 103 genera.The result showed that the floristic diversity index was higher in the relic ravine woodland than those in small patched woods.However,the species richness and evenness of the latter types of woods were higher than the former type.The similarity index of the two community types was 0.41.Both population structures of the two community types possess a degraded pattern with only a few seedlings and saplings.The soil fertility was similar to the surrounding shrubland and grassland,but they were higher than the soils of the neighboring Litchi orchard and plantations.

Key words: Lysidice brevicalyx, floristic composition, population, species diversity, Dongguan City
