摘要
对大围山油料植物白檀种类及其分布进行了调查与分析。结果表明,大围山地区从海拔230~1 607m之间均有白檀植物分布,包括白檀、湖南白檀和华白檀。3个种均适生于弱酸性土壤,但形态性状差异明显,不同白檀种群的分布与海拔显著相关,华白檀散生于海拔800m以下,白檀在海拔400~1 200m均有分布,1 200m以上零星分布;湖南白檀于海拔1 200m以下地区偶有分布,1 200m以上地区形成成片灌丛。3个种的群落中,白檀群落结构最稳定,生境多样性最大,华白檀群落稳定性最差,多样性最小。
Investigation and analysis on species and their distribution of Symplocospp.in Daweishan Mountain were conducted.The results showed that from the elevation of 230 mto the top of 1 607 m,there were three species belonging to genus of Symplocos,those were S.paniculata,S.tanakana and S.chinensis.All the three species adapted to acidic soil.However,their distributions was significantly correlated with altitude,and their ecological traits were significantly different.S.chinensis distributed below800 m.S.paniculatadistributed mostly at the altitude from 400 mto 1 200 m,and scattered above 1 200 m.S.tanakanaoccasionally distributed below 1 200 mand formed into shrubs in the area above 1 200 m.Comparison of the three Symplocos spp.community,S.paniculatahad the most stable community structure and the largest habitat diversity,S.chinensis＇ community stability is the worst one,and hold the minimum habitat diversity.
