摘要
本文对溪头林场毛竹纯林和毛竹混交林两种不同类型的毛竹林群落特征进行了研究 ,研究结果表明 :(1)毛竹混交林乔木树种主要是以石栎、木荷、杉木和松树为主 ,伴生有其他阔叶树种。(2 )毛竹混交林和毛竹纯林林下优势种植被具有明显的差异 ,这种不同的植被类型是植物在长期进化过程中对自然生态条件的一种适应性。 (3)毛竹混交林物种多样性指数、物种丰富度和群落均匀度均稍低于毛竹纯林 。
This paper mainly deals with the community characteristics of pure bamboo stand and mixed bamboo stand in Xitou forest station.The results show: (1)in mixed bamboo stand Lithocarpus glaber,Schima superba,Cunninghamia lanceolata,Pinus massoniana are dominam and accompanied by other broad leaved trees;(2)a great difference exists in dominant underplants between two types of bamboo stand,such a difference is a adapatability of vegetation to natural ecological environment during long evolution;(3)the tree species diversity,abundance the community evenness of the pure bamboo stand are some higher than those of the mixed bamboo stand respectively and it shows that the pure bamboo stand is a relatively stable community in nowadays stage.
