毛竹林;林下植物;物种多样性;分布格局
摘  要：
调查了不同结构毛竹林林下植被物种多样性及分布格局状况,结果表明,毛竹纯林和竹阔混交林下植被物种有30~42种,竹阔混交林下植物种类比毛竹纯林多8~13种,竹阔混交林下植被的辛普森指数高于毛竹纯林,而香农—威尔指数竹阔混交林与毛竹纯林接近,种间相遇机率、生态优势度和均匀度除个别指标值差异较小,毛竹混交林与毛竹纯林多样性指数值相差不大。毛竹纯林与竹阔混交林下植被优势物种并不明显,物种的分布格局也趋于一致。

摘  要：
Investigation was carried out on underplanst species diversity and distribution patterns of different structured Phyllostachys heterocycla var. pubescens stands. The results showed that there had about 30 ~ 42 species underplants in pure bamboo stands and mixed one with broadleaved trees, but in mixed stands there were 8 ~ 10 underplants species more than pure bamboo stands. And Simpson diversity index of mixed stands was higher than that of pure ones. However, Shannon-Wiener diversity index was similar. Diversity index had no evident difference between pure and mixed stands except few index. There was no evident dominant underplant species in pure or mixed stands, and had similar distribution pattern in various stands.
