摘  要:
采取随机取样法对陕西淳化县人工林群落进行了研究,分析了不同人工林群落的物种组成、特征和物种多样性。结果表明,淳化县4种人工林群落共发现植物31种,分别隶属于15科24属,人工林群落的外貌特征主要由地面芽植物决定;α多样性中Shannon-Wie-ner、均匀度指数和丰富度指数的大小顺序依次为油松-刺槐混交群落>侧柏群落>刺槐群落>油松群落,而Simpson指数大小顺序与之相反;油松群落、刺槐群落和油松-刺槐混交群落之间的β多样性指数较高,而三者与侧柏群落的β多样性指数较低。

摘  要:
Artificial forest community in Chunhua County of Shaanxi Province was studied by adopting accidental sampling.Species composition,characteristics and species diversity of different artificial forest community were analyzed.Results showed that there were 31 kinds of plants in 4 types of artificial forest community,which belonged to 15 families and 24 genera.The appearance of the artificial forest community was mainly decided by hemicryptophytes.The descending order of α diversity indices including Shannon-Wiener index,evenness index and richness index was Chinese pine-locust tree mixed community,oriental arbor-vitae community,locust tree community and Chinese pine community while the order of Simpon index was opposite.β diversity indices among Chinese pine community,locust tree community and Chinese pine-locust tree mixed community were higher while β diversity indices between oriental arbor-vitae community and other three communities were lower.
