摘　　要：采用典型样地法,对鲁中山地三个地点的23块样地侧柏人工林林下植物进行了野外调查,分析了林下植物的丰富度、多样性、均匀度、生物量和盖度;利用因子分析方法对侧柏林下植物多样性进行了综合评价。调查发现共有林下植物53种,隶属于35科48属,以双子叶植物为主,占86.8%;不同侧柏林的林下生物丰富度、多样性和均匀度存在较大差异,但三者之间具有显著相关性。所有林下植物的多样性指数与其生物量、盖度均没有显著相关性,而林下生物量和盖度间的关系具有显著相关性。三个试验地点侧柏人工林下植物多样性平均标准化分值大小顺序依次为燕子山林场、黑峪林场和原山林场。By the method of typical sample plot, we investigated 23 plantations of Platycladus orientalis in three sites of the central Shandong mountainous region, and analyzed the richness, diversity, evenness, biomass and coverage of understory plants.Then, the understory plant diversity was evaluated using the method of factor analysis. The results showed that there were 53 species of undergrowth plants, belonging to 35 families and 48 genera, in which dicotyledonous plants accounted for 86.8%. There are significant differences in the richness, diversity and evenness of understory plants among different plantations, but significant correlation was found between them. There was no significant correlation between the diversity index and their biomass or coverage.However, the relationship between the biomass and the coverage was significantly correlated. The average standardized value of understory plant diversity of plantations in the three sites was in the order of the Yanzishan forest farm the Heiyu forest farm the Yuanshan forest farm.
