摘　　要：为了深入了解草坪节肢动物群落多样性的影响因子,对黄山学院校园内的草坪节肢动物总群落、非天敌和天敌亚群落的多样性与其他主要生态学指标之间的关系进行了通径分析。结果表明,总群落中多样性指数H′同各主要生态学指标均呈正相关,其中在总群落、非天敌和天敌亚群落中Simpson指数D、Pielou均匀度指数J和McIntosh指数DMC对多样性指数H′起决定性作用。由此可见,草坪节肢动物群落多样性水平的提高可通过生境增加节肢动物群落的Simpson指数D、Pielou均匀度指数J及McIntosh指数DMC来实现。Thorough investigate the effect factors of arthropod community diversity in turf, the relations between diversity index and its main ecological indices of total conanunities and sub- communities in Huangshan College yard were analyzed by path analysis. The results indicated that the diversity index had a positive correlation with its main ecological indices. The Simpson＇s index D, Pielou evenness index J and MeIntosh index of DMC played a decisive role in the general connnunity, non- natural enemies and natural enemy sub- communities on the diversity index H′. Thus, increasing arthropod community Simpson＇ s index D,Pielou evenness index Jand McIntosh＇ s index DMC lawn could raise the level of arthropod community diversity.
