摘要
对罗顿豆冠层的节肢动物群落进行系统调查,结果共采集到节肢动物1 093个个体,其中,害虫个体数最多,占群落物种个体数的46.92%,天敌占群落物种个体数的32.87%,中性昆虫占群落物种个体数的20.21%,多样性指数总群落>天敌亚群落>害虫亚群落>中性昆虫亚群落,均匀度指数天敌亚群落>总群落>害虫亚群落>中性昆虫亚群落,群落多样性指数与均匀度指数较高,波动幅度较小,生态系统比较稳定。总群落、天敌和害虫亚群落的多样性指数与物种丰富度呈显著的正相关,与物种丰盛度和均匀度无显著相关,天敌群落物种丰盛度与害虫物种丰盛度呈显著的正相关。
A systematic investigation on the composition and structure of the arthropod communities in the Lotononis bainesii canopies in 2009 collected 1 093 individual insects.Among them,46.92% were pests,20.21% neutala insects,and 32.87% natural enemies.The Shannon-Wiener index of the community significantly and positively correlated to their species richness in the order of∶ arthropod community﹥natural enemy subcommunity﹥neutala insect subcommunity﹥pest subcommunity.The species abundance of the natural enemies subcommunities significantly and positively correlated to the pest subcommunities（P0.05）.
