| 摘 要： | 目的]研究迁安条桑昆虫的群落结构.方法]通过系统调查研究,对条桑昆虫群落的优势集中性指数、Shannon-Wiener多样性指数、均匀度指数、物种丰富度指数进行分析.结果]该条桑昆虫群落中共有昆虫72种,其中包括亚群落昆虫37种,占总数的51.39%,非害虫亚群落(包括天敌和中性昆虫)35种,占总数的48.61%.条桑昆虫群落结构稳定性较好,均匀度较大且优势种不明显.边缘效应对条桑昆虫群落结构具有一定的影响.处于样地边缘的条桑昆虫群落的生物多样性指数较低,而处于样地中心区域的条桑昆虫群落的生物多样性指数较高.结论]该研究为条桑害虫的综合治理提供了一定的理论基础. |

| Abstract: | Objective] The aim was to study the community structure of insects in mulberry shoot in Qian an.Method] the dominant concentration index,Shannon-Wiener diversity index,evenness index and the species richness index of the insect community in mulberry shoot were analyzed through systematic investigation.Result] There were 72 kinds of insects in the insect community in mulberry shoot,including 37 kinds of insects in subcommunity,which accounted for 51.39% of the total,and 35 kinds of insects in the non-pest... |
