摘 要:对高羊茅草坪昆虫群落作系统调查,并运用群落的重要指标:总量(S)、丰富度(N)、多样性指数(H′)与均匀度(J)对其进行分析。结果表明,高羊茅草坪昆虫群落由12目43种组成,其中螨类、夜蛾与蚜虫是高羊茅草坪昆虫群落的优势种。高羊茅草坪昆虫群落9月份丰富度33,4月样本昆虫数达到1075只。5-10月该群落的多样性指数都较稳定,均匀度也较稳定。其演替过程可分为建群、发展、鼎盛与衰退共4个阶段。其中,鼎盛阶段是高羊茅草坪害虫群落治理的关键时期,因此做好调查意义重大。对此现象的原因进行分析为高羊茅草坪害虫综合治理提供了理论依据。The structure and succession of the insect community in Festuca arundinacea lawn were investigated systemically using the four important ecological indexes (N, S, H'and J). The results showed that this community was consisted of 43 species in 12 orders, and the dominance species were mites, noctuid and aphides. The value of N was 33 in September, and the value of S reached 1075 in April. Furthermore, the values of H' and J in this community were steady relatively from May to October. The succession of this community could be divided into four periods (Sysngenesis Phase, Development phase, Climax and Decline phase), and climax phase was the key period for integrated management, so the investigation of this phase was most important. These analysis results could provide scientific basis for IPM of this lawn.
