摘　　要：通过对酢浆草草坪和高羊茅草坪春季昆虫群落的系统调查,运用群落的重要指标对这两种昆虫群落进行了分析研究,并基本搞清了两种草坪昆虫群落的基本结构。结果表明,酢浆草草坪春季昆虫群落由10目25种组成,其中螨类(麦圆蜘蛛)是该群落的优势种;高羊茅草坪春季昆虫群落由10目21种组成,其中螨类(酢浆草茹叶螨)是该群落的优势种。两种不同草坪的昆虫群落主要指标在月份间存在明显的不同,说明群落演化过程不同。两种群落有一定的相似性,相似系数为0.611。这些研究为两种不同种类的草坪害虫综合治理提供了理论依据。The insect communities of Oxalis rubra and Festuca Arundinacea lawn were investigated and analyzed systematically by employing the important community indexes,and their structures were clarified. The results showed that the spring insect community of Oxalis rubra lawn was composed of 25 species in 10 orders and the dominant species were Penthaleus major（ Duges）, at the same time the spring insect community of Festuca arundinacea lawn was composed of 21 species in 10 orders ,and the dominant species Tetranychina harti. Because of the different succession courses in two kinds of lawns their community indexes were different ,and the similarity coefficient of two insect communities was 0.61. The results of this study could provide the scientific basis for IPM of these lawns.
