摘要：主要针对台州地区不同管理水平的狗牙根草坪进行环境因子与草坪昆虫群落多样性之间相互关系的调查，本次调查共选取3类草坪，每类草坪4个样地，共计12个样地。选用多样性指数和典范对应分析（CCA）等研究方法，对昆虫群落与环境因子的相关性进行了分析讨论。共采集昆虫样本9目223种，22 058头：以双翅目、直翅目、半翅目、鞘翅目、鳞翅目的物种占优势。在粗放、中等、精细管理的草坪中分别发现53种、151种、158种昆虫，共有种37种。用CCA分析结果表明杂草种类、土壤质地类型和疏松层厚度与昆虫的分布密切相关。

Abstract： To understand the correlation between insect community structure and environmental factors of bermudagrass lawns at different management levels in Taizhou， 4 groups at 3 management levels， 12 sample bermudagrass lawns were selected to analyze and discuss the correlation between insect communities and environmental factors with diversity index and canonical correspondence analysis（CCA）. The 22 058 insect individuals in 223 species， 9 orders were collected in number， in which Diptera， Orthoptera， Hemiptera， Coleoptera and Lepidoptera were dominant. Each bermudagrass lawn varied in the number of insect species， 53， 151 and 158 species were found respectively on lawns in well management， moderate management and poor management， and there were 37 common species. The CCA showed that weed species， the types of soil texture， and thickness of soil loose layer were closely related to the distribution of insects.

20世紀以来，人们生活质量逐年提高、环境保护意识日益增强，城市草坪业快速发展[1]。然而，城市草坪的管理水平却参差不齐，病、虫害时有发生，危害面积逐年扩大[2]。许多城市草坪失去绿色，呈现斑秃，严重时出现大面积毁灭，破坏了城市草坪应有的生态功能和观赏效果[3]。昆虫作为城市草坪生态系统中的重要类群，其多样性和丰富度通常与草坪植物多样性密切相关[1，3-8]。因此，对草坪昆虫群落进行系统研究，有望探明城市草坪昆虫群落结构、各种昆虫在群落中的地位、昆虫的消长情况和天敌的抑制作用，为草坪的综合治理提供理论依据[9]。然而，针对台州地区草坪昆虫的研究尚未见报道。
