Study on community structure and compostion of arthropod in urban greenbelt | 城市绿地节肢动物群落组成及结构研究

chinois. 为提高园林害虫综合治理能力，保持园林生态系统的持续稳定，本研究在保定市选取了4种类型城市绿地，并对其节肢动物群落组成及结构进行了研究。结果表明：保定市园林植物节肢动物群落较为丰富，共收集到节肢动物14目70科185种56781头；优势类群依次为：同翅目、蜱螨目、半翅目、鞘翅目、膜翅目、鳞翅目、双翅目，其中同翅目数量最多，其次为蜱螨目。害虫亚群落分属于8目38科108种，主要害虫类群是蚜虫、叶蝉、叶螨等。天敌亚群落分属于9目18科28种，主要天敌类群有草蛉、瓢虫、姬蜂等。天敌亚群落中的物种分布较均匀，而害虫亚群落物种分布相对不均匀。植物配置丰富、人为干扰较少的植物园节肢动物群落稳定性相对较强，人为活动频繁的竞秀公园和濒临交通主干道的滨河公园节肢动物群落稳定性相对较差。[著者文摘]

anglais. Community structure and composition of arthropod in four different urban green spaces were analyzed to improve the abilities of integrated control of pests and maintain the stabilization of garden ecosystem. The results show that 56781 individuals belong to 14 orders among the collection of 70 families and 185 species. It indicated that the dominant orders were Homoptera, Acarina, Hemiptera, Coleoptera, Hymenoptera, Lepidoptera, Diptera. The individual amount of Homoptera is the largest and next is Acarina. The pest sub - communities belong to 8 orders 38 families and 108 species, and main pests are aphid, leafhopper and acarus. The natural enemy sub-communities be- long to 9 orders 18 families and 28 species, and main natural enemies are Chrysopidae, Coccinellidae and Ichneumonoidae. The species are distributed more equably in the natural enemy sub - communi- ties than in the pest sub - communities. The stability of arthropod community is worse in Jingxiu Park and Shore Park than in Arboretum, because human activities are more frequent in Jingxiu Park and Shore Park is closer to main traffic routes.
