城市不同绿地类型节肢动物群落的组成与结构
Community Structure and Composition of Arthropod among Different Urban Vegetation Types

为研究城市不同绿地类型节肢动物群落的组成和结构,调查了上海市常绿阔叶林、落叶阔叶林、混交林和落叶针叶林等4种不同绿地类型的16个样地中节肢动物的群落,共采集到节肢动物3纲11目40科,其中摇蚊科数量最多。不同绿地类型节肢动物群落多样性指数排序为:常绿阔叶林(2.09)>落叶阔叶林(1.83)>混交林(1.78)>落叶针叶林(1.76)。害虫亚群落的多样性普遍低于天敌亚群落,说明节肢动物群落中害虫所占的比例较低。因此,建议在城市绿地有害生物防控的过程中,注意对天敌和中性昆虫的保护。
In order to analyze the community structure and composition of arthropod in different urban vegetation types,16 plots belonging to four different vegetation types in Shanghai were sampled.The results showed that the arthropod specimens collected could be divided into 40 families belonging to 11 orders within 3 classes.Among them,the number of Chironomidae individual was the largest.The Shannon-Wiener index sequence of arthropod communities was:evergreen broad-leaved forest (2.09) > deciduous broad-leaved forest (1.83) > mixed forest (1.78) > deciduous coniferous forest (1.76).The diversity of pest sub-community was generally lower than that of natural enemy sub-community.Therefore,we should pay more attention to the protection of natural enemies and neutral insects in pest management.
