お? The composition of groups,the structure and seasonal variation of soil fauna in Chongqing Airport grassland in 1995-1996 were investigated The relation between soil fauna and birds was preliminarily analyzed The results showed that Aacarina was the dominant group,and the common-seen groups were soil macrofauna and mesofauna,which were bird’s main prey Soil microfauna whose activity was weak,and it’s likely to live in soil and humus Soil macrofauna whose activity was strong,it’s likely to live on ground...

对重庆机场草地土壤动物群落的组成、结构和时空动态特征进行了比较研究,初步分析了土壤动物与机场鸟类在种类和数量上的动态关系。结果表明:土壤动物的优势类群为蜱螨目;常见类群多为大、中型土壤动物,是鸟类捕食的主要对象;活动性弱的小型土壤动物及幼虫主要分布在土壤和腐质层中,且群落的多样性和稳定性较高;活动性较强的大、中型土壤动物则多分布在地表并因环境变化作迁移运动,其群落的多样性和稳定性较差。土壤动物类群数、个体数量和群落多样性指标在秋、冬季高于春、夏季。这些特性为鸟类在机场活动及栖息提供了较好食物资源和捕食条件,土壤动物群落的变化对鸟类活动产生一定程度的影响。相应于土壤动物种类和数量的季节变化特点,鸟类在种类和数量上的季节变化在时间上则表现出滞后现象。

Through ecological investigation, the composition,quantity and seasonal variation of the soil and grassland fauna communities were examined in Hongqiao airport Grassland, Shanghai. The preliminary correlation between soil or grassland fauna and birds was (preliminarily analyzed) completed. The results indicated that there were twelve groups of soil fauna, Arthropoda,Mollusca,Annelida etc. Acarina and Collembola were the main groups which made up for 19.75% and 23.14% of the total amount of catches in one year....

Through ecological investigation, the composition,quantity and seasonal variation of the soil and grassland fauna communities were examined in Hongqiao airport Grassland, Shanghai. The preliminary correlation between soil or grassland fauna and birds was (preliminarily analyzed) completed. The results indicated that there were twelve groups of soil fauna, Arthropoda,Mollusca,Annelida etc. Acarina and Collembola were the main groups which made up for 19.75% and 23.14% of the total amount of catches in one year. Earthworm,Myriapoda,Isopoda,Hymenoptera and Coleoptera were common groups which made up for 48.96% of the total amount of catches in one year. There were fifteen groups of grassland fauna. Coleoptera,Orthoptera,Hemiptera,Homoptera, Hymenoptera,Diptera and Araneida were the dominant groups among them. They made up for 89.63% of the total amount of catches in one year. The quantity of groups and individuals of grassland fauna were as follows: July>September>May>April> December>March. The distribution of soil and grassland fauna was related to their circumstances. Relatively, there were more soil and grassland fauna in high grass area. There were 20 groups for birds to catch directly in the 22groups of grassland fauna, most of which were common groups in grassland. Therefore the main reasons for birds to stay in airport grassland were grassland circumstances and grassland fauna. Reducing grass in height, decreasing the quantity of the bearing plants and limiting the density of soil fauna were effective ways to decrease the number of birds around airport.

20 0 0年 4月至 2 0 0 1年 3月 ,对上海虹桥机场草地土壤动物和草丛动物群落的组成、数量和季节性变化特征进行了初步的研究。土壤动物有节肢动物门、软体动物门、环节动物门等 12个目或类。其中蜱螨目和弹尾目为常年土壤动物群落的优势类群 ,各占年总捕量的 19.75 %和 2 3.14 % ;蚯蚓、多足纲、等足目、膜翅目、鞘翅目为常见类群 ,5类全年占总捕量的 4 8.96 %。草丛动物有 15目或类。其中鞘翅目、直翅目、半翅目、同翅目、膜翅目、双翅目以及蜘蛛目为草丛动物群落的优势类群 ,占全年总捕量的89.6 3%。草丛动物类群数和个体数总体表现为 :7月 >9月 >5月 >4月 >12月 >3月。土壤动物和草丛动物的分布与生境密切相关。所捕的 2 2类草地动物中 ,可直接被鸟类捕食的有近 2 0类 ,主要为生活于草地常见类群中 ,因此 ,草地的生境以及草地动物的分布是吸引鸟类到机场栖息和摄食的主要原因。降低草高、减少结实的植物、控制土壤动物的密度是减少机场区鸟类数量的有效方法和途径。
