Relationship between soil and grassland fauna characters and the birds in Hongqiao airport grassland,Shanghai
上海虹桥机场土壤及草丛动物群落特征和鸟类关系研究

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.
