Abstract

Abstract: An investigation on meso-micro soil fauna community structure was carried out under 4 plant configurations of urban green lands in Wenjiang District of Chengdu City. A total of 20 600 individuals of meso-micro soil fauna were obtained in different green lands, belonging to 19 orders and 45 families. Nothotylenchidae and Rhabditoidea were the dominant groups under 4 plant configurations. The number of groups and individual density of meso-micro soil fauna under lawn were higher than under the other 3 plant configurations in spring, summer, and autumn, while from autumn to winter they were higher under tree-shrub-grass land than under the other 3 plant configurations. The individual density of meso-micro soil fauna showed significant differences (F=3.23,P<0.05) among different plant configurations, and the C and J indexes of meso-micro soil fauna showed highly significant differences (F=7.48,P<0.01 for C;F=6.13,P<0.01 for J). The rank of groups and individual quantities of meso-micro soil fauna was saprozoie > predators > phytophage > omnivorous. The ratio of Acarina number to Collembola number changed with time, and it fluctuated more in winter and spring.

Key words: urban green land, plant configurations, soil fauna, seasonal dynamics
