摘要
2007年5月(春季)、7月(夏季)、11月(秋季)和2008年1月(冬季),对广州市天河区3种土地利用类型(林地、人工绿地、农田)下6个不同生境的中小型土壤动物群落的结构特征和季节变化进行了调查研究.结果表明:研究区不同生境下中小型土壤动物的水平分布有所不同.调查期间,华南农业大学树木园捕获的中小型土壤动物个体数最多,达1286个,农用地中捕获的个体数较少,以凤凰街农用地中小型土壤动物的个体数和类群数最低;研究区各样地中小型土壤动物的个体数总量有明显的季节消长,由高到低依次为:秋季(1815)>春季(1623)>冬季(1365)>夏季(1276).聚类与排序结果也说明不同生境样地的中小型土壤动物的群落结构组成随季节不同而呈现出明显的变化规律,同一季节不同生境的中小型土壤动物群落的组成和结构差异与人为干扰程度、土壤环境因素等有关.
Investigations were made in May,June,and November 2007 and January 2008 to study the structural characteristics and their seasonal variations of soil meso-and micro-fauna communities in six habitats of three land use types （forest land,constructed grassland and farmland） in Tianhe District of Guangzhou City. The horizontal spatial distribution of soil fauna differed with habitat. During the investigation periods,the Botanical Garden of South China Agricultural University had the highest individual number （1286） of soil meso-and micro-fauna,while the farmland,especially in the Fenghuang Street area,had the lowest number of individuals and groups. The seasonal variation of the individual number was in order of autumn （1815）〉spring （1623）〉winter 〉（1365）summer （1276）. Hierarchical clustering and detrended correspondence analysis also showed that the community composition of soil meso-and micro-fauna in different habitats exhibited distinct seasonal variation. In the same seasons,the community structure and composition of soil meso-and micro-fauna in different habitats were correlated to the degrees of human interferences and the properties of soil environment.
