摘要: 土壤动物参与自然界的物质循环和能量流动,是土壤肥力的生物学指标之一。研究城市绿地土壤动物群落特征对于客观、全面评价城市绿地生态功能具有重要意义。采用干湿漏斗法对温江区城市绿地4种植物配置下中小型土壤动物的群落特征进行研究。结果如下:4种植物配置共获得中小型土壤动物20 600只,分属19目45科;伪垫刃科和小杆总科为4种植物配置的优势类群;春夏秋3季中小型土壤动物的类群数和个体密度均以草坪高于其他3种植物配置方式,而秋末到整个冬季则以乔-灌-草最高;各种植物配置下,中小型土壤动物个体密度具显著差异(F=3.23,P<0.05),中小型土壤动物优势度指数C及均匀性指数J具极显著差异(F=7.48,P<0.01;F=6.13,P<0.01);各种植物配置下,中小型土壤动物各功能团的类群数和个体数均为腐食性 > 捕食性 > 植食性 > 杂食性,蜱螨目与弹尾目数量比随时间表现出不同的规律,冬、春季起伏较大,夏、秋季相对平稳。研究表明,城市绿地生态系统中,气候和植物配置是影响土壤动物群落结构的重要因素。在水热条件较差的冬季,复杂的植物配置提供了更丰富的食物和更多样的生境,往往具有更高的土壤动物多样性。

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.
