摘要
为研究城郊农田土壤动物生态群落特征,选取贵阳市乌当盆地三种不同干扰程度农田作为样地,针对其中的土壤动物群落开展调查。调查中共获得土壤动物4695个个体,隶属于4门9纲21目,其优势类群为弹尾目、蜱螨目,常见类群有鞘翅目、伪蝎目、蜘蛛目、膜翅目、猛水蚤目、综合目和啮目,稀有类群包括前气门亚目、直翅目、等翅目以及双尾目和寡毛纲等15个类群。土壤动物群落特征在水平结构上表现为:两块种植蔬菜的农田土壤动物个体密度接近,而被弃耕的农田,其土壤动物个体密度远远大于正处于耕作中的农田;在时间结构上则表现为:7月>3月>11月,明显地表现出季节差异性;在垂直结构上,土壤动物数量表现为从上到下垂直递减趋势,具有明显的地表聚集性特征。
In order to study the ecological community characteristics of farmland soil animals in suburb,the farmland soil animals in Wudang basin of Guiyang city were selected as the research object.A total of 4695 soil animals were collected,belonging to 4 phyla,9 classes and 21 orders.The dominant groups were Collembola and acari.The common groups were Coleoptera,pseudoscorpio,Araneae,Hymenoptera,cycloptera,synthagora and Rodentia.15 rare groups include preaspira,Orthoptera,Isoptera,Diptera and Oligochaeta,etc.The characteristics of soil animal community in horizontal structure are as follows:the individual density of soil animals in two vegetable fields is close,while the individual density of soil animals in abandoned farmland is much higher than that in cultivated farmland;the time structure is as follows:July>March>November,showing obvious seasonal differences;in terms of the vertical structure,the number of soil animals showed a vertical decreasing trend from top to bottom,with obvious surface aggregation characteristics.
