有关暖温带土壤动物的研究,目前国内外尚无专门报道。为了开展这方面的工作,于1993年4月~1994年1月,在北京小龙门森林定位站设立了5个采样点,按国际通用方法每月进行一次定性定量的调查和采集,共采集各类土壤动物标本35 294号,它们隶属于5门、16纲、54目、176科、252属、356种。其动物类群数量及组成为:大型土壤动物(腹足类、蛛形类、多足类、膜翅类等)822个,小型土壤动物(蜱螨类为主)3129个,湿生土壤动物(线虫最多)31 227个,原生动物(主要为肉足虫及鞭毛虫)年平均量为789 238个/克·干土。土壤动物的数量消长趋势具有明显季节性变化;区系特点较突出,其种类组成情况和我国其它地区及相邻国家比较,均存在明显差异。

Up to now , there have been no special reports regarding soil animals in warm2temperate zone at home and abroad. From April 1993 to January 1994 ,by means of commonly- used quantitative and qualitative method , we carried out monthly sample collections in five plots in the Xiaolongmen Forestry Research Stations , Beijing. A total of 35 294 specimens were collected , belonging to five phyla , six classes , 54 orders , 176 families , 252 genera and 356 species. Among them , 822 individuals were large size soil animals ( Gastropoda , Arachnida , Myriapoda , Hymenoptera etc. ) , 3129 were small size animals (mainly ticks and mites) , 31 227 were wet land living soil animals (mainly nematods) , and annual mean occurrence of individuals per gram of dry soil of Protozoan (mainly Amoebae and Flagellates) was 789 238. The tendency of population fluctuation of dry soil animals showed evident seasonal variations and comparatively obvious fauna characteristics. There are similarities and differences regarding species composition compared with other areas in China and neighbouring countries.
