摘要
为了了解松嫩平原不同纬度耕作草甸土的环境差异及其对土壤动物群落组成的影响。2009年5、8、10月在松嫩平原黑龙江部选取5个代表性耕作草甸土进行土壤动物群落区系组成调查,共捕获大型土壤动物33类、2088只;中小型土壤动物获22类、8372只,隶属于4门、7纲、19目、33科。研究结果表明:5个样地的土壤动物个体数和类群数水平生态分布具有明显的差异,呼兰土壤动物个体数和类群数占有绝对优势,纬度最高的嫩江最少;耕作草甸土中的土壤动物垂直分布表聚性不明显,与森林土壤动物相比形成鲜明对比。分析显示:不同地区土壤动物密度-类群指数不同,大型土壤动物:呼兰>海伦>绥化>依安>嫩江;中小型土壤动物:呼兰>海伦>绥化>嫩江>依安。
In order to reveal the differences of ecological environment,and the effects on the fauna composition.Five representative regions were selected in cultivated meadow soil regions of different latitude in Sonnen Plain.A total of 2088 individuals and 33 groups of macro soil animals,a total of 8372 individuals and 22 groups mid-micro soil animals were captured in May,August and October in 2009,which belong to 4 phylum,7 classes,19 orders and 33 families.The results showed that:individuals and groups of the soil animals varied greatly in horizontal distribution of different regions.Individuals and groups of the soil animals were dominant in Hulan,and the least in Nenjiang.The vertical distribution showed that soil animals mainly did not live in the surface soil layer,compared with those lived in forest soil.The analysis showed that:the DG index of the soil animals varied in different regions.The DG index of macro-soil animals was Hulan>Hailun> Suihua>Yi ' an>Nenjiang,and that of mid-micro soil animals was Hulan>Hailun>Suihua>Nenjiang>Yi ' an.
