摘要:
 为了研究延安市新区北区生态绿化林大型土壤动物的功能类群及其生态特征，并用于指导新区生态环境的恢复与重建提供理论依据。2015年3月、4月对延安新区北区3个样地的土壤动物进行抽样调查,在不同土层通过手拣法获取大型土壤动物128只隶属于2门4纲10目。结果表明，膜翅目、鞘翅目、蜘蛛目为优势类群；柄眼目、半翅目、弹尾目、石蜈蚣目为常见类群。通过群落多样性指数分析显示，松树样地的多样性指数和丰富性指数指数均大于刺柏和金叶榆样地，而且其个体数和类群数都多于刺柏和金叶榆样地。今后，在城市生态林建设中应保护和利用大型土壤动物的多样性，促进其功能和作用的发挥。
Abstract:
 In order to study the functional category and ecological characteristics of the macro-soil-fauna in the ecological forest in Yanan New District,and to provide theoretical basis for the recovery and reconstruction in the new district,a preliminary investigation on the soil animal was carried out by sampling survey method from three sites in Northern district of Yanan on March and April 2015.The soil macro-faunas were taken by hand sorting in different soil layers,128 individuals belonging to 2 phyla 4 classes and 10 orders were collected.The results showed that the dominant groups were Rhymenoptera,Coleoptera,Aranea,and the common groups were Styommatophora,Collembola,Hemiptera,and Lithobiomorpha.The composition of groups,distribution of the number of individual and diversity index of soil fauna were analyzed.The results indicated that the diversity and richness index of Pinus tabulaeformis plot were more than those of Juniperus formosana plot and Ulmus pumila Jinye plot.In addition．The total number of individuals and groups of P.tabulaeformis plot were more than those of J.formosana Hayata plot and Ulmus pumila Jinye plot.How to protect and to use the diversity of macro soil faunas and promote its function in the construction of urban ecological forests in future were discussed.
