摘　　要：在陕北枣林研究区域内,以土壤动物为研究对象,采取野外调查取样、定点动态观测与室内鉴定分类的研究方法,选取了延安万花山、延川县、清涧县、佳县枣林4个样点7个样地,于2007年3月、6月、9月、11月,对土壤动物功能类群进行了初步研究。陕北枣林土壤动物可划分为植食性、捕食性、腐食性、枯食性、菌食性土壤、杂食性土壤动物6个功能类群,基于土壤动物功能类群与枣林病虫害生态调控的内在关系,建构陕北枣林害虫生态调控体系,为深入探讨土壤动物与枣林害虫生态调控的关系提供基础资料和理论依据。In the area of jujube forest in Northern region of Shaanxi,a preliminary study on the soil fauna guilds was carried on.The soil fauna was taken as the objects and was based on the combining research methods of field investigation sampling,fixed point dynamic observation and laboratory identity classification,at 4 sample points and 7 plots in Yan＇ an Wanhua Mountain,Yanchuan County,Qingjian County,Jia County in March,June,September and November in 2007.The soil fauna guilds could be divided into six function class groups which were herbivorous,predatory,saprophagous,debris-feeder＇s,fungivorous form and omnivorous soil fauna.Based on the relation between soil fauna guilds and ecological regulation of pests,the ecological regulation and management system of jujube forest pests in Northern Shaanxi Province was constructed,which could provide basic data and theoretical basis for further study on the relationship between the fauna and ecological regulation of pests in jujube forest.
