摘　　要：采用大型手捡、Tullgren干漏斗和Baermann湿漏斗法对川芎种植基地土壤动物群落进行调查.结果显示,试验所采集土壤动物平均密度为3.13×104只/m2,其中,川芎样地土壤动物平均密度为1.35×104只/m2,11个类群;菜地土壤动物平均密度为4.91×104只/m2,15个类群.同功能种团分析表明,菜地的杂食性和腐食性土壤动物密度显著高于川芎地(P<0.05),植食性和捕食性显著低于川芎样地(P<0.05).菜地的DG和C指数高于川芎样地,而J和H'指数低于川芎样地.表明川芎种植对土壤动物群落分布与多样性特征产生一定影响.An investigation of soil fauna was carried out in Ligusticum chuanxiong Hort plantation. The average density of soil fauna was 3.13×104 ind/m2, belonging to 3 phyla, 8 classes, and 16 orders. The density of soil fauna and group numbers in Ligusticum chuanxiong Hort field was lower than that in vegetable filed. The densities of omnivorous and saprozoic soil fauna in vegetable filed were significantly higher than those in Ligusticum chuanxiong Hort field（P〈0.05）, but the densities of the predators and phytophaga were lower（P〈0.05）. The values of DG and C indexes in vegetable filed were higher than those in Ligusticum chuanxiong Hort field, but the values of J and H＇ were lower.
