摘　　要：在老秃顶子自然保护区北坡海拔700～1320m地段,从低海拔到高海拔设置12块样地,并采用Jaccard指数,对不同蜱螨目(Acarina)土壤动物群落间物种共有度的海拔梯度变化进行了分析。结果表明,不同海拔蜱螨群落间物种的共有度,无论以哪一生活层的螨类来表达,基本都以与其最相邻的群落间为最高。中气门亚目(Mesostigmata)、甲螨亚目(Oribatida)、蜱螨目(Acarina)螨类的共有度,均随着海拔差的增加呈下降趋势,但并不与植被情况完全吻合,低海拔群落间甲螨亚目、蜱螨目共有度大于高海拔,而中气门亚目则相反。An experiment was conducted to study from 700 m to 1 320 m on the northern slope suh showed that, for the species of different the co-occurrence of soil Acrina communities of Laotudingzi Mountain in Liaoning Province life forms or for all the species as a whole, the in 12 plots at different altitudes hy means of Jaeeard index. Reco-occurrence of soil faunae between neighboring communities was the highest. The co-occurrence of soil Aerina at different layers or all of the soil Aearina communities （Mesostigmata, Oribatida, Acarina） decreased with increasing altitude difference. Co-occurrence values of Acrina and Oribatida communities at low altitude were higher than those at high altitude, while a contrary resuh was showed among Mesostigmata communities.
