摘    要:群落间各生活型土壤动物科及所有土壤动物科的共有度,一定程度上反映了群落间的相关性及沿环境梯度的物种替代关系。应用梯度格局法在长白山北坡海拔550~2650m地段,每隔100m海拔高度设置一块样地,共计22块样地,并应用Jaccard指数,对各海拔不同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,不同海拔土壤动物群落间物种的共有度,无论以哪一生活层的土壤动物科来表达,基本都以与其最相邻的群落间为最高,群落间物种共有度峰值与谷点反映了群落类型随海拔具有间断性变化。线虫、甲螨、弹尾等各生活型土壤动物的共有度以及所有土壤动物科的共有度,均随着海拔差的增加呈下降趋势,但并非与植被情况完全吻合。

关 键 词:长白山  物种共有度  土壤动物群落  海拔梯度

Abstract:The co-occurrence of soil fauna communities at different altitudes may reflect at some extent the relationships a-mong communities, their coexistence, and the replacement of species along the altitude gradient. The continuous or disjunctive distribution of different species along altitude gradient not only reflected the environment variation at altitude gradient, but also the biological and ecological spatiality as well as the adaptability of species. The northern slope of Changbai Moutain has not only a high diversity in soil fauna types and species, but also a high variation of diversity pattern along the altitude gradient, which is a perfect transect for the research of biodiversity and gradient patterns. From 550m to 2 560m on the northern slope of Changbai Mountain, twenty-two plots were investigated with an interval of 100m in altitude. By using Jaccard index, the co-occurrence of soil fauna communities at different altitudes was analyzed. For the species of different life forms or for all the species as a whole, the co-occurrence of soil faunae between neighboring communities was the highest, except for that between different soil fauna types. The peak and valley values of the co-occurrence of soil fauna communities along altitude gradient were matched with their gradient patterns, and the co-occurrence of soil faunae at different layers or all of the soil fauna communities were decreased with increasing altitude difference.
Keywords:Changbai Mountain  Co-occurrence of species  Soil fauna community  Altitude gradient
