对长白山红松阔叶混交林分布的上缘、典型分布区和分布下缘土壤动物群落进行研究。结果表明,红松阔叶混交林三个分布区土壤动物群落组成存在差异,其中典型分布区土壤动物多样性指数较高,群落组成均匀。甲螨亚目、辐螨亚目、节跳虫科、球角跳虫科、革螨亚目和山跳虫科相关性较大,共同出现在各分布区。土壤动物垂直分布具有明显的表聚性,且红松阔叶混交林的上缘和典型分布区表聚性更为突出。通过灰色综合关联度分析表明,土壤全钾、全氮和有机质含量对土壤动物群落影响较大,而土壤全磷含量和pH对土壤动物的影响次之。
The upper edge, typical distribution area and distribution of soil fauna in the Pinus koraiensis broad-leaved mixed forest in Changbai Mountain were studied. The results showed that there were differences in the composition of soil animal community in the three distribution areas of Korean pine broad-leaved mixed forest, in which the diversity index of soil animal in the typical distribution area was higher and the community composition was even. A mite subfamily, spider mite subfamily, Arthropod section, the ball hornhoppers Division, leather mites Subfamily and Mountain Spring Division relatively large, common in the distribution. The vertical distribution of soil fauna showed obvious polycation, and the polygamy was more prominent on the upper edge and typical distribution area of the mixed forest. Through the gray comprehensive correlation analysis, it showed that total potassium, total nitrogen and organic matter content of soil had a great influence on soil animal community, followed by soil total phosphorus and pH on soil animals.
