摘　　要：在九华山 4种生境中共获土壤跳虫 590 4个 ,分隶 1 0科 52属。等跳科有 1 4属 ,数量占各科总数 72 .0 9% ,其中以符跳属个体数占绝对优势。不同群落组成成分及各项指标差异显著。混交林土层中种、数最丰富 ,若以土层和 Aoo层总和计算 ,则有高海拔生境群落比低海拔多的趋势。灌丛草甸土壤跳虫群落的 H和 E值高而且季节变化不大。秋冬季节各群落种、数都有增加 ,而以山上两个群落 Aoo层增加更多 。We collected 5904 individuals of Soil Collembola in four habitats in Jiuhua Mountains,and found that they belonged to 10 families and 52 genera. There were 14 genera in Isotomidae, whose quantity accounted for 72.09% of the total collected collembola. Among them, the individual number of \%Folsomia\% took the absolute predominance. There were marked difference among composition of Soil Collembola community in different habitats. Species number and quantity were the richest in the soil layers of mixed forest. In the soil layer and litter layer, the species number and quantity of the community in the high elevation habitat were more than those in the low elevation.\% H\% and \%E\% of the soil collembola community in the soil of shrub meadon were high and there were little change among seasons. Species number and quantity of each community both increaseed in Autumn and Winter. In the Aoo layer,the two commnuities on the mountains increased much more. The soil collembola tended to congregate to the sarface horizon in all habitats.
