Abstract:In order to reveal the characteristics of community structure, diversity and seasonal dynamics of collembolans in different habitats (natural forest, shelter forest, botanical garden, grassland, residential area, wasteland, and vegetable field) from Urumqi, surveys were conducted by using international general sampling methods, in April, July, September and November in 2008. The main findings of this study are as follows: A total of 3728 soil collembolans were captured and classified into 4 orders,13 families, 27 genera, respectively, of which the dominant groups included Pseudeachorutes, Hypogastrura, Onychiurus and Isotoma, accounting for 47.00% of total, Podura, Entomobrya, Proisotoma, Tullbergia, Cyphoderus, Sinella, Bourletiella, Desoria, Isotomiella, Neanura, Folsomina, Folsomia, Cyphoderopsis and Anurophorus et al. 14 genera belonged to common groupsaccounting for 47.65%and the others 9 genera belonged to the rare groups and they accounted for 5.35% only. There were significant differences of composition individual as well as diversity of soil collembolan among the 7 different habitats in Urumqi (P<0.05), the quantity orders of individuals were natural forest > shelter forest > grassland > botanical garden > residential area > wasteland > vegetable land. The vertical distribution of the individual densities and group numbers were mainly in the layer of 0~5 cm in the soil profile and with the increasing depth of soil layers, the number of individuals and groups of soil collembolan gradually declined. There were a significant differences of seasonal variation in the composition and individuals of soil collembolan communities, and the sequences of seasonal dynamics of individual quantity of the soil collembolan were September > July > April > November. Shannon-Wiener diversity index (H) rankings of different habitats were botanical garden > shelter forest > natural forest > grassland > residential area > wasteland > vegetable land. Simpson dominance index (C) were vegetable land > residential area > wasteland > grassland > natural forest > botanical garden > shelter forest. The similarity of collembolan communities among the 7 habitats were relatively low, only a few habitats reached certain similar levels. The research indicates that the soil nature, different vegetation types are the main factors that are influencing the collembolan community structure and diversity in this area.
