为了查明不同海拔高度对土壤动物群落多样性及其时空动态的影响,对乌鲁木齐雅玛里克山6种不同海拔高度样带土壤动物群落进行了调查分析,以探讨雅玛里克山土壤动物群落结构与不同海拔高度之间的关系.结果表明,共获得大、中小型土壤动物7 375只,隶属于6门16纲35目,其中真螨目(52.28%)和弹尾目(15.61%)为优势类群,共占总捕获量的67.89%,而寄螨目(8.37%)、三肠目(7.78%)、膜翅目(2.74%)、茅线目(1.53%)、双翅目幼虫(1.48%)、垫刃目(1.27%)、鞘翅目(1.11%)及半翅目(1.07%)等8类为常见类群,占总捕获量的25.35%,其余的25类为稀有类群,占总捕获量的6.76%.在6种不同海拔样带土壤动物个体数和类群数之间存在显著差异(P<0.05),个体数顺序为:样带A>样带B>样带C>样带E>样带D>样带F,而类群数顺序为:样带A>样带B>样带C>样带D>样带E>样带F.3个不同季节有明显的差异(P<0.01),其个体数依次为秋>春>夏.在6种不同高度样带和不同生境土壤动物群落多样性指标之间存在差异(P<0.05).组间聚类和排序结果表明,将6种不同海拔高度生境分为山底生境型、山中生境型及山顶生境型等三大类型.
In order to find out the effects of altitudinal height on soil animal community diversity and its temporal and spatial dynamics, soil animal communities in six sample transects at Yamalik Mountain, Urumqi, were surveyed to investigate the soil fauna The results showed that a total of 7 375 large, small and medium sized soil fauna were found, belonging to 6 orders, 16 orders and 35 orders, of which Acarina (52.28%) and Pintail (15.61%) were found, Which accounted for 67.89% of the total catch of the dominant species, while the order of the mites (8.37%), Trichomonas (7.78%), Hymenoptera (2.74% (1.48%), Dictyophora (1.27%), Coleoptera (1.11%) and Hemiptera (1.07%) were the common groups, accounting for 25.35% of the total, while the remaining 25 were rare, Accounting for 6.76% of the total catches. There were significant differences (P <0.05) between the number of individuals and the number of taxa in soil samples of 6 different elevations. The order of individuals was: transect A> transect B> transect C> Sample zone E> Sample zone D> Sample zone F, while the order of the number of taxa was as follows: transect A> transect B> transect C> transect D> transect E> transect F.3 different seasons (P <0.01), and their individual numbers were autumn> spring> There was a significant difference in the diversity index of soil fauna among 6 different elevations and habitats (P <0.05) .The clustering and ordination results showed that 6 different habitats were divided into hillside habitat , Mountain habitat type and the top of the Habitat type three major types.
