为了解准噶尔盆地东南缘绿洲-荒漠交错带土壤跳虫群落结构特征及其变化,在2011年4、7、9和11月中旬对该交错带胡杨林、防护林、荒草原、灌木林、荒漠、菜瓜地及耕地等7种典型生境土壤跳虫群落特征进行比较研究。结果表明,共获得土壤跳虫2487只,隶属于4目10科17属。其中球角跳属Hypogastrura、伪亚跳属Pseudeachorutes、棘跳属Onychiurus、等节跳属Isotoma为优势类群,占总数的64.58%。长跳属、驼跳属、原等跳属等10个属为常见类群,占总数的33.26%。小圆跳属、短角跳属、疣跳属为稀有类群,占总数的2.16%。绿洲-荒漠交错带不同生境土壤跳虫群落组成、个体数以及不同季节间存在显著差异(P<0.05),其中个体数依次为胡杨林>防护林>灌木林>耕地>荒草原>菜瓜地>荒漠。不同季节土壤跳虫个体数顺序为夏季>春季>秋季>冬季。研究表明不同生境土壤湿度、植被类型及人为干扰程度是影响该交错带跳虫群落结构的主要因素。
In order to understand the characteristics and changes of soil demoderm community structure in the oasis-desert ecotone in the southeastern margin of Junggar Basin, Soil and cultivated land of seven typical habitats of soil spring insect community characteristics were compared. The results showed that a total of 2487 soil insect hoppers were obtained, belonging to 4 orders, 10 families and 17 genera. Hypogastrura, Pseudeachorutes, Onychiurus and Isotoma belonged to Isotoma, accounting for 64.58% of the total. Long jump, camel hopper, the first hop and other 10 genera are common groups, accounting for 33.26% of the total. Small round hop, short-angle hopper, wart hop is a rare group, accounting for 2.16% of the total. There was a significant difference (P <0.05) in the community composition, number of individuals and different seasons in the community of oasis - desert ecotone in different habitats. The individuals were Populus euphratica forest> shelter forest> shrub land> arable land> wasteland> rape field> desert. The order of individual numbers of soil spring insects in different seasons was summer> spring> autumn> winter. Studies have shown that soil moisture, vegetation types and human disturbance in different habitats are the main factors affecting the community structure of the staggered belt.
