文章2007年4月至5月期间对乌鲁木齐鲤鱼山公园(山顶87°34′759″E,40°50′566″N,山中坡87°34′716″E,43°50′577″N,山下坡87°34′488″E,43°50′993″N)三个不同海拔高度的土壤动物进行取样调查。本次调查共获大、中、小型土壤动物共3171只,经初步分类鉴定隶属于4门、10纲、19目,调查表明不同生境下,土壤动物的群落组成也不同,在三个不同海拔高度的土壤动物个体数量顺序为:山下坡(1493)>山中破(941)>山顶(737)。类群数量顺序为:山中坡(20)>山顶(18)>山下坡(16)。调查发现真螨目为优势类群,弹尾目、综合目、正蚓目、膜翅目、鳞翅目、等足目、柄眼目、双翅目、地蜈蚣目、鞘翅目、革翅目等11类为常见类群,其余的为稀有类群。同时对其不同海拔高度土壤动物个体数、类群数、Shannon-Wiener多样性指数、Pielou均匀度指数及Simpson优势度指数等群落结构指标进行分析并讨论,在不同高度和不同生境土壤动物各类群之间存在差异,并垂直分布调查发现具有明显的表聚特征,即从地表向下,随着深度的增加土壤动物类群和个体数量逐渐减少。
The article from April 2007 to May 2007 on Urumqi carp mountain park (Peak 87 ° 34’759 “E, 40 ° 50’566” N, mountain slope 87 ° 34’716 “E, 43 ° 50’577” N, Downhill 87 ° 34’488 “E, 43 ° 50’993” N) Soil samples from three different altitudes were sampled. In this survey, a total of 3171 large, medium and small soil animals were identified. The preliminary identification was classified into 4 groups, 10 classes and 19 orders. According to the survey, the composition of soil fauna was also different under different habitats. The order of the number of individuals of soil fauna was: hillside (1493)> hillside (941)> hilltop (737). The order of the number of taxa is: Mid - slope (20)> Peak (18)> Downhill (16). The survey found that Acarus is the predominant species, Eupolyphaga, Synthetic, Eupatorium, Hymenoptera, Lepidoptera, Isopoda, Diptera, Centipede, Coleoptera, Classes are common groups and the rest are rare groups. At the same time, the community structure index of soil fauna, Shannon-Wiener diversity index, Pielou evenness index and Simpson dominance index at different altitudes were analyzed and discussed. In different height and different habitats, There are differences between the two groups. The vertical distribution survey shows that there are obvious characteristics of surface polygons, that is, from the surface to the bottom, the number of soil fauna and individuals gradually decreases with the increase of depth.
