Even at less than 10mm, this "small" ground beetle larva is a huge and powerfulpredator to the tiny springtail in its jaws. It has all the characteristics

这种"小"步行虫的幼虫虽然体长不足10毫米，可对于被它擒在颚中的微小的弹尾虫来说，却是雄伟有力的掠食者。

But the macro fauna in orchard was different from others which including Acarina, Collembola, Nematodes and Hymenoptera. The common fauna was also different in different types of soil.

但果园样地优势类群有蜱螨目、弹尾目、线虫类和膜翅目，各试验样地的常见种类也有所不同。

Through investigation, 26 kinds of soil animal were collected , which could be classified into 9 classes belonging to 4 phyla. The dominent group taxa of among them were Nematoda, Collembola and Acarina.

在土壤重金属污染8个样地中，共获取土壤动物26类，隶属于4门9纲，优势类群为弹尾类、螨类和线虫类，常见类群8类，稀有类群15类。

Results show that in the region, Nematoda was the predominant group, and Acarina, Collembola, Tardigrada and Harpacticoida were common groups. Soil faunae under different vegetations at the same location displayed certain similarity and difference as well.

研究表明，整个地区不同生境中土壤动物的优势类群为线虫；常见类群有瞒、弹尾目、线蚓、熊虫和猛水蚤目等；同一地点不同植被下，土壤动物类群之间存在着一定的相似性和差异。

In Zigui Country, the numbers of Nematoda, Acarina and Collembola individuals were not much affected by habitat and elevation, while in Wanxian Country, the numbers of Acarina and Collembola were by elevation. In Shennongjia region, distribution of Nematoda varied significantly with vegetation. Acarina and Collembola were widely distributed in various soil layers under different vegetation, whereas the number of Acarina in the litter layer varied significantly with habitat and elevation.

对线虫、螨类和弹尾目的数量差异分析表明，秭归地区三个类群受植被、海拔影响不大；万县地区海拔对蝉蜡、弹尾目影响较大；神农架地区线虫分布受植被影响较大，蜡类和弹尾目在不同植被和土层广布，而该地区枯枝落叶层中螨类数量随植被、海拔变化显著。

Result In subalpine coniferous forest in western Sichuan, the Nematoda, Acarina and Collembola were the dominant groups of soil animal community and Diplopoda, Harpacticoida, Rotatoria, Enchytraeidae and Diptera were the frequent groups.

结果］川西亚高山针叶林土壤动物群落以线虫纲、蜱螨目、弹尾目为优势类群，以倍足纲、猛水蚤目、轮虫纲、线蚓科、双翅目幼虫等为常见类群。

Results indicated that both the amount of bacteria, epiphyte and actionmyces sharply and the amounts of acarina, collembolan and nematode were increased by application of organic fertilizer and the combined application of inorganic fertilizer with organic fertilizer for a longtime. Soil animal collembolan and nematode were significantly related to soil organic material and available phosphorous and available nitrogen. Acarina was significantly related to soil organic phosphorous, available potassium and available nitrogen.

结果表明：长期单施有机肥及其配施无机化肥，能显著增加土壤细菌、真菌和放线菌的数量，明显提高土壤动物蜱螨类、弹尾类、线虫类的数量，土壤动物弹尾类、线虫类与土壤有机质、有效磷、碱解氮呈极显著正相关；蜱螨类与土壤有机磷、速效钾呈极显著正相关；与土壤碱解氮呈显著正相关。

The results of the analysis to complete 18S rDNA and partial 28S rDNA D 6-7 domain sequences of 30 collembolan species supported the monophyly of Poduromorpha and Symphypleona, Entomobryoidea is not a monophyly, familia Neelidae should be separated from Symphypleona. The situation about the superfamilia of Tomoceroidea and the familia Neelidae need further studies. The results of the further analysis to complete 18S rDNA and nearlly completely 28S sequences of 4 Protura, 6Collembola, 5 Diplura, 5 Insecta, 10 Crustacean, using 1 Myriapoda and 1 Chelicerata as outgroups indicated that Protura, Collembola and Diplura are monophy, respectively, Protura and Diplura have the nearest realationship, they make sister groups with Collembola and all of them assemble with Insecta to make a monophy cluster of Hexapod; The results support the monophy of Pancrusracea, Crustacean is not a monophy cluster and the realationships between them with Hexapod need further reseachers.

对我国的14科27属30种跳虫的18S rDNA全序列和28S rDNA部分序列(D6-D7)的基因信息数据进行分析，结果支持原目、愈腹目的单系性，长角目不形成单系群，支持短角科从愈腹目中分出，但鳞总科和短角目的分类地位有待于深入分析探讨；进一步比对4种原尾虫、6种跳虫、5种双尾虫、5种昆虫和10种甲壳动物的18S rDNA全序列和28S rDNA全序列，以1种多足动物和1种螯肢动物为外群，进行系统关系分析，结果显示：原尾纲、弹尾纲、双尾纲分别为单系群，原尾纲和双尾纲优先聚为一支，然后和弹尾纲构成姐妹群，以上三类又和昆虫聚为一支，支持六足动物的单系性，支持泛甲壳动物，但甲壳动物并未形成单系，其各类群和六足动物之间的亲缘关系尚须进一步确定。3。

The abundance of Sminthuridae in the XS11 plot was higher than that in the KMD plot during the first month after transplanting.

在大田生长前期XS11田间以圆跳虫为主的弹尾虫比KMD田间的高，中后期弹尾虫基本消失，主要原因估计为缺少腐殖质来源：A89BC论62文网www.abclunwen.com

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
