为了解雅玛里克山大型土壤动物群落的多样性及其生态分布特征,于2011年9月至11月在雅玛里克山对柳树林、草地、榆树林、果园、白杨林、荒地等6种不同生境中的大型土壤动物群落多样性进行调查和分析,采用手拣法采集大型土壤动物,并对其群落组成和多样性特征进行了比较分析.结果表明,共采集大型土壤动物1 730只,隶属于3门6纲19目,其中优势类群为膜翅目(Hymenoptera)、鞘翅目(Coleoptera)和直翅目(Orthoptera),占总捕获量的39.08%,其余17个类群为常见类群,占总捕获量的60.92%.在不同生境中大型土壤动物的个体数和类群数都不同,个体数量依次为:草地>果园>柳树林>榆树林>白杨林>荒地.类群数依次为:果园>柳树林和白杨林>榆树林和草地>荒地.在不同生境中大型土壤动物群落多样性指标之间存在差异,多样性指数依次为:柳树林>果园>白杨林>榆树林>草地>荒地.均匀度指数依次为:柳树林>果园>白杨林>榆树林>草地>荒地.优势度指数依次为:荒地>草地>榆树林>白杨林>果园>柳树林.该山区地表植被和土壤含水量可能是导致这一变化的主要因素.
In order to understand the diversity and ecological distribution characteristics of the large soil fauna community in Mt. Yamalik, the stands of willow groves, grasslands, elm trees, orchards, poplar forests, barren land and so on The diversity of macro soil fauna in 6 different habitats was investigated and analyzed, and large scale soil fauna was collected by hand picking method, and its community composition and diversity were analyzed comparatively.The results showed that a total of 1 730 Only belonging to 3 classes, 6 classes and 19 orders. Among them, the dominant groups were Hymenoptera, Coleoptera and Orthoptera, accounting for 39.08% of the total catch, and the remaining 17 were common groups , Accounting for 60.92% of the total catch.The number of individuals and taxa of macrofauna were different in different habitats, and the individual numbers were as follows: grassland> orchard> willow forest> elm forest> poplar forest> Orchards, poplar trees, elm trees and grasslands, and wasteland.The diversity index of macro-soil fauna was different in different habitats, and the order of diversity was as follows: willow forest> orchard> poplar forest> elm forest> grassland> Badlands. Evenness index The order of dominant degree index is: wasteland> grassland> elm forest> poplar forest> orchard> willow forest.The surface vegetation and soil water content in this mountain area may be the result of The main factor of this change.
