中文摘要：

为研究林地类型对中型土壤动物多样性的影响,以巩义市农业景观中的林地为研究对象,分别于2014 年4月和7 月对该区农业景观中的3 种林地类型,即栓皮栎（Quercus variabilis）林、泡桐（Paulownia fortunei）林和杨树（Populus spp.）林内中型土壤动物进行取样,分析不同季节和不同林地类型间中型土壤动物多样性（丰富度和香农多样性指数）的差异.结果表明：不同类型林地内中型土壤动物多样性差异不显著,但非度量多维标度法（non-metric multi-dimensional scaling,NMDS）分析显示,春、夏两季栓皮栎林土壤动物群落组成均与泡桐林和杨树林之间存在显著差异,而杨树林和泡桐林之间差异则不显著.春、夏两季土壤动物多样性之间存在显著差异（P〈0. 001）,不同林地类型土壤动物多样性之间差异不显著（P〉0. 05）.海拔因子和草本植被高度对土壤动物多样性的影响不显著,但草本植被盖度与土壤动物多样性呈显著负相关（P〈0. 05）.不同林地类型为不同土壤动物类群的行为活动提供相适宜的生境,因此加强不同林地类型的保护,对于研究区内土壤动物群落的发展以及农业景观中生物体的流动具有重要意义.

英文摘要：

In order to study effect of type of woodland ( Quercus variabilis, Populus spp. and Paulownia fortune) on spe?cies diversity of soil mesofauna in Gongyi, samples of soil mesoanimals were collected from the woodlands for analysis of variation of the soil mesofauna with the season and type of woodland in diversity. Results show that the woodlands different in type did not differ much in soil fauna diversity, analysis using the non?metric multi?dimensional scaling ( NMDS) meth?od reveals that Quercus variabilis varied sharply from Paulownia fortunei and Populus spp. In soil fauna community structure in spring and summer, while Paulownia fortune did not vary much from Populus spp.; and soil fauna diversity differed significantly between spring and summer ( P<0?001 ) , but not much between woodlands different in type ( P>0?05). It was also found that elevation and height of herbosa did not have much effect on soil fauna diversity, but coverage of herbosa was negatively related to soil fauna diversity ( P<0?05) . The existence of soil fauna accelerates decomposition of woodland litters, and then promotes energy flow and material circulation in the woodland. At the same time, different types of woodland provide different types of habitats suitable for different types of soil fauna communities to inhabit and prey in. It is, therefore, very important to strengthen the protection of different types of woodlands for the development of soil fauna therein and bio?material flow in farming landscapes.
