| 摘 要：2001年10-11月，通过手检和Tullgren法分离方法对鼎湖山保护区7种不同森林群落的土壤动物进行初步调查，共获得土壤动物32类38017只，隶属4门、14纲、25目1科，其中大型土壤动物19类，其中优势类群3类：直翅目（Orthoptera）、综合纲（Pauropoda）、颤蚓目（Tubificida），常见类群8类：后孔寡毛目（Opistopora）、蜱螨目（Acarina）、等足目（Isopoda）、倍足纲（Diplopoda）、地蜈蚣目（Geophilomorpha）、双尾目（Diplura）、蜚蠊目（Blattoptera）、等翅目（Isoptera）、鳞翅目（Lepidoptera），两者占总个体数的98.20%；中小型土壤动物11类，其中优势种2类：蜱螨目（Acarina）、弹尾目（Collembola），常见类群1类：膜翅目（Hymenoptera），两者共占总个体数的98.40%。此外还发现土壤动物的幼虫2类，以及其他土壤动物的幼虫共计1316只，占土壤动物总数的3.50%，其中数量最多的是鳞翅目、同翅目，占总数的73.63%，分析表明：大型土壤动物针阔混交林最多，其次依次是河岸常绿阔叶林、南亚热带典型常绿阔叶林、针叶林（马尾松林）、常绿阔叶林、沟谷常绿阔叶林、灌丛草丛；类群数河岸常绿阔叶林最多，其次依次是南亚热带典型常绿阔叶林、针阔混交林和常绿阔叶林、针叶林（马尾松林）、沟谷常绿阔叶林和灌丛草丛。中小型土壤动物个体数针阔混交林最多，其次依次是针叶林（马尾松林）、河岸常绿阔叶林、南亚热带典型常绿阔叶林 、沟谷常绿阔叶林 、常绿阔叶林、灌丛草丛；类群数为南亚热带典型常绿阔叶林最多，其次依次是针阔混交林和针叶林（马尾松林）、沟谷常绿阔叶林和灌丛草丛和常绿阔叶林 、河岸常绿阔叶林；类群数南亚热带常绿阔叶林、针阔混交林、针叶林（马尾松林）最多，其次是沟谷常绿阔叶林和灌丛草丛和常绿阔叶林，河岸常绿阔叶林最少。土壤动物的类群数和个体数有随着土层深度的加深而递减的趋势。 |

| 摘 要(英文)：From Oct. to Nov. 2001， samples from 7 types of forest community in Dinghushan， were collected for soil faunas analysis by hand check separation and Tullgren method. 32 kinds of soil fauna had been collected and identified， belonged to 4 Phyla， 14 Classes 25 Orders and 1 Family. They were grouped by size into large， middle and small fauna. The middle and small group included 11 kinds， 2 dominant species(Acarina、Collembola) and 1 common species(Hymenoptera)， and 19 kinds， 3 dominant species(Tubificida、Pauropoda、Orthoptera) and 8 common species(Opistopora、Isopoda、Diplopoda、Geophilomorpha、Diplura、Blattoptera、Isoptera、Lepidoptera) were included in the large group. In addition， 2 kinds of soil larva were also found. The result indicated that the distribution in number of the large soil fauna was dominated in the mixed pine and broad-leaved forest， and then followed the order of river bank forest > monsoon evergreen broad-leaved forest > mass pine forest > mountain evergreen broad-leaved forest > ravine evergreen broad-leaved forest > shrub and grassland， while the groups were as the order of river-bank forest > monsoon evergreen broad-leaved forest > mixed forest > mountain evergreen broad-leaved forest > masson pine forest > ravine evergreen forest > shrub and grassland. The middle and small fauna in number was largely proportioned in the mixed pine and broad-leaved forest， and then followed the sequence of masoon pine forest > river bank forest > monsoon evergreen broad-leaved forest > ravine evergreen forest > mountain evergreen forest > shrub and grassland， while groups were largely presented in the monsoon evergreen forest， mixed forest， masson pine forest， and then ravine evergreen forest， shrub and grassland， mountain evergreen forest and river bank forest. The group number and individual number of soil fauna varied with soil depth， generally declined from the surface soil to the bottom layer within soil profiles. |
