云南火烧梁子自然保护区土壤甲螨多样性及区系初步研究

Diversity and Preliminary Study on the Fauna of Soil Oribatid Mite in Huoshaoliangzi Nature Reserve in Yunnan Province

通过对火烧梁子自然保护区中土壤甲螨进行多样性和区系初步研究,结果表明保护区内甲螨种类多,共计25科,28属.其中疹丘甲螨属(Papillacarus)、珠甲螨属(Damaeus)、沙甲螨属(Eremulus)、窝甲螨属(Fosseremus)、尖棱甲螨属(Ceratozetes)为该保护区的优势属.多样性分析表明,保护区优势度物种小,复杂程度高,各物种个体数目不均匀.该保护区的甲螨在中国各个动物地理区都有分布,主要分布在东洋界以及古北界的东北和华北区,共有11类区系型.

The diversity and the fauna of soil oribatid mite in Huoshaoliangzi nature reserve in Yun- nan province were studied. The results showed that the reserve of oribatid mite species belonging to 25 families, 28 genera. The genus of Papillacarus,Darnaeus, Erernulus,Fosseremus,Ceratozetes are the dominant genera. Diversity analysis showed that,reserve dominance species of small,com- plex degree increased,and the number of individuals of each species is not uniform distribution. The reserve of oribatid mites are distributed in various animal geographical regions,mainly dis- tributed in the Palaearctic Oriental region,the northeast and North China region. Moreover,there are 11 types of flora types.
