对云南轿子雪山自然保护区地表甲虫物的种组成及生物多样性季节变化进行了连续跟踪调查.调查结果如下:(1)通过对4种典型微环境样地(草地、灌丛、林地以及农田生态系统)连续3次跟踪连续调查,共获得标本2451头,分别隶属于24科.其中步甲科(Carabidae)为优势类群,占总数的62.10%;隐翅虫科(Staphylinidae)其次,占12.77%.可能由于海拔、气温等因素影响,该地区昆虫活动高峰期较短.(2)通过对4种典型微生态环境中地表甲虫的生物多样性的比较,表明不同生境内甲虫的多样性指数存在动态变化,在不同生境片区内甲虫存在迁移活动,甲虫多在灌丛中越冬,并随季节及食物源迁移.

Jiaozi Mountain, the nearest nature reserve away from Kunming, is one of the famous low-latitude-jokuls where the environmental balance affects the whole Kunming area. However, data about biodiversity in Jiaozi Nature Reserve were still unknown. In this paper, the composition and seasonal diversity variation of ground-dwelling beetle communities in Jiaozi Natural Reserve were estimated. The results showed that:(1) through the three-month study in 4 typical microhabitats ( grassland, shrub, coniferous forest and farmland) , 2451 beetles which were collected and analyzed belonged to 24 fami-lies. The carabids (family Carabidae) were the dominant group, which accounted for 62.10% of total individual number; the second common group was Staphylinidae (12.77% in total). It was indicated that the beetles'activeness period last short due to the high altitude and low temperature; (2) by com-paring the biodiversity indices of 4 microhabitats, it was found that there were migrating activities a-mong different sites. It was indicated that beetles over-wintered in shrubs and migrated with the season variation. The beetles' migrating activities probably accorded with the food source.
