摘要
于2005年3-5月份在衡山不同海拔高度设样地采集昆虫标本并进行相关分析。结果表明：昆虫种类和数量随时间和海拔高度的变化而有较大差别,在本次调查中双翅目、膜翅目、鞘翅目在衡山是比较稳定的优势种群;优势度指数因海拔高度、采集标本时间不同而有差异;不同采集时间不同海拔高度的多样性指数相差不大;中海拔地区的均匀度指数在每个采集时间里都较高、低海拔地区的稍高。
Insect specimens were collected from March to May 2005 at different altitude levels in Mount Heng, and the correlation of data was analyzed. The results showed that insect species and number were greatly different at different altitude levels and time, and Diptera, Hymenoptera and Coleoptera were more stable dominant populations in all researched ones; insect dominance indexes were different at different altitude levels and time, but insect diversity indexes were close; evenness indexes were slightly higher at middle altitude areas than ones at low and high altitude areas.
