摘要
在 1999年至 2 0 0 0年期间 ,对重庆市蝶类进行的调查表明 ,已知蝶类有 4 0 4种 ,隶属于 12科 171属。重庆市蝶类区系组成以东洋界为主体 ,占种数的 6 2 .1% ;广布种次之 ,占 2 3.3% ;古北界种最少 ,占 14 .6 %。根据聚类分析并结合地形、气候和植被 ,可大致将重庆市蝶类地理区划分为
In a survey of butterflies in Chongqing carried out in 1990 to 2000, 404 species were recorded, belonging to 12 families and 171 genera. The predominant types appeared to be the Oriental species, accounting for 62.1% of the total, followed by the wide-spread species, accounting for 23.3% of the total. The Palaearctic species were the least in number, accounting for 14.6% of the total. Cluster analysis in combination with consideration of the landscape , climate and vegetation of their distribution, the butterflies are zoogeographically divided into three regions.
