摘要
云南地处我国西南边陲,东经97°9′—106°12′,北纬21°09′—29°15′之间。北回归线横贯本省南部,基本上属于低纬度地带的内陆地区。地势、气候复杂,自然条件优越,蝴蝶种类繁多,区系复杂多样。多年来,在本研究室同志共同努力下,对云南及邻近地区,进行了野外考察采集,共获蝴蝶标本12,000余号,初步鉴定出432种,隶属于11科,188属。为今后进一步研究云南昆虫区系的全貌,现对云南蝶类区系及地理分布作一初步分析。
Through many years of hard work by all members of the department of entomology about 12,000 butterfly specimens were collected from Yunnan province and its neighbouring regions. Besides a few of them are waiting for identification (new spscies or new subspecies) , about 432 species belonging to 188 genera in 11 families have been preliminaryly determined.
This paper deals with the scope of the fauna and geographical distribution. of butterflies in Yunnan. It has three parts.
The first part have discussed preliminarily the problem of the butterfly fauna of Yunnan based on the materials in hands at present. in order to explain the character of the Yunnan butterfly fauna, we classified the data quantitatively according to statistic procedure. As a whole the results show that about 74.42% of them are Oriental species. These are the main or majority part, about 14.19% of the species we collected are transitional or over leap-regional species. Only 11.4 % of these species are Palearctic species, and analysed the belongingness as well as percentage of Yunnan butterflies in Zoo-geographical division into districts of China.
The second part have discussed the characteristics of the distribution of Yunnan butterflies ( 1, the character of vertical distribution. 2 , the transitional character of the distribution. 3 , the character of distributional difference on the different sloping direction.)
The last part have discussed the obvious differences of the fauna constitution of various areas, according to the occurrence and distribution of butterflies characteristics, together with the physical geography, landform, climate and vegetation of the place, and divide these into 3 different types of regions as the following:
Ⅰ , The lower mountainous north tropical rain forest and monsoon forest subregion (about under 1,500 M.)
Ⅱ, The middle mountainous subtropical evergreen broad-leaf, mixed forest and coniferous forest subregion (about range 1,500?,000 M.)
Ⅲ, The high mountainous temperate zone of coniferous forest subregion (about range 3,000-4,600 M.)
