金佛山自然保护区蝶类区系组成及变化

记录了金佛山自然保护区蝶类152种，隶属于10科82属。蝶类区系成分以东洋界为主体。对金佛山蝶类的历史和现状对比分析表明，蝶类区系成分已发生变化。虽仍以东洋界成分为主体，但东洋界种数所占比例有所下降，广布种所占比例上升。表明金佛山的生态环境朝着有利于广布种生存的方向发展。

COMPOSITION OF BUTIERFLIES AND ITS EVOLUTION IN THE JINFO MOUNTAIN NATURAL RESERVE AREA

This paper presents a record of 152 species of 10 families and 82 genera of butterfly in the Natural Reserve Area in the Jinfo Mountains.The record shows that oriental species constitute the main types of the butterfly fauna.A comparative analysis of the past and the present status of the butterflies in this area reveals that the composition of butterflies has undergone considerable changes.Although the oriental species remain the main types,their proportion has decreased while widely distributed species have increased.The natural environment in the Jinfo Mountains seems to be developing in the direction favorable to widely distributed species.
