【摘要】 记录了陕西省洋县地区所辖秦岭南坡大熊猫保护区内的蝶类 191种 ,并对其中 179种的垂直分布与区系进行了分析。其区系成分中东洋、古北种混杂 ,东洋种占一定优势 ,这与秦岭的地理位置相一致。秦岭对东洋种的阻隔作用大于对古北种的作用。中山地带 (80 0～ 2 60 0m)即暖温带落叶阔叶林和中山针阔叶混交林带环境状况良好 ,气候条件优越 ,受人为干扰少 ,因而物种丰富、多样性较大。研究地区具有很高的保护价值。更多还原

【Abstract】 The scope of the fauna and geographical vertical distribution of the butterflies of the south slope of Qinling Mountains are studied.The investigators try to illustrate the conservation value of the Giant Pandas’ habitat through the study which spans 8 years.191 species are recorded,3 of them are China’s new records,and 44 of them are new records of Shanxi Province.\;The result of a serious of analysises shows that the percentages of Oriental species,Palearctic species and widely distributive species are 40\^8%,20\^9% and 31\^9% respectively.The fauna of butterflies of the south slope has the character of intergradation which is correlated to the geographic location of the Qinling Mountains.\;The obstruction of Qinling to Oriental species is more obvious to Palearctic species.\;The area in question has great conservation value as following aspects: (1) The population of butterfly shows great species abundance; (2) The heterogeneity of habitat revealed by the presence of multi\|subspecies and multi\|morphological species provides animals a steady habitat; (3) The faunal character and vertical distribution of butterflies show great value of ecological study; (4) The mid\|mountain (800～2?600?m) that has better environmental condition and less human disturbance is a typical shelter for the wild animals.更多还原
