北京松山国家级自然保护区蝴蝶种类多样性调查

Butterfly species diversity in Beijing Songshan National Nature Reserve.

北京松山国家级自然保护区于2015年调整了功能区范围,为了解蝴蝶多样性的动态变化,完善物种名录,研究采用样线网捕法,于2019年4—8月对松山保护区进行了蝴蝶资源调查。结果共记录5科61属82种蝶类,其中8种为保护区新纪录。结合以往资料,整理得到松山自然保护区132种蝴蝶,发现不同时期的蝶类组成具有较大差异,可能与气候变化有一定联系。区系分析结果表明,2003—2019年间记录的132种蝴蝶以广布种为主,有67种,占50.8%,其次为古北种,占47.7%,东洋种则占比很小,说明松山的蝶类区系具有广布种与古北种混杂的特征。本次调查为松山保护区变更功能区后提供了蝴蝶种类本底资料,有助于后期开展动态监测。

The protected areas were adjusted in Beijing Songshan National Nature Reserve in 2015,in order to complement the butterfly species checklist and understand the changes of butterfly diversity,a baseline survey was conducted by using the line transects and net trapping from April to August of 2019.A total of 82 butterfly species in 61 genera and 5 families were identified,among which 8 species were new records to the reserve.Combining with previous data,this study collated the records of 132 butterfly species in the reserve.The data indicated that the composition of butterfly community changed obviously in different periods,which may have clues with climate changes.Moreover,fauna analysis showed that the butterfly community was dominated by 67 widespread species that accounted for 50.8%and 63 Palaearctic species of 47.7%,indicating that the butterfly community has a mix characteristic of widespread and Palaearctic species.This study provided a baseline information of butterfly diversity after the changes of the protected areas and will set a reference for future biodiversity monitoring in this nature reserve.
