龙栖山自然保护区蝴蝶群落多样性及区系组成

蝴蝶是生态质量和环境变化的重要指示生物。查明福建省龙栖山国家级自然保护区蝴蝶资源及其动态对龙栖山生物多样性保护和研究具有重要意义。通过2016-2018年对龙栖山自然保护区蝴蝶的持续调查和观测, 应用Shannon-Wiener指数及相对多度分析研究了蝴蝶的多样性、种群动态和区系成分。结果表明: 龙栖山自然保护区的蝶类有5科107属193种。在龙栖山样区设置的6条样线中, 小沛样线的属和种数均为最多, 共48属58种; 属于国家保护的蝴蝶有6种; 区系组成主要以东洋种成分(79.3%)为主, 广布种成分次之(21.2%); 蝴蝶优势种组成在不同年度间稍有变化, 持续稳定的优势种为矍眼蝶(Ypthima baldus)。

Community diversity and faunal composition of butterflies in the Longqishan Nature Reserve

Butterfly is an important indicator of ecological quality and environmental change. Finding out the butterfly resources and their dynamics in Longqishan National Nature Reserve in Fujian Province is of great significance to the conservation and research of Longqishan biodiversity. We analyzed the butterfly diversity, population dynamics, and faunal composition throughout the nature reserve using Shannon-wiener index and relative abundance and continuous observations over a three year period (2016-2018). We recorded five families, 107 genera, and 193 species of butterflies in the Longqishan Nature Reserve. Among the six sample lines in the Longqi Mountains area surveyed, the greatest number of genera and species was recorded on the Xiaopei sample line, with 48 genera and 58 species recorded in total. Six recorded butterfly species are under state protection. Overall, the faunal composition was dominated by Oriental species (79.3%) followed by widespread species (21.2%). The dominant butterfly species composition did not vary significantly between years. The continuously stable, dominant species recorded was Ypthima baldus.
