摘要
为了解广东梅县阴那山省级自然保护区蝶类资源和物种多样性情况,2021 年 7-12 月利用样线法进行观测调查.结果表明,阴那山自然保护区共调查到蝶类 10 科、75 属、110 种;区系组成主要以东洋界为主,古北界和东洋界共有为辅;随海拔升高,蝶类群落属数、种数、个体数量、优势度指数、丰富度指数和多样性指数均表现为先增长后下降的单峰趋势,并均在 401～600 m达到最大值,高海拔地区蝶类群落的均匀度指数大于低海拔地区;相邻海拔地区蝶类群落的相似性较高,且高海拔与低海拔间蝶类种类存在明显差异.以期为阴那山省级自然保护区预测气候变化、保护蝴蝶资源和评价生态环境等提供基础资料和理论依据.
Abstract
The butterfly resources and species diversity in Meixian Yinna Mountain Provincial Nature Re-serve of Guangdong Province was studied by the line-transect method from July to December 2021.The results showed that 110 species of butterflies belonging to 75 genera and 10 families were investigated in the reserve;the fauna distribution type was mainly dominated by the Oriental,supplemented by the Pa-laearctic and Oriental;the number of genera,species,individuals,dominance index,richness index and diversity index of butterfly community at each altitude gradient showed a single peak trend of increasing first and then decreasing with the increase of altitude,reaching the maximum at 401-600 m,and the evenness index was higher at high altitude than at low altitude;the similarity coefficient was higher in the adjacent elevation gradient,and there were obvious differences between high altitude species and low alti-tude species.The results of this survey provided basic data and theoretical basis for predicting climate change,protecting butterfly resources and evaluating ecological environment in Yinna Mountain Provincial Nature Reserve.
