人为干扰对壶瓶山国家级自然保护区蝴蝶物种多样性的影响

为了解人为干扰对壶瓶山国家级自然保护区(以下简称壶瓶山保护区)蝴蝶物种多样性的影响, 调查组于2017-2018年间采用样线法抽取5条样线对壶瓶山保护区的蝴蝶群落进行调查研究, 分析了人为干扰对蝴蝶发生规律的影响, 并比较了壶瓶山保护区中不同程度人为干扰情况下的蝴蝶发生差异。本调查共观测到蝴蝶6,711只, 隶属5科19亚科119属190种, 各样线的优势种主要有宽边黄粉蝶(Eurema hecabe)、东方菜粉蝶(Pieris canidia)、酢浆灰蝶(Pseudozizeeria maha)、宽带凤蝶(Papilio nephelus)等。轻度干扰情况下物种多样性最高, 其次为无干扰条件, 而中度干扰情况下蝴蝶物种多样性最低, 即小规模的耕作-居住环境有利于蝴蝶的聚集, 而增加现有的人为干扰程度或扩大干扰范围, 可致使群落中蝴蝶物种数减少、优势类群数量增加。

Influence of human disturbance on butterfly diversity in the Hupingshan National Nature Reserve

In order to understand the impact of human disturbance on butterfly diversity in the Hupingshan National Nature Reserve, we surveyed butterfly abundance in Hupingshan between 2017 and 2018, and analyzed human impacts in the region for the same time period. We compared differences in butterfly assemblages between three different levels of interference: non-interference, mild interference and medium interference. The results showed that of a total of 6,711 individuals observed, which belongs to 5 families, 19 subfamilies, 119 genera, 190 species represented. The highest species diversity was under mild interference, but the lowest diversity was under the medium interference. We conclude that small-scale farming-living environments are conducive to butterfly aggregations. If the existing level of human disturbance or the range of interference is increased, species represented in the butterfly community structure may decrease and the number of dominant species/groups may increase.
