| 2019年4-10月，在鸡公山自然保护区的核心区和实验区内不同生境、不同人为干扰程度的区域选取6条样线，对蝶类群落进行了观测研究。共记录蝴蝶3 431头，隶属于10科79属127种；其中蛱蝶科Nymphalidae的种类数最多，共23属36种；粉蝶科Pieridae和灰蝶科Lycaenidae为保护区优势科，菜粉蝶Pieris rapae (Linnaeus)、蓝灰蝶Everes argiades (Pallas)和苎麻珍蝶Acraea issoria (Hübner)为保护区优势种。保护区内蝶类群落的种-多度曲线呈正态分布模式，表明区内生态环境整体情况较好。不同样线中蝶类群落的种类、数量及多样性指标存在明显差异，无人类活动的样线Ⅴ和Ⅵ中蝶类群落的各项多样性指数均优于另外4条样线；适度人为干扰的样线Ⅰ、Ⅱ和Ⅳ中蝶类群落的各项指数均大于旅游景区样线Ⅲ的，且样线Ⅲ的优势度指数明显大于其他样线。各样线蝶类群落的种类数、个体数以及多样性指数的变化趋势与温度相一致，呈显著正相关关系；而与降雨量无显著相关性。由此可见，鸡公山保护区现有的旅游规模、森林经理和项目建设对蝶类群落产生了负面影响，但是适度的人类活动能在一定程度上延缓蝶类多样性的降低。 |

| To investigate the diversity of butterfly community and its influencing factors in Jigongshan Nature Reserve, we selected six transects in different vegetation habitats and interference areas. A total of 3 431 butterfly individuals were recorded, of which 127 species in 79 genera under 10 families were identified from April to October 2019. Among them, Nymphalidae had 23 genera and 36 species, with the most number of genera and species. Pieridae and Lycaenidae were the dominant family, with the most number of individuals. Pieris rapae (Linnaeus), Everes argiades (Pallas) and Acraea issoria (Hübner) were the dominant species in this area. The species-abundance analysis showed a normal distribution model, suggested a relatively stable ecological environment in the reserve. The species, individual number, diversity index, richness index, evenness index and dominance index of butterfly community varied significantly among different transects. In detail, butterfly diversity in the core zone was better than the other four transects with human disturbance. The characteristic indexes of transects with appropriate interference were higher than those of scenic area, and the butterfly community in scenic area had the highest dominance index. The species number, individual number and diversity index of butterfly in different transects varied significantly among different months, and showed the same trends as temperatures. Moreover, the numbers of butterfly species and individuals had a significant positive correlation with temperature, but no significant correlation with rainfall. In conclusion, the existing tourism scale, forest manager and project construction had negative effects on the butterfly community in the reserve, but appropriate interferences can delay the degradation of butterfly diversity. |
