摘要
1990—1998年和2006—2015年每年对广东省南岭国家级自然保护区蝶类进行区系调查,结果表明,南岭共有眼蝶科68种,其中东洋区共57种,东洋区属主导分布型;中国华南、西南、华中区的共有种共50种,其它分布区种类少,说明南岭眼蝶与南岭植物一样主要属亚热带区系;眼蝶科中的黛眼蝶属有29种,超过云南、海南、台湾、福建省等地的黛眼蝶属种数。2012—2015年对南岭南北坡不同海拔的蝶类分布进行了研究,共发现眼蝶39种669头,其中南坡32种417头,北坡23种180头,山顶5种72头。在区系组成上,南坡拥有更多的南亚热带至热带的眼蝶种类;在海拔分布上,南北坡栖息于中海拔(1 000~1 100 m)森林中的眼蝶种数比低海拔(500~600 m)多。造成眼蝶南北坡分布差异的可能原因是南坡冬季温度高于北坡,且南坡植物区系中拥有更多的热带广布成分;而造成中海拔眼蝶种数较多的原因是该区域人为活动较少、原始植被保留比较完整。
Fauna investigation of Satyridae in Nanling National Nature Reserve（NNNR） had been conducted during 1990—1998 and 2006—2015. Records show that there are 68 satyridae species in NNNR, of which 57 species belong to Oriental realm and 50 species are co-existent in South China, Southeastern China and Central China. It is indicated that NNNR＇s Saturidae faunal elements, like its floral elements, are mainly subtropical. 29 species of genus Lethe were found in NNNR, which exceeds those found in the province-wide of Yunnan, Hainan, Taiwan and Fujian,etc. A four-year line transect survey on both south and north slopes with different altitudes in Nanling Mountain was taken from 2012—2015, it recorded 669 individuals of 39 Satyridae species, of which 417 individuals of 32 species were found on the south slope, 180 individuals of 23 species on the north slope, and 72 individuals of 5 species on the mountaintop. Results of the investigation further revealed that more tropical and subtropical satyridae species were found on the south slope, and on both slopes the numbers of Satyridae species in forests at 1 000—1 100 m a.s.l.（above sea level） is larger than those in forests at 500—600 m a.s.l. One reason is that the winter temperature on the south slope is higher than that on the north slope, and another is that forests at 1 000—1 100 m a.s.l. are less disturbed than those at 500—600 m a.s.l.
