潇水河永州零陵段沿岸蝙蝠物种多样性调查

Preliminary Survey on Bat Diversity along Xiaoshui River Coast in Lingling Section of Yongzhou,Hunan Province

2011年5月—2013年8月对潇水河永州零陵段沿岸蝙蝠物种多样性进行了初步调查。共记录到蝙蝠8种,分属3科5属。从分布型看,东洋型种类占多数(62.5%);从种群数量看,东亚伏翼Pipistrellus abramus与大蹄蝠Hipposideros armiger占优势,斑蝠Scotomanes ornatus数量最为稀少。区域内蝙蝠喜栖于竹丛、树冠、岩壁、洞穴、民居与古建筑等处。上、下游所栖蝙蝠种类存在差异,但均喜好在水体与植被交接处活动而形成活动聚集地,且洞穴冬眠型蝙蝠的年活动周期较房屋冬眠型蝙蝠的短。调查结果增加了对潇水河沿岸蝙蝠生存现状的了解,可为进一步开展蝙蝠研究和保护提供参考。

A preliminary investigation on bat diversity along Xiaoshui River coast in Lingling section of Yongzhou was conducted from May 2011 to August 2013. A total of 8 species of bat which belonged to 3 families and 5 genera were recor- ded, and the distribution pattern of Oriental accounted for the majority （62.5%）. Pipistrellus abramus and Hipposideros ar- miger were the dominated population while Scotomanes ornatus was very rare. Bats preferred bamboo clump, tree canopy, cliff, cave, vernacular dwelling and ancient architecture. Although the bat species between the upstream and downstream were different, the “activity centers” of the bat from both areas would be formed nearby the water and vegetation. The vege- tation and cave hibernating bats showed a shorter activity period than those of house hibernating ones annually. These results increased our understanding of current survival status of bats and provide reference for long-term and effective protection for bat along Xiaoshui River coast.
