海南俄贤岭地区陆生脊椎动物简报

Preliminary report of terrestrial vertebrates at Exianling area,Hainan

俄贤岭是海南岛面积最大片、垂直落差最大的石灰岩喀斯特地区,林相高大茂密,是海南最为典型、保存得最好的热带石灰岩原始林区。由于位处偏僻,过往对当地动植物了解不多,随着近年的深入调查,发现植物和无脊椎动物非常丰富,特有物种繁多。但是对俄贤岭及邻近地区的陆生脊椎动物所知极少,我们在2004～2006年间对俄贤岭及邻近地区进行多次简短考察,并在2007年3月进行了一次大型考察,记录到陆生脊椎动物(不含翼手目及鸟类)共12目21科32属33种;其中不乏国家保护动物如水鹿Cervus unicolor、珍稀物种如马来豪猪 Hystriix brachyura 及海南特有种如霸王睑虎Goniu-rosaurus bawanglingensis等。就我们简短的调查结果表明,虽然盗伐偷猎行为并未完全禁绝,俄贤岭仍保留了较丰富的脊椎动物资源,极具保护价值,有必要尽快加大保护力度。

With the most extensive limestone karst area,largest altitudinal range,and well-preserved forest, Exianling is the best example of tropical limestone forest area on Hainan Island.Due to its remoteness,very little was known about its fauna and flora.In recent years,surveys revealed a rich flora and diverse invertebrate fauna,with many rare and endemic species.However,the vertebrate fauna of Exianling and its surrounding area is almost unkn- own.An in-depth survey conducted in March 2007,augmented by various brief visits during 2004～2006,yielded a total of 33 species of terrestrial vertebrate fauna (excluding Chiroptera and birds)in 32 genera,21 families and 12 orders.These included protected species such as the Sambar Cervus unicolor,locally rare species such as the Malayan Porcupine Hystrix brachyura and Hainan endemics such as Goniurosaurus bawanglingensis (Squamata:Eublepharid- ae).Despite the fact that logging and poaching remains as real threats,our brief study indicates that Exianling has retained a rich vertebrate fauna,and better protection and enforcement is needed.
