人工林对海南鹦哥岭鸟类多样性的影响

Negative Effects of Plantations on Bird Diversity in Yinggeling Nature Reserve,Hainan Island

为了解在天然林中所种植的人工林对鹦哥岭鸟类多样性的影响,于2005年10月～2006年4月,分别采用样带法和雾网法,对海南鹦哥岭的原生林、次生林、人工林及其林缘的鸟类多样性进行了比较研究。野外记录到鸟类102种,其中栗腹矶鸫Monticola rufiventris、橙胸姬鹟Ficedula strophiata和黄雀Carduelis spinus 3种为海南鸟类新纪录。与原生林和次生林相比,人工林及其林缘的鸟类多样性很低,其中人工林最低。人工林不仅对鹦哥岭自然保护区的鸟类多样性具有非常大的负面影响,而且由于人工林的种植使天然林破碎化而产生的林缘与天然林林缘不同,鸟类多样性较低。

The effects of plantations on bird diversity in Yinggeling Nature Reserve, Hainan Island, China, was examined from October 2005 to April 2006, using belt transect count and mist net methods. A total of 102 bird species were recorded, of which three bird species （Monticola rufiventris, Ficedula strophiata and Carduelis spinus ） were new records for Hainan Island. Compared with the natural tropical primary and secondary forest, bird diversity in plantations and the forest edge was considerably lower, with the plantation having the lowest bird diversity. Habitat fragmentation caused by plantations has a negative effect on bird diversity in Yinggeling Nature Reserve.
