摘要
2004年1月～2006年1月，用小区绝对数量统计和访问法对弄岗自然保护区陇呼片与弄岗片冠斑犀鸟（Anthracoceros albirostris）的种群数量进行了调查。共记录到冠斑犀鸟7群22只，其中1群6只位于陇呼片内，6群16只位于弄岗片中。经分析，弄岗保护区的冠斑犀鸟现存种群数量至少为22只，比6年前增长14～16只。但与20年前相比，弄岗自然保护区冠斑犀鸟种群数量已显著下降，其原因可能是由于人类的偷猎和栖息地的减少。对广西冠斑犀鸟的保护提出了建议。
A survey of Oriental Pied Hornbill （Anthracoceros albirostris） had been conducted in Nonggang Natural Reserve by interview and field survey methods from Jan. 2004 to Jan. 2006. Seven flocks and 22 individuals were recorded in this survey. Among these records, one flock and 6 individuals were in Longhu part; six flocks and 16 individuals were in Nonggang parts. Therefore the population size of Oriental Pied Hornbill is at least 22 individuals. The result indicates that the population size has increased 14 to 16 individuals in the past six years. The result of Oriental Pied Hornbill decreased maybe ascribe to hunting and habitat reducing. In addition, some advice about the conservation on Oriental Pied Hornbill in Guangxi are given in this paper.
