【摘要】 采用鸣叫计数法和距离取样法,在海南霸王岭自然保护区,对海南山鹧鸪的种群密度进行了调查.2003年12月—2004年3月,在保护区东二保护站区域的天然林中记录到海南山鹧鸪的鸣叫个体8只,其种群密度为12只/km2.2006年12月—2007年1月,在该区域的原生林中记录到鸣叫个体20只,种群密度为9只/km2;在次生林记录到11只,其种群密度为6.5只/km2.2006年12月—2007年1月,采用距离取样法在原生林中遇见海南山鹧鸪个体33只,种群密度为9.3只/km2;次生林中遇见16只,种群密度为5.9只/km2.所有调查在人工林中都没有遇见海南山鹧鸪,也未记录到其鸣叫个体.与10多年前的调查比较,海南山鹧鸪种群在次生林中明显增多.这与该地次生林的恢复和人为干扰减少以及次生林中食物较丰富有关.更多还原

【Abstract】 A survey was conducted of the population density of Hainan partridge arborophila ardens in Bawangling Nature Reserve of Hainan, from Dec.2003 to March 2004, and from Dec.2006 to Jan.2007, using the calling count index and distance sampling method.The population density of Hainan partridge in the rain forest was 12 birds/ km2 during 2003—2004 , and 9 birds/ km2 in the primary forest and 6.5 birds the/ km2 in the secondary forest during 2006—2007 by means of the calling count index method.Using the distance sampling method, the population density of Hainan Partridge was 9.3 birds/ km2 in the primary forest and 5.9 birds/ km2 in the secondary forest during 2006—2007.No birds were found in the man-made forest.The conservation of Hainan Partridge in Bawangling Nature Reserve is good, and the secondary forest is becoming an important habitat for this species.更多还原
