甘肃则岔林区蓝马鸡种群密度调查

Population Density of the Blue-eared Pheasant in Zecha Forest,Gansu Province

采用样带调查法于2007～2008年对甘南则岔林区蓝马鸡的种群资源进行调查。2007年4～6月,蓝马鸡种群密度较低,为0.104～0.208只/hm2;2007年7～8月蓝马鸡群体数量略有增长,为0.162～0.236只/hm2;2007年12月(冬季),密度下降为0.148只/hm2;2008年5～8月,蓝马鸡群体种群密度呈增长趋势。综合2年资料,蓝马鸡的平均种群密度为0.171只/hm2。蓝马鸡种群数量与10年前的调查比较增加不明显,当地林管部门还需要加大蓝马鸡栖息环境的保护力度。

From 2007 to 2008,the population density of Blue-eared Pheasant in Gahai-zecha Nature Reserve was investigated by using line-transect method.The results showed that the population density was （0.104-0.208）/hm2 from April to June in 2007,and increased to （0.162-0.236）/hm2 from July to August in 2007.However the population density was decreased to 0.148/hm2 in December 2007.The population density increased gradually from May to August in 2008.In conclusion,the population density of the Blue-eared Pheasant was estimated to be 0.171/hm2.Compared with the data ten years ago,the population density was not increased obviously since nature reserve funded.Therefore,the habitats conservation of this pheasant should be put in practice by local forestry departments.
