绵阳雏鳳山及周边冬·春季白颊噪鹛数量及分布

2009年11月～2010年4月,采用样线调查法对雏鳳山及周边环境冬春两季白颊噪鹛(Garrulax sannio)数量及分布进行了调查。共记录实体4 073只次,其中冬季2 003只次,春季2 070只次。结果表明,白颊在调查区均有分布,乔灌林的种群数量明显高于河道,其遇见率为37.167只次/(h.km),河道遇见率为12.615只次/(h.km),其他区域遇见率约为12.667～17.308只次/(h.km);春季数量略高于冬季,与生存和繁殖相关资源条件(食物、水分、隐蔽条件)较优越的生境其分布数量明显较多,干扰较大的公路沿线绿化林地有相当大的数量。最后,对此次调查研究方法的可靠性及其数量分布的差异进行了分析,同时对城市及近郊开展鸟类保护工作提出了建议。

Abundance and Distribution of Garrulax sannio in Winter and Spring in Chufeng Mountain and Its Surrounding Areas in Mianyang

The investigation on abundance and distribution of Garrulax sannio was conducted in Chufeng Mountain and its surrounding areas in winter and spring by line transect method from Nov.2009 to Apr.2010.Totally 4 073 Garrulax sannio were observed,including winter 2003 and spring 2 070.However,they were not distributed evenly in habitats.The population of arbor and shrubbery where the encounter rate was 37.167 met/(h·km) were higher than the riverway 12.615 met/(h·km) and the encounter rate of others remained at 12.667-17.308 met/(h?km);the population of ones in spring was higher than winter,the conditions of survival and breeding habitat such as food,water and concealed conditions were more favorable for their distribution,it also had a considerable distribution in road green belts where the interference was very serious.so we makes an analysis to the reliability of the research methods and the difference of abundance distribution,while give some suggestions to protect birds in urban and outskirts.
