摘要: 为了解白鹇(Lophura nycthemera)种群分布与栖息地斑块特征之间的关系,于1998年9月至1999年8月在浙江省古田山国家自然保护区及其外围地区对白鹇种群进行调查.通过羽迹法调查并估计斑块内局部种群数量的相对大小,分析斑块内植被及景观特征对斑块占有及种群相对密度大小的影响.结果表明,斑块面积、总盖度、乔木层盖度和灌木层高度等对斑块内有无白鹇出现影响显著,斑块面积大、总盖度及乔木层盖度高、灌木层高度高的斑块内白鹇出现率高,斑块面积大则局部种群的相对密度也大,两者间呈极显著正线性相关.

Abstract: To understand the relationships between the distribution of Lophura nycthemera population and the attributes of habitat patch,this paper investigated the population of L.nycthemera in the National Gutian Mountain Natural Reserve and its periphery area in Zhejiang Province from September 1998 to August 1999.The relative population density of L.nycthemera in each patch was determined by transect census with collecting molted feathers,and the effects of vegetation and landscape characteristics on the relative population density and patch occupancy were analyzed by statistic methods.The results showed that the occurrence of L.nycthemera was significantly affected by patch area,total cover,arbor cover,and shrub height.High frequency occurrence of L.nycthemera was observed in the patches with large area,dense total cover,dense arbor cover and high shrub height,and high relative population density was found in large size patches. There was a significant positive linear correlation between relative population density and patch area.
