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.
