The Population Dynamics of Breeding Ring-necked Pheasant in the Secondary Broad-leaved Forest of Jilin Province

In order to further understand the population dynamics of ring-necked pheasant Phasianus colchicus in secondary broadleaved forest,and provide theoretical basis for conservation,the population density of ring-necked pheasant was surveyed in Zuojia Nature Reserve(Jilin province) at breeding seasons during 2007 ~ 2012.The results showed that the annual fluctuations of ring-necked pheasant population density was in range of 0.037 ~ 0.084 ind./ hm2.Finally,snow thickness and low temperature might be the key factors that affected the population fluctuations of ring-necked pheasant.
