摘要
为了进一步认识次生阔叶林环颈雉的种群变化规律,为该物种的保护提供理论依据,于2007~2012年的3~6月,在吉林省左家自然保护区,采用样方调查法对环颈雉种群数量进行了调查。结果显示,环颈雉繁殖期的种群数量年波动范围在0.037~0.084只/hm2之间。经过分析表明：积雪厚度和严寒可能是影响其数量变化的重要因素。
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.
