摘要
2005年4～6月,作者在辽宁省实验林场、灯塔市铧子林场和建平县罗福沟乡对环颈雉种群密度进行了调查,调查方法采用样带法。辽宁省实验林场环颈雉种群密度为2.0只/km^2,灯塔市铧子林场种群密度为3.2只/km^2,建平县罗福沟乡种群密度为6.8只/km^2。造成环颈雉种群密度差异的因素主要是生境质量、猎捕压力和天敌数量。辽宁省调查地区的环颈雉种群密度明显低于其他省市和欧美地区,应采取加强宣传教育,保护栖息环境等措施。
From April to June, 2005, the population density of the ring- necked pheasant in Liaoning province was surveyed in following localities： Experiment Forestry Center of Liaoning Province, Huazi Forestry Center of Dengta City and Luofugou Forestry Center.Results of the survey were： in Experiment Forestry Center, 2 ind./kin^2, in Huazi Forestry Center, 3.2 ind./kin^2 and in Luofugou Forestry Center, 6.8 ind./kin^2 .Factors influencing the difference were quality of the environment, hunting stress and number of natural enemies. Obviously, the population density of ring - necked pheasants in Liaoning was lower than those in other provinces and other countries abroad, so conservation strategies to recover its population were discussed.
