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.
