    摘要:

    为了探明四川白水河国家级自然保护区及周边区域红腹锦鸡的种群状况及其栖息地特征,本研究于2018年采用样线法对该区域红腹锦鸡种群进行调查,基于占区雄鸟鸣声估算其种群密度,并采用样方法研究其微生境选择.结果显示:红腹锦鸡繁殖期的平均种群密度为5.300±1.086只/km2,推算研究区域内种群数量约为402只,其中保护区内约209只;红腹锦鸡偏好海拔较低、坡位靠下、靠近水源、植被原始、乔木层和灌木层发达、岩石和裸土盖度低的微生境.调查发现,红腹锦鸡主要分布于保护区海拔较低的实验区及周边,该区域旅游、资源采集等人为干扰严重,因此,建议在本区域内加强进山人员管理、合理开发旅游资源,以保护低海拔地区的红腹锦鸡种群及其栖息地.

    Abstract:

    To ascertain the population and habitat status of Golden Pheasant (Chrysolophus pictus) in Baishuihe National Nature Reserve and its surrounding areas in Sichuan province, transect surveys and call counting method were used to investigate the population density of Golden Pheasant, quadrat sampling method was performed to study their microhabitat selection during breeding season of 2018. The results showed that: the average population density of Golden Pheasant was 5.300±1.086 individual/km2 during the breeding season. It was estimated that there were about 402 in study area, of which about 209 were in reserve area. Golden Pheasants preferred to select microhabitat with lower altitude, lower slope position, closer to water resource, more primitive vegetation, better developed arbor and shrub stratum, and lower coverage of rock and bare soil. The survey found that Golden Pheasant was mainly distributed in the experimental area of the reserve with low altitude in protected area and its surrounding region, where was under intense human disturbance including tourism, herb medicine collection and so on. Therefore, to protect Golden Pheasant and its habitat, it is necessary to control human activities and develop tourism resources reasonably in low-altitude areas.
