红腹锦鸡逃逸种群的春季栖息地选择研究

2018年和2019年春季，借助于野外红外触发相机技术，在浙江省下渚湖国家湿地公园对红腹锦鸡逃逸种群的栖息地开展调查研究.结果表明，逃逸的红腹锦鸡倾向选择中坡位、坡度中等(31.57±2.78°)的阔叶林与针叶林栖息，其乔木盖度较低(50±7%)和倒木数量较少(每10 m2根数为4.71±0.86)而落叶盖度较大(90±4%)，并具有优良的避风性和中等湿润度的土壤(p〈0.05或0.01)；而海拔、乔木数量、乔木均高、坡向、灌木盖度和均高、草本盖度、离水源距离及干扰距离等生态因子对其栖息地选择的影响不显著(p〉0.05).分析表明，逃逸的红腹锦鸡种群主要在食物资源丰富、视野较为开阔的林地栖息繁衍和建群，其栖息地选择能随环境条件的变化而有一定程度的改变，具有一定的环境适应性和选择可塑性.综上所述，逃逸红腹锦鸡的栖息地选择可能受食物、隐蔽性、气候、地理条件和障碍物的影响.

Studies on spring habitat selection of the escaped Chrysolophus pictus

The habitat of escaped Chrysolophus pictus was investigated with the help of field infrared camera in Xiazhu Lake National Wetland Park in the spring of 2018 and 2019. The results showed that the escaped Chrysolophus pictus tended to choose broad-leaved forest and coniferous forest at medium slope position with moderate slope angle (31.57±2.78°) with low tree coverage (50±7%) and small number of fallen trees (4.71±0.86 per 10 m2) while high deciduous cover (90±4%)， excellent wind shelter and medium moist soil (p〈0.05 or 0.01). However， the other ecological factors， such as altitude， number of trees， average height of trees， slope direction， shrub coverage， shrub average height， herb coverage， distance to water source and interference distance， had no significant effect on the habitat selection of the fleeing golden pheasant (p〉0.05). It was analyzed that the escaped Chrysolophus pictus mainly inhabited and established in the woodland with rich food resources and wide field of vision. Their habitat selection would change with the environmental conditions to a certain extent， and had certain environmental adaptability and selection plasticity. In conclusion， the habitat selection of the escaped Chrysolophus pictus might be affected by food， concealment， climate， geographical condition and obstacles in spring.
