贵州宽阔水国家级自然保护区红腹锦鸡分布范围及生境选择研究

Distribution and habitat selection of Chrysolophus pictus in Kuankuoshui National Nature Reserve

为深入了解贵州宽阔水国家级自然保护区红腹锦鸡分布范围及其生境选择利用情况,2017-2019年,基于红外相机陷阱技术对宽阔水保护区内红腹锦鸡开展调查研究,结果表明:1)保护区内红腹锦鸡较丰富,拍摄率高达1.91%,主要分布于保护区的核心区,缓冲区和试验区也有一定量的分布;2)坡位(x^(2)=19.633,df=2,P=0.000<0.001)、基质类型(x^(2)=17.163,df=1,P=0.000<0.001)、坡度(P<0.01)、距居民点距离(P<0.01)和距农耕地距离(P<0.01)对红腹锦鸡有极显著影响;植被类型(x^(2)=14.163,df=4,P=0.007<0.01)对红腹锦鸡有显著影响;其余因子对红腹锦鸡均无显著影响(P>0.05)。

In order to understand the distribution and habitat selection and utilization of Chrysolophus pictus in Kuankuoshui National Nature Reserve,an investigation on Chrysolophus pictus in Kuankuoshui National Nature Reserve was carried out based on infrared camera trap technology from 2017 to 2019.The results showed that:(1)there were abundant Chrysolophus pictus in Kuankuoshui National Nature Reserve,with a shooting rate of 1.91%;they mainly distributed in the core area of the reserve,while some distributed in the buffer area and the experimental area;(2)slope position(x^(2)=19.633,df=2,P=0.000<0.001),substrate type(x^(2)=17.163,df=1,P=0.000<0.001),slope gradient(P<0.01),distance from residential area(P<0.01)and distance from farmland(P<0.01)had extremely significant effect on Chrysolophus pictus i;vegetation type(x^(2)=14.163,df=4,P=0.007<0.01)had significant effect on Chrysolophus pictus;other factors had no significant effect on Chrysolophus pictus(P>0.05).
