摘　　要：为探索绿孔雀的夜宿地选择模式及其成因,笔者于2007年3～4月和10～11月,在云南元江上游石羊江河谷绿孔雀的分布区内,采用样线法和样方法调查了绿孔雀的夜宿地生境,测定了19个生态因子。生态因子比较结果表明,夜宿地利用样方的坡度、乔木盖度、乔木胸径、落果密度、藤本密度与对照样方存在显著差异;夜宿地的海拔高度显著高于觅食地。判别分析结果表明,绿孔雀夜宿地和对照样地之间存在着明显的分化。逻辑斯蒂回归分析结果表明,绿孔雀选择坡度大、落果多、乔木的盖度和胸径大的地区作为夜宿地。隐蔽条件和食物等关键性生态因子的配置和可获得性决定了绿孔雀的夜宿地选择行为,而人为干扰压缩了其可利用的适宜生境,降低了生境的利用程度。We studied roosting site selection by green peacock(Pavo muticus imperator)by use of line transect survey and quadrant sampling in the Shiyangjiang Valley of upper Yuanjiang drainage in Yunnan Province,China,from March to April and October to November in 2007.We measured 19 habitat and landscape variables at occupied and randomly selected unoccupied quadrats.Slope gradient,degree of tree coverage,average diameter at breast height of trees,density of fruit drops and liana density were significantly different between occupied and unoccupied quadrants in autumn.Elevations of roosting sites were significantly higher than at foraging sites.Discriminant analysis showed that there were differences between characters of roosting sites and foraging sites.Logistic regression analysis showed that green peacock chose locations with higher elevation,steeper slope,abundant fruit,higher degree of trees coverage,and larger trees as their roosting sites in autumn.The allocation and availability of key ecological factors including good cover conditions and high quantity foods determined the habitat selection behavior of green peacock,and human disturbance also affected foraging site selection by green peacock.
