【摘要】 大丰雉鸡领域的位置不是随机确定的,领域中的生境类型组成与整个研究区的生境类型组成之间存在很多显著差异.考虑到领域的独占性,我们试图通过确定“领域雄鸟实际可利用范围”的方法来排除个体间空间行为对领域雄鸟栖息地选择的影响,结果表明雉鸡对栖息地的选择性十分明显.雉鸡的领域由多种生境类型组成,雉鸡倾向于在多种生境的边缘占区.生境是否开阔、是否有较丰富的食物、较低层次的植被盖度、植物种类的多样性以及人类干扰等因素可能是影响占区雉鸡选择生境类型的重要方面.避免占区雄鸟之间的直接冲突、满足雄鸟求偶炫耀和保障自身生存是雉鸡领域的主要功能.更多还原

【Abstract】 Ring - necked pheasants territory sites are not randomly determined in Dafeng research area. There are many differences of habitat composition between the territories and the whole research area. When considered the monopolistic of territories, we tried to get rid of the individuals’ space behavior effects, which influenced territory males’ habitat selection, by determining actually available area for every territory male. The results indicated that the males’ habitat selectivity was still obvious. Territories were composed of diverse habitat types. Males tends to establish territories on the edge of several habitat patches. Openness, food resource, coverage of lower vegetation, diversity of plant species and disturbance of human are main aspects that affect male pheasants’ habitat selection. We also argued that avoiding directly conflict, meeting the needs of displaying and ensuring survival are the biological purpose of ring - necked pheasant s territory.更多还原
