摘 要：
充分了解蒙新河狸(Castor fiber birulai)对栖息地的选择是保护计划的基础,也是确保濒危物种得到妥善管理的关键。2015年秋季和2016年春季,以新疆布尔根河狸国家级自然保护区栖息的蒙新河狸为研究对象,采用痕迹调查法,研究了蒙新河狸制作气味堆及其与周围生境因子的关系,探讨影响蒙新河狸在制作气味堆时主要选择的生境特征。结果表明:春季,蒙新河狸气味堆平均长度为0.20 m、宽度为0.18 m、高度为0.06 m,秋季气味堆平均长度为0.15 m、宽度为0.08 m、高度为0.04 m,秋季气味堆的宽度和高度明显低于春季。在制作气味堆时,蒙新河狸偏好选择距离较近的苦杨(Populus laurifolia)、毛枝柳(Salix turanica)等乔木和高大灌木林,对河流特征的选择是距河岸(0.1~0.4 m)和水边(0~1 m)距离均较近,蒙新河狸选择远离人类活动、受人为干扰强度较小的生境制作气味堆。本研究结果为蒙新河狸栖息地的恢复提供指导。

摘 要：
Understanding habitat selection is fundamental to designing conservation programs and especially critical for ensuring endangered species.We investigated the habitat selection for a rare subspecies of the Eurasian beaver,Castor fiber birulai.Habitat characteristics of preferred scent mounts in Xinjiang Burgen Beaver National Nature Reserve were examined in the fall of 2015 and spring of 2016.The average length,width and height of the scent mounts used in spring were 0.20,0.18,0.06 m,and 0.15,0.08,0.04 m in autumn,respectively.The width and height was significantly lower in autumn than in spring.Beavers demonstrated a preference for creating scent mounts in areas that were closer to large trees and tall shrubs such as Populus laurifolia and Salix turanica,closer to river edges and banks and further from areas of human disturbance.Our findings provided managers with key insights to guide habitat restoration and protective measures to ensure this rare population of beavers continues to increase.
