摘  要:
2007~2010年,在甘肃岷山地区开展了羚牛的调查研究,为了清楚了解羚牛对栖身地的选择性,研究人员选用Vanderloeg选择系数和Scavia选择指数的估算数据进行研究。结果显示,羚牛的栖息环境明显受到坡位、坡度、海拔、植被类型及植被起源的影响,其对20°~30°坡度并且处于上坡位的地理环境选择性强;而在坡向的选择性上不具明显偏好。活动范围集中在2 500 m以下的海拔区间,尤为偏好1 500~2 000 m的海拔区间;喜欢栖息于针叶林和针阔混交林的环境中,并且对原始森林具有明显偏好,其次为次生林。在数据分析及其他羚牛栖息地选择的因素组合的基础上,本文探讨了羚牛生境选择的生态因子的影响因素。

摘  要:
Investigation on Budorcas taxicolor has been made in Minshan, Gansu form 2007 to 2010. Vanderloeg coefficient and Scavia index were choosen to study the habitat of Budorcas taxicolor. The result is the habitat of Budorcas taxicolor was significantly affected by the slope, elevation, vegetation types and forest origin. Budorcas taxicolor has strong selectivity form 20° to 30° slope in the upper position of the geographical environment. And the selectivity on the aspect of the slope is not obvious. The range of activities is at the altitude below of 2 500 meters, especially between 1 500 m and 2 000 m. And it has a clear preference for the virgin forest, then for secondary forest. Based on the analysis of habitat selection factors on Budorcas taxicolor, this paper discussed the influencing factors of the ecological factors in habitat selection on Budorcas taxicolor.
