川西北高原马麝(横断山亚种)的夏季生境选择

Habitat Selection of Moschus chrysogaster sifanicus in Summer in Northwestern Plateau, Sichuan Province

在野外调查的基础上,利用数量化理论处理分析数据,对川西北高原马麝(横断山亚种)夏季生境选择进行了研究。结果表明,影响马麝(横断山亚种)夏季生境选择的主要因子有植被类型、隐蔽条件、坡向和人为干扰,次要因子有食物丰盛度、坡度、坡位、水源和天敌干扰,其最适生境条件为隐蔽条件好、干扰少、主要位于阴坡的灌丛。

Based on the quantitative theory, the studies show that the key habitat selection factors of Moschus chrysogaster sifanicus in summer in northwestern plateau of Sichuan are vegetation type, shelter class, slope aspect and human disturbance,the secondary factors are food abundance, slope degree, slope position, water resource and natural enemy,and its most suitable habitat is shrubs on shaded slopes with better shelter class and less disturbance.
