摘要:

掌握麋鹿种群冬季卧息地的微生境特征,可为冬季麋鹿种群的科学保护和有效管理提供理论依据。2011年12月—2012年2月,通过对61个利用样方和70个对照样方的比较调查,研究了湖北石首麋鹿国家级自然保护区内麋鹿冬季卧息地微生境选择。结果表明,湖北石首麋鹿国家级自然保护区内麋鹿冬季主要选择在食物丰富、植被盖度大、隐蔽度高的生境卧息。主成分分析表明,影响冬季麋鹿卧息地微生境选择的决定性因子是食物因子、温度因子、舒适因子。本研究分析了麋鹿种群对冬季卧息地生态因子选择的要求和原因,对麋鹿自然野化、种群就地与迁地保护均具有十分重要的意义。

Abstract: To understand the winter bed-site microhabitat characteristics of Pére David’s deer (Elaphurus davidianus) can provide theoretical basis for seeking strategies to scientifically protect and effectively manage E. davidianus in winter. In this paper, an investigation was conducted in 61 E. davidianus bedsite quadrants and 70 control quadrants in Hubei Shishou Milu National Nature Reserve from November 2011 to February 2012, aimed to understand the winter bedsite microhabitat selection by E. davidianus in the Reserve. The E. davidianus preferred the habitats with richer food, higher degree of vegetation cover, and better shelter for bedding down in winter. The principal component analysis showed that food richness, ambient temperature, and comfort index were the key factors affecting E. davidianus bedsite microhabitat selection. This study analyzed the reqirements of E. davidianus for the ecological factors of winter bedsite microhabitat, which would help to the insitu and ex-situ protection of wild E. davidianus population.
