绿尾虹雉迁地保护现状及对策

open access: yes野生动物学报, 2019
通过对我国特产雉类绿尾虹雉野外种群状况和圈养繁殖状况研究的调查,对其迁地保护现状做了分析和总结。绿尾虹雉圈养繁育难点主要有:圈养与栖息地海拔和气候环境差异较大使圈养个体易患疾病,存活率低;圈养繁殖率低,繁育技术水平有待提高;圈养种群缺少基础建立者,导致近亲繁殖。本文针对以上难点提出了该物种今后迁地保护相应的对策:根据野外生态环境选择圈养场地,建立生态式笼舍和繁育场所;科学地进行繁殖管理,提高繁育水平和繁殖率;建立疾病防预体系和卫生防疫制度;开展技术交流与合作。希望能为今后绿尾虹雉圈养保护提供参考。

open access: yes, 2015
“家“字“从宀从豕“,具象地保留下人类生存方式的历史记忆,所谓无“豕“不成“家“,体现的是农耕文明的基本生存方式。通过对猪的圈养与驯化史的追溯可知,“豕“是农业文明特别是华夏农业文明的一个象征符号,“豕“与“家“的生养关系在饮食文化、节祭信仰等方面都多有体现。The Chinese character Jia( 家, home) contains two radicals, Mian( 宀)and Shi( 豕, pig).It is a vivid manifestation of the ...
