动物生产的地境适应性

Adaptation of animal production to environment

动物生产应符合地境适应性原则。特定家畜总是在一定气候区域分布,其新陈代谢随环境变化而变化,使之呈现出不同的生产水平。大空间尺度、中等空间尺度和小空间尺度上均体现了地形对动物和植被分布的影响。草地农业系统中由地理位置、人类活动共同作用形成的位点在不同地区尺度水平上往往均居于系统发展的关键地位。地境因子中气候、土地和位点相互作用,各有侧重。这是进行养殖场空间布局时需要加以考虑的。

Animal production should be consistent with the principle of ground habitat adaptation.Specific animals are always distributed in a certain climatic regions.The metabolism creates different production levels with environment varying.Large spatial scale,medium scale and small spatial scale of space reflect the fact that the topography plays an important role in the distribution of animals and vegetation.In system,sites in scale levels of different areas formed by the geographical location and the role of human activities tend to be the key factor in the system development.Climate,land and sites in ground habitat factor interact,but have focuses.It is should be considered while programming the spatial layout of the livestock farm.
