摘要
“载畜量”过去解释为一定面积上的家畜放牧头数,这种理解不利于商品畜牧业形成。本文从调整畜种(品种)结构、开展季节畜牧业和对畜群结构(年龄、性别)进行调控等三个层次上,讨论拓展载畜量的阈值的途径。使“载畜量”变成草原放牧利用下所表现的生产力。
'Carrying Capacity' is defined as the number of livestock grazing on per unit of area. This comprehension is not favourable for the development of commodity animal husbandry.
The ways to expand the structure of carrying capacity are fully discussed in the present paper, in terms of adjusting the structure of livestock varieties, promoting seasonal animal husbandry and controlling the structure of cattle herds such as age and sex . Thus, this term will become favourablesin an assessment of pasture productivity under grazing conditions.
