摘要
“生态系统管理”是畜牧业可持续发展的重要理论基础。放牧家畜饲养周期长 ,出栏率低 ,是制约高寒草甸畜牧业生产的最大瓶颈。因此 ,采取一系列生态系统管理措施 ,如建立人工草地、修建牲畜暖棚并进行牛羊舍饲育肥、退化草地恢复与重建、优化畜群结构和优化放牧强度等 ,实现畜牧业的集约化经营 ,是高寒草甸畜牧业持续发展的必由之路。
Ecosystem management”serves as an essential theoretical basis for sustainable development of animal husbandry.The longer raise period and lower slaughter rate constitute the important limiting factors for livestock production on high frigid meadows. The only road to sustainable development is to adopt a series of ecosystem management measures including the establishment of artificial grassland,construction of solar shed for animals,sheep fattening and yak fattening, restoration of degenerated grassland, optimizing structure of the animal population and grazing intensity,and realization of intensified management of livestock farming.
