摘要
本文通过对草原区沙地放牧草地在畜牧业生产实践中出现大面积退化和沙化现象的分析 ,探讨了沙地放牧草地合理利用的途径 ,认为对于沙地放牧草地的保护 ,重点应放在草地的合理利用方面。通过以草定畜 ,合理调整载畜量 ;建立合理的利用制度 ;发展季节畜牧业 ;调整畜群结构 ,增加良种畜比例 ;以及改良天然草地 ,建立人工、半人工草地等措施 ,达到草原区沙地草地的可持续利用。
The degeneration and desertation of the sandy pasture in steppe zone were analysed and the better ways for it's utilization were discussed. The most important ways to protect the sandy pasture were using it reasonably. It is possible for a sustainable utilization of the sandy pasture in steppe zone in the way of regulation of the carrying capacity on the basis of forage production of the pasture, reasonable utilization system, development of the seasonal animal husbandry, improvement of the natural pasture, estabilishment of the artificial or semi-artificial pasture.
