摘要
通过对海西州草地资源分布面积、鲜草产量、等级、退化状况等进行分析,认为海西州是全省荒漠类草地和低地草甸类草地的集中分布区,全州草地面积位居全省第二,但产草量位居全省末位,草地等级属中等偏下水平。天然草地中度以上退化草地面积占总退化面积的53.99%,且呈加剧趋势。海西州草地有一定的载畜潜力,但各县(市、行委)间放牧压力差异较大。发展畜牧业应结合各地区实际条件,因地制宜。改变现有的生产经营方式,大力发展人工草地,适当减少天然草地载畜量,实现草畜平衡。
This paper through analysis of The distribution area grassland resources,Fresh grass yield,grade and the Degradation statusthe in Haixi Prefecture. It is considered that the Haixi Prefecture is the concentrated distribution area of the province＇s desert grassland and Lowland Meadow Grassland. the area of grassland ranked second in the province,but grass quantity ranks the province＇s bottom,the rank of grassland is mediocre. The natural grassland moderate degraded grassland degradation area of the total area 53. 99%,and showed a tendency to aggravate. Haixi area has a certain potential for stocking,but the counties（ city） between grazing pressure difference. The development of animal husbandry should be combined with the actual conditions of the area,according to local conditions. Change the existing mode of production and management,vigorously develop the artificial grassland,appropriate to reduce the natural carrying capacity of grassland,grassland livestock balance.
