摘要
对甘肃省天祝县天然草地资源类型、分布规律和特点及生产力进行分析和总结。结果发现,该区天然草地主要有温性草原、山地草甸、高寒草甸、灌丛草甸和疏林草甸5类;不同地区、年际和季节间的草地生产力与营养成分差异很大,草地饲用植物种类多,产量低,品质差。建议综合利用草地培育措施,实行草畜系统的半放牧半舍饲经营,以恢复草地植被,发展草地畜牧业。
The types, distribution, characteristics and productivities of rangelands at Tianzhu County were analyzed and summarized. There are five types of rangelands at Tianzhu. They are mountain steppe, mountain meadow, alpine meadow, alpine shrubby tussock meadow and sparse forest meadow, respectively. The results from the study showed that productivities and nutritional contents of the rangelands were varieties in different areas, inter-annual and seasons. The species of forage plants of rangelands at Tianzhu County were very abundant, but their yield and quality were very poor. The study suggested that Tianzhu should utilize comprehensively measures of cultivating rangelands and take the method of combining grazing with dry-lot feeding to manage the system of pasture and livestock, so as to recover vegetation of rangelands and develop rangeland animal industry.
