中文摘要	对绵羊放牧行为的研究可为放牧管理措施提供依据,本研究以石河子市东湾镇一大滩和紫泥泉种羊场的绢蒿(Seriphidium)荒漠草地与放牧绵羊为研究对象,使用GPS对放牧绵羊的实时轨迹数据进行获取,通过ArcGIS对GPS数据进行分析处理,探究绵羊放牧过程中的位移时空变化规律。结果表明:放牧季节,绵羊行走的速度随着季节的移动呈先增加再趋于平缓后减小再增加的趋势;在一日的变化中,绵羊行走速度表现为先增加后减小再增加的趋势;随着坡度的增加,行走速度变化呈抛物线趋势,在坡度为43°时,速度最大。放牧绵羊的采食路径、行走速度在不同季节、不同时间差异明显,主要与草地植被生长、地形密切相关。
英文摘要	The study of sheep grazing behavior can a provide a basis for grazing management measures. The aim of this study was to explore the spatial and temporal variation in sheep displacement during grazing in Seriphidium desert grassland in Yidatan and Ziniquan sheep farms in Shihezi City. The real-time tracking data of grazing sheep were obtained by using GPS and analyzed by ArcGIS to determine the sheep grazing track and explore the variations in walking speed, time, and slope. The results showed that the walking speed of sheep increased at first, then tended to remain constant, and then decreased and increased in line with the seasonal movement of the grazing season. In the daily variation, the walking speed of sheep showed a trend of initially increasing, then decreasing, and then increasing again. As the slope increased, the velocity changed parabolically. At a slope of 43°, the velocity reached its maximum value. The feeding path and walking speed of grazing sheep were significantly different in different seasons and times, and were closely related to the growth of grassland vegetation and terrain.
