Abstract This paper presents an approach for a quantitative analysis of movement patterns of nomadic households based on GPS trajectories. We distributed GPS loggers to 400 Mongolian herder households who carried them over a 9-month period, continuously recording position data every 30min. A total of 142of the resulting trajectories fulfilled our data quality criteria and were considered during the analysis. Based on this data, we derive summary indicators describing key parameters of the households’ mobility including measures of distance and number of movements as well as shape characteristics of the trajectories. We conduct an explorative statistical analysis of these summary indicators to investigate patterns in the nomadic mobility. We identify three movement strategies based on the number of different campsite locations and the distances traveled between campsites. We also compare the results to the existing literature on the mobility of Mongolian herders. Our findings show that GPS-based studies present a suitable framework to quantitatively analyze different movement strategies of nomadic herders.

基于 GPS 轨迹的蒙古族游牧家庭运动模式

摘要 本文提出了一种基于 GPS 轨迹定量分析游牧家庭运动模式的方法。我们将 GPS 记录仪分发给 400 户蒙古牧民，他们在 9 个月的时间里携带它们，每 30 分钟连续记录一次位置数据。总共 142 条所得轨迹符合我们的数据质量标准，并在分析过程中予以考虑。基于这些数据，我们得出了描述家庭流动性关键参数的汇总指标，包括距离和移动次数的度量以及轨迹的形状特征。我们对这些汇总指标进行探索性统计分析，以研究游牧流动模式。我们根据不同露营地位置的数量和露营地之间的行进距离确定了三种移动策略。我们还将结果与有关蒙古牧民流动性的现有文献进行了比较。我们的研究结果表明，基于 GPS 的研究提供了一个合适的框架来定量分析游牧民的不同运动策略。
