Meteorological and ecological investigation of pastoral animal husbandry in Mongolia

为了解草地畜牧业知识，对蒙古国北部布尔干州森林草原进行了气象、生态和人类学研究。结果如下：1)通过对山下冬令营和盆地底部夏令营的逐时温差观测发现，冬季牧民的冬令营位于盆地冷湖上方坡面的热带。从体温环境的角度说明了冬令营所在地的气象条件对家畜的有利条件。2)通过比较流动羊群和静止羊群绵羊和山羊的体重，发现流动羊群的增重幅度较大。3)人类学研究表明，位于城市郊区的研究区人口稠密，牧民倾向于利用他们在郊区的居住位置来最大化他们的现金收入，这是当今蒙古典型的牧民策略之一。

To investigate the knowledge of pastoral animal husbandry, the meteorological, ecological and anthropological researches were carried out in the forest steppe of Bulgan prefecture in northern Mongolia. Results are as follows : 1) From the observation of the hourly temperature difference of the winter camp at the foot of mountain and the summer camp at the bottom of the basin, it was mentioned that the winter camp of the herders are located at the thermal belt of the slope above the cold lake of the basin during winter. It was also shown how the meteorological condition of the location of winter camp is favorable for livestock from the view of the body temperature environment. 2) By comparing the body weight of sheep and goat in mobile and sedentary herd, it was shown that the weight increase is larger in mobile herd. 3) Anthropological research showed that research region, which was located at suburban area of a city, was densely populated by herders who tended to maximize their cash income by utilizing their living location at suburban area, as one of the typical herding strategies in today's Mongolia.
