Abstract: The paper introduces the investigation conducted in the experiment site of the northern Qinghai lake region, and discusses the microclimate of the Kobresia meadow experiment site there. The alpine meadow region typifies the continental plateau climate-wide variance of temperature between day and night, frequent sunshine days,noticeable variance of periodic land surface temperature,strong solar radiation with a total of 5.866×106～6.704×106 kJ/m2 annually, and yet with damp soil and humid air. The characteristics of the microclimate and environment of the alpine meadow provide scientific basis to guide the agricultural and animal husbandry production of regions of similar climate conditions.

摘要： 文章介绍了海北高寒草甸试验区的野外考察现场和考察情况,并对青海海北高寒草甸矮嵩草草甸试验区的小气候考察结果进行了讨论,结果表明:高寒草甸地区具有明显高寒大陆性气候特征,日较差大,日照时间长,地表强度具明显的周期变化,太阳辐射强烈,全年总辐射量5.866～6.704×106KJ/m2,但较湿润,可为研究高寒草甸小气候特点、局地生态环境和指导生产实践提供科学依据。
