Observations of air and ground temperature and wind speed and direction were carried out in the alpine zone of Japanese high mountains, the Daisetsuzan Mountains, Mt.Yoteizan and Mt.Rishirizan in Hokkaido, northern Japan, and Mt.Sugorokudake and Mt.Minamidake in central Japan. The results are summarized as follows.1. the Daisetsuzan MountainsThe air temperatures at the wind-blown bare sites and at the forest line of 1,700m a.s.l. showed that the upper part of the Daisetsuzan Mountains belongs to a discontinuous permafrost zone and moreover to the alpine zone. The mean wind speed at the wind-blown site from October to April exceeds 10 m/s, and the prevailing wind direction is WNW.In autumn the lowest ground temperature is recorded in the Pinus pumila community, characterizing the upper part of Japanese high mountains, among all the plant communities. This indicates that the Pinus pumila community creates a peculiar environment for the ground temperature regime in summer.2. Mt.Yoteizan a … More nd Mt.RishirizanThe air temperatures at the wind-blown sites near the summits of Mt.Yoteizan (1,898m a.s.l.) and Mt.Rishirizan (1,719m a.s.l.) indicated that the climatic conditions of both sites corresponds to that of discontinuous permafrost zone. But a permafrost has not been confirmed through a ground temperature observation or a boring research.3. Mt.Sugorokudake and Mt.MinamidakeThe air and ground temperatures were observed at the wind-blown sites near the summits of Mt.Sugorokudake (2,860m a.s.l.) and Mt.Minamidake (3,033m a.s.l.). There is a difference in the altitude between the both mountains, but the conspicuous difference in the air temperature condition is not recognized between the two. The air temperatures indicated that there is a permafrost in the wind-blown bare ground near the summits. Permafrost, however, did not recognized through the ground temperature observation on Mt.Sugorokudake. On Mt.Minamidake, more observation and research are required to confirm that there is a permafrost or not. Less

在日本高山的高山地带、日本北方北海道的大雪山、羊蹄山和Rishirizan山以及日本中部的Sugorokudake山和Minamidake山进行了空气和地面温度以及风速和风向的观测。研究结果如下：1.大雪山在风吹裸露的网站和在森林线的1,700米a.s.l.的气温。表明大雪山上部属于不连续多年冻土带，而且属于高山带。10 ~ 4月平均风速超过10 m/s，主导风向为WNW。秋季，在所有植物群落中，日本高山上部的白松群落地温最低。这表明白皮松群落为夏季地温状况创造了一个特殊的环境.羊蹄山a ...更多信息 Yoteizan山（海拔1，898米）山顶附近被风吹过的地方的气温利尻山（海拔1,719米）表明两地的气候条件与不连续多年冻土区的气候条件相对应。但多年冻土还没有通过地温观测或枯燥的研究得到证实。杉岳山和南岳山在杉岳山（海拔2,860米）山顶附近的风吹地点观测了空气和地面温度。和南岳山（海拔3,033米）。这两座山的海拔高度不同，但两者之间的气温条件差异并不明显。气温表明，在山顶附近的风吹裸露的地面上有一层永久冻土。然而，通过对Sugorokudake山的地温观测，未发现多年冻土。在南岳山，需要更多的观察和研究来确认是否有永久冻土。少
