(1)New techniques to investigate land cover and land use distributions were developed using Thermatic Mapper data from the satellite LANDSAT.The distribution of green coverage was characterised by a comparison of Japan and the Republic of Korea.(2)Principal component analysis were carried out on the data of air temperature distribution in the city in the early morning and the daytie in both summer and winter. As the result, air temperature distribution was affected very much by wind derection and wind speed, and was expressed by the quadric curve of the distance from sea shore.The cooling effects of vegetation in an urban area in summer were surveyed in park with green, on streets with roadside trees and in groups of trees around buildings. The data obtained in surveys were analyzed to clear the effects of vegetation on air temperature and thermal sensation.(4)Heat flux near the ground surface was measured by eddy correlation method. On asphalt pavement, heat flux was about 100W/m^2 and convective heat transfer coefficient was about 10W/m^2ﾟC

（1）利用LANDSAT卫星的Thermatic Mapper数据开发了调查土地覆盖和土地利用分布的新技术，通过与日本和大韩民国的比较，确定了绿色覆盖分布的特点。（2）对北京市夏季和冬季清晨和白天的气温分布资料进行主成分分析。结果表明，风向和风速对气温分布有很大影响，气温分布可用距海岸距离的二次曲线来表示.本文调查了夏季城市中有绿色的公园、有行道树的街道和建筑物周围的树木群的降温效果.分析了植被对气温和热感的影响。（4）用涡动相关法测量了近地表的热通量。在沥青路面上，热流密度约为100 W/m^2，对流换热系数约为10 W/m^2·C
