In order to estimate the temperature relationship between the green space in the city and its land cover, long term temperature was observed continuously in the 11 parks (Imperial Palace, Meiji Jingu and Yoyogi park, Shinjuku Imperial Gardens, Shizen-Kyoikuen, Koishikawa Botanical Garden, Koishikawa Kourakuen Garden, Shiba park, Toyama park, Rikugien Garden, Shinjuku ward Kansenen park, Minato ward Prince Arisugawa Memorial park) in Tokyo in the summer of 2006.As a result, the following results were obtained.1) Temperature data in the major green parks in Tokyo were obtained based on the field observations. The climatic effects of green spaces in the city for thermal conditions became clear. For example, the temperature difference between the inside and outside of the green spaces in summer season was at most about 5 degree Celsius.2) The temperature difference between the inside and outside of the green space was approximated by the curve of the logarithm of the gross area of the green space or the forest area of the green space. This study could contribute the SLOSS (Single Large Or Several Small) problem, which is a problem in discussing the thermal effect of the green space in the city in recent years. Moreover, this research proposed a new index based on the size and the rate of the forest area, and that was able to explain the temperature difference between the inside and outside of the green spaces.3) The time-series behavior of the magnitude of the land cover's contributing rate of the temperature difference was shown by the multiple regression analysis based on the higher time resolution observation in this study.

为了研究城市绿色空间与土地覆盖之间的温度关系，对11个公园进行了长期连续的温度观测（皇宫、明治神宫、代代木公园、新宿御苑、四善教育园、小石川植物园、小石川公园、芝公园、富山公园、陆园、新宿区观音园、结果表明：（1）通过野外观测，获得了东京主要绿色公园的温度数据。城市中绿色空间对热条件的气候效应变得清晰起来。例如，夏季绿色空间的内部和外部之间的温差最多为约5摄氏度。2）绿色空间的内部和外部之间的温差由绿色空间的总面积或绿色空间的森林面积的对数的曲线近似。本研究可为近年来城市绿色空间热效应研究中的SLOSS（Single Large Or Several Small）问题提供参考。此外，本研究还提出了一个基于森林面积大小和森林覆盖率的新指标，该指标能够较好地解释绿色空间内外的温差。3）基于高时间分辨率观测数据的多元回归分析，揭示了土地覆盖对温差贡献率大小的时间序列行为。
