We investigated the changes in temperatures in Takamatsu, Tadotsu and Osaka areas in Japan. Data of temperatures in Takamatsu (urban area: 1942-2009), Tadotsu (rural area: 1893-2009) and Osaka (metropolitan area: 1883-2009) areas around the Inland Sea in Japan was obtained from Japan Meteorological Agency. The changes in temperatures in three areas in Japan were analyzed and compared. By using data from 1942 to 2009, various parameters of temperatures were significantly correlated with years. The changes in mean temperature in August and in a year in Takamatsu area for 50 years were highest (August: 1.6°C, Year: 1.8°C) among three areas. In addition, correlation coefficient rate between years and the number of days over the level of 34°C in August in Takamatsu area was highest (r = 0.567, p < 0.0001). Parameters of temperatures were gradually increased with years in all three areas. The heat island effect in Takamatsu area was similar to Osaka area in Japan.
我们调查了日本高松、田布施和大阪地区的温度变化。从日本气象厅获得了日本内海周围高松（市区：1942-2009 年）、田布施（农村地区：1893-2009 年）和大阪（都市区：1883-2009 年）地区的温度数据。分析并比较了日本三个地区的温度变化。使用 1942 年至 2009 年的数据，温度的各种参数与年份显著相关。在这三个地区中，高松地区 50 年来 8 月和全年的平均温度变化最大（8 月：1.6°C，全年：1.8°C）。此外，高松地区 8 月 34°C 以上天数与年份之间的相关系数最高（r = 0.567，p < 0.0001）。所有三个地区的温度参数都随着年份的增加而逐渐增加。高松地区的热岛效应与日本大阪地区相似。
