The hot island phenomenon (熱島現象)was one starts from 1960 ages, appeared a topicality climate phenomenon in the world each place big city. Concrete, regardless of from early morning to sunset after, city part temperature all compared to peripheral locality unusual high. This phenomenon was photographs the Earth by the satellite from the upper air by infrared to discover in the picture city area temperature has the very obvious difference, looked like the city part on probably in a peripheral locality floating island. The unusual temperature rise main reason, comes from the building and the pitch sunlight regeneration, in the building air conditioning equipment which the city interior stands in great numbers the hot air which discharges, the city dome effect which trees' reduction produces. Because the temperature outdoes, therefore can appear the sudden rainfall. In recent years, the building to the upper air development, the rivers coast is covered unceasingly, all obstructs the flowing which keeps out the wind, intensified the city internal high temperature
