| Outline of Final Research Achievements |
In order to evaluate the subsurface warming on phenology such as cherry blossom blooming, the long term records of soil temperature and cherry blossom blooming were analyzed. The records at 103 locations over the Japan show the 5 day earlier of blooming during the last 50 years. The cherry blossom blooming in Tokyo, Osaka and Nagoya were much faster than other locations in Japan, which shows the heat island effect due to urbanization. Soil temperature at the depth of 50 cm show the most highest correlation with cherry blossom blooming. The soil water content and chemistry were also analyzed related to the cherry blossom blooming.
