Collaborative research on infrastructure planning for improving urban heat environment

本研究项目是为了促进土木工程领域热环境研究成果的交流而组织的。召开了公开的研讨会，花木分析了能源消耗，展示了污水热利用的可能性。中尺度气象模式应用于甲府地区和东京。在对模型进行现状验证后，将模型应用于城市搬迁后的热环境评价。森田准确地评价了城市地区的人工排热。尽管存在很大的困难，但利用汽车运输流对交通部门的散热量也进行了评估。Tamai研究了地理成分对城市热环境的影响。他还研究了流域土地利用变化对生态环境的影响。Uno开发了一个中尺度模式来模拟关东地区冬季的气候，并用观测资料进行了验证。北田对野比平原的热环境进行了分析，发现山区产生的气流控制着白天到傍晚的气候，而人工土地利用变化对这一时期的气候影响相对较小。Asaeda测量了地表特性对热量收支的影响，发现路面蓄水可以缓解夏季高温。他还分析了琵琶湖周围的城市气候。井村应用三维闭合模型分析福冈地区的热环境。他利用地球资源卫星的数据得出了温度分布。开发了城市热环境综合评价智能数据库。

This research project was organized to promote exchange of research results on heat environment in the field of civil engineering. A symposium open to the public was held.Hanaki analyzed energy consumption with showing the possibility of utilization of sewage heat. Meso-scale meterological model was applied to Kofu area and Toyko. After validating the model with current condition, the model was used to estimate the heat environment when relocation of urban activity is done. Morita accurately evaluated artificial heat discharge in urban area. Heat discharge from transportation sector was also evaluated using automobile transportation flow in spite of great difficulty. Tamai studied the effect of geographical components on urban heat environment. He also studied on the impact of land use change on heal environment in river basin. Uno developed a meso-scale model to simulate climate in Kanto area in winter and validated it with observed data. Kitada analyzed heat environment in Nobi Plane, and found out that the air flow produced by mountain region governed the climate from day to evening time, when artificial land use change gave relatively little efects. Asaeda measured the effect of surface characteristics of land surface on the heat budget, and found out that pavement holding water can relieve high temperature in summer. He also analyzed urban climate around Biwa Lake. Imura applied three-dimensional closure model to analyze heat environment in Fukuoka region. He obtained temperature distribution by using the output of landsat data. Intellectual data base of comprehensive evaluation of urban heat environment was also developed.
