项目摘要

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.

本次研究项目的组织是为了促进土木工程领域热环境研究成果的交流。举行了一次面向公众的研讨会。花城分析了能源消耗，展示了污水热能利用的可能性。将中尺度气象模式应用于高府地区和东京地区。在利用现有条件对模型进行验证后，利用该模型对城市活动搬迁时的热环境进行了估算。森田准确地评估了城市地区的人工热排放。尽管难度很大，但还是利用汽车运输流量来评估交通部门的散热。塔迈研究了地理成分对城市热环境的影响。他还研究了土地利用变化对流域生态环境的影响。Uno开发了一个中尺度模式来模拟关东地区冬季的气候，并用观测数据进行了验证。北田对NOBI飞机的热环境进行了分析，发现从白天到晚上，山区产生的气流控制着气候，而人为土地利用变化对气候的影响相对较小。浅田测量了地表特性对热量收支的影响，发现路面保水可以缓解夏季高温。他还分析了琵琶湖周围的城市气候。井村应用三维封闭模型分析了福冈地区的热环境。他利用陆地卫星数据的输出得到了温度分布。建立了城市热环境综合评价的智能数据库。
