Observations and Proposing Evaluation Method of Human Thermal Environment around River and Forest.

本研究的目的是通过实地观测，量化城市河流、城市街道、城市森林、城市商业区等城市基础设施周边的微气象特征，并为定性评价人类热感觉，特别是炎热夏季的热感觉提供新的指标。本研究的成果总结如下：(1)城市基础设施周边小气候：对城市河流（多摩河）、城市森林（明治神林）、城市街道（根246）和城市化地区（银座市）进行实地观测，评价其小气候特征。特别是在明治神社森林的实验还可以引导污染物吸收（空气净化），萜烯排放（提神）和CO2同化的评价。(2)人体热环境鉴定：在明治神社和多摩河的野外观测中，还进行了人体生理测量。提出了连接人的感觉与气象环境的新方法。(3)一种新的热感觉指标：在气候模拟器上进行了室内实验，研究了人体的生理反应和热舒适。提出了一种新的热感觉指标VTL=虚拟热负荷，并对其有效性进行了验证。

The purpose of this study was to quantify micrometeorological characteristics near around urban infrastructures such as urban river, urban street, urban forest, and urban business area by conducting filed observations, and also to make a new index for evaluating qualitatively human-thermal sensations, especially in hot summer season. Fruits of this study were summarized in the following points ;(1) qualification microclimate near around urban infrastructures : Filed observations in urban river (Tama river), urban forest (Meiji-shrine forest), urban street (Root 246) and urbanized area (Ginza city) were conducted, and their characteristics of microclimate were evaluated. Especially, the experiments in Meiji-shrine forest can also lead the evaluation of pollutants absorption (air purification), terpene emission (refreshment), and CO2 assimilation.(2) qualification of human thermal environment : In the field observation in Meiji-shrine and Tama river, human-physiological measurements were also conducted. The new methodology connecting the human-sensation and meteorological environments was proposed.(3) A new index of thermal sensation (VTL) : laboratory experiments were performed in a climate simulator to investigate human's physiological response and thermal comfort. A new thermal sensation index (VTL=Virtual Thermal Load) was proposed and it's validity was confirmed.
