本研究的目的是在居住区或住宅设计中，对植物对热环境影响的材料理解，以及植物空间在建筑环境中的地位。1.利用室外热环境仪和其他仪器，选择有植物和无植物的29个地点作为测试点进行测量。调查了夏季晴天热环境的实际状况。通过计算树木、草地、建筑物和天空对测量点的形状因子，了解每个测试点周围的情况.根据测量结果，对测量点进行主成分分析。描述变量是三个球体中心的温度，白天和黄昏的空气温度和风速。根据上述分析的结果，我们得到了主成分轴，可以解释为“影响 ...更多信息 日照、再辐射感度和风速。通过在“日照效应”和“再辐射感程度”的主成分轴上绘制各测点的主成分得分，考察了热辐射环境特征与形状状况的关系。从而明确了植物在建筑外热环境中的地位。结果表明：（1）除了被高热容材料包围的场地和地下通道等不暴露于天空的场地外，有植物的场地无论是晴天还是阴天都是负热辐射感受最强烈的场地。2）树荫下空间的热环境不受天气影响，从白天到晚上变化不大.根据室外热环境测量仪的测量值，得到了树木行下、有草坪的花园内和沥青停车场内的空气温度、太阳总辐射、平均辐射温度和风速等主要热环境因子。利用这些热力因子解释了2的研究结果，阐明了种植空间的特征。少

The aim of this study is to show the materials understanding of plants' effects on thermal environment in designing a residential area or house, and to make clear the situation of the space with plants in built environment. 1. 29 sites with and without plants were selected as test points for the measurements by using the outdoor thermal environmental meter and other ones. The actual conditions of the thermal environment on clear days in the summer time were investigated. The situation of the surroundings of each test site is understood by computing shape factors of trees, grass, buildings, and the sky to the measurement point.2. Based on the measured results,principal component analysis was carried out for the measurement points. Descriptive variables are temperatures at the centers of the three globes,air temperature and wind velocity in the day time and at dusk. According to the result of the above analysis, we obtained principal component axes which can be interpreted as "effects of … More sunshine","degree of reradiation feeling" and "wind velocity". The relationship between characteristics of thermal radiation environment nd shape situation was examined by plotting principal component scores of every test point on the principal component axes of "effect of sunshin" and "degree of reradiation feeling". Therefore, the situation of plants in the thermal environment outside buildings was clarified. The findings are as follows:1) The sites with plants are the ones where negative thermal radiation feelings are strong whether they are sunny or not, except for the sites which are surrounded by the materials with high heat capacity and not exposed to the sky like underground passage. This explains the effectiveness of plants on creating a cooler thermal environ-ment in summer.2) The thermal environment of the space in the shadows of trees is not influenced by weather, and changes little from the day to the evening.3. Air temperature, total solar radiation, mean radiate temperature and wind velocity - main factors of the thermal environment under the row of trees and in a garden with lawns and on an asphalt parking lot were obtained from the measure values of the outdoor thermal environmental meter. The characteristics of planted space were clarified by explaining the findings of 2 with those thermal factors. Less
