摘　　要：为了改善现有光气候区描述的不足,并研究中国典型光气候区光气候特性,利用太阳直射光、天空漫射光、地面总照度与大气层外照度的比率作为研究的参数。在12个典型光气候地区1 a光气候观测数据的基础上,通过P-G-D图表研究各地区的光气候状况。该方法能较直观、准确地反映出研究地的光气候特性,有利于比较各地区光气候参数之间的差异。通过对中国典型12个光气候区的光气候参量对比分析,初步得到了中国光气候区的分布趋势。In order to improve the deficiency of existing daylighting climate zones and investigate the characteristics of the typical daylighting climate zones, the ratio between direct light ,diffuse light , global illumiance and extraterrestrial horizontal illumiance were taken as parameters. On the basis of annual observation data of twelve typical light climates zone, daylighting climate of various regions was investigated by P-G-D diagram. This method could more intuitively and accurately reflect the characteristics of regions and be easier for comparing the difference between light parameters . Through analysis, the daylight distribution profile of twelve zones were obtained, with which it could be reference for daylighting design.
