中文摘要：

从福建客家土楼民居的建筑布局、形式和材料等建筑设计方面入手,分析福建土楼的建筑光环境.选择该地区典型圆形土楼建筑——福建南靖＂怀远楼＂作为实验数据的采集点,采取实地测试的方法研究单体土楼的光气候环境.研究结果表明：福建圆形土楼整体建筑的被动采光性能与居民的生活习性结合良好,具有良好的生态适应性能;在居民白天活动频繁的区域的太阳直射光和反射光照度充分,利于居民活动;土楼独特的空间形式和建筑材料使得其内部光环境的亮度对比度适中,减少了眩光级的可能性,光环境舒适度高.

英文摘要：

Based on the layout,form and materials of Fujian Hakka earth Buildings,the light environment was analyzed.Investigating Huaiyuan Building by on-site testing,one of the typical circular earth buildings in Nanjing Fujian,the experimental data were obtained to study the light environment of single building.The results show that： the passive daylighting performance of the whole circular Hakka house is consistent with the living habits of the residents,the ecological adaptability is benign;the intensity of both direct and reflected sun light is sufficient in the region for the resident frequent activities;the unique form of space and building materials of Hakka house moderate both the brightness and contrast of internal light environment,reduce the possibility of glare,and upgrade the comfortable degree of light environment.
