摘　　要：本文通过对甘肃平凉地区窑洞采光的具体测量,分析了采光影响因素,提出了改善采光的设计方法和改造措施。首先,参考不同窑洞的照度,综合分析了光气候、窑洞朝向、口部构造、窑内空间设计、窑洞进深及窑内表面材料光反射等因素对采光量的制约。其次,完善适用于窑洞的天空照度模型,提出了窑内工作面综合照度公式,计算分析表明室外环境是影响采光的首要因素,采光口高度、透光材料及窑内表面反光材料对采光量的影响较大。最后,提出了窑洞在选址、设计、施工和室内装饰等方面的改善措施。In this paper, based on the daylighting measurement of cave dwellings in Pingliang area of Gansu, the influence factors of daylighting were analyzed, and the related design and improvement measurements for enhancing the daylighting effect were provided. Firstly,the constraints of influence factors on cave illuminance were discussed,including light climate, cave orientation, hole structure,interior space design, indoor depth and internal surface material, etc. Secondly, with the improved sky illuminance model suitable to cave dwellings,the synthesized illuminance equation for working surface was presented. It was found out that the outdoor environment was the most important factor, and the height of daylighting openings,the transmission material and the reflecting material of internal surface had relatively larger influence on daylighting quality. Finally,improvement measurements of site selection,design, construction and interior decoration were pointed out.
