When using a computer to simulate the indoor natural light environment, ground reflected light is one of the influencing factors. Nanjing meteorological parameters used in this study, the researchers at overcast and clear sky, daylight portals direction and daylight opening distance from the ground floor reflected light on indoor lighting use Honeybee software. The results show that, in the clear sky conditions, ground reflected light will affect the natural light simulation in the low-rise interior of the building, the higher the surface reflectivity of greater influence, greater than on the north to the lighting of the room to the south affect the lighting of the room, and there is a limited range of influence and the ground area at the near window has the greatest impact.%在利用计算机模拟室内天然光环境时,地面反射光是其中的影响因素之一.使用南京市的气象参数,利用Honeybee软件研究在全阴天和晴天两种光气候下,采光口方向以及地面距采光口远近地面反射光对室内采光的影响.结果表明,在全晴天光气候条件下,地面反射光会对建筑低层室内天然光模拟产生影响,地面反射率越高影响越大,对北向采光的房间影响大于南向采光的房间,并且存在一定的有效影响范围以及近窗处的地面区域影响最大.
