摘　　要：山地建筑受复杂地形影响而较普遍地存在采光不足的问题,而用采光系统以改善室内光环境是常见的做法。为探索不同地形关系下的山地建筑采光系统选取方式,本文以重庆市李子坝片区住宅建筑为例,选取朝向、楼层、间距、堡坎高度、堡坎长度等为变量进行模拟计算及数据分析。正交实验与皮尔森相关分析的结果表明,采光面和堡坎的间距与堡坎高度的比值“D/H”能较好反应不同地形环境下建筑各层的采光特点。基于此,本文提出了1套基于“D/H”指标来快速选取山地建筑适宜遮阳采光系统的方法,并进行了效果测试。With the influence of complex terrain,mountain buildings generally have the problem of insufficient lighting,and it is common practice to use a lighting improvement system to improve the indoor light environment.In order to explore the selection method of lighting systems for mountainous buildings under different topographic relationships,this paper,with the residential buildings in Liziba district of Chongqing as an example,selected orientation,floor,spacing,height of retaining wall,and length of retaining wall as variables to conduct simulation calculation and data analysis.The results of the orthogonal experiment and Pearson correlation analysis show that the ratio“D/H”of the distance between the lighting surface and the retaining wall to the height of the retaining wall can better reflect the lighting characteristics of each layer in buildings under different topographic environments.Based on this,this paper proposed a set of methods to quickly select suitable shading and daylighting systems for mountain buildings based on“D/H”index,and verified its effects.
