在我国大中城市学位不足与建设用地紧缺的大背景下，对中小学校园运动场进行立体化设计能够形成空间的纵向叠加，从而释放大量建设用地，但运动场立体化同样也会产生一些新的设计难题，其中运动场地下部空间的自然采光问题又最为复杂，既面临照度是否足够的问题，又面临光线分布是否均匀的问题。国内外文献研究显示，当前国内外的立体运动场馆采光研究几乎空白，使得当前的建设存在一定的盲目性。基于以上考虑，该研究拟利用基于Rhino、Grasshopper、Ladybugtools三者构建的采光模拟平台的参数化光环境模拟技术，对不同形式的校园立体运动场馆下部区域的自然采光环境进行模拟，提炼出影响立体运动场下部空间采光的因素，包括运动场尺寸、架空层数、空间进深、功能布局、采光口位置、遮阳反光措施。通过对影响因素进行模拟分析，得出不同因素的影响机制，进一步提炼营造良好自然光环境的立体运动场设计对策，并以广州实验中学项目的学生活动中心的自然光环境优化实践形成研究反馈，从而验证了研究的有效性。

Under the background of insufficient school places and shortage of construction land in large and medium-sized cities in China, the three-dimensional design of primary and secondary school campus sports fields can form a vertical superposition of space, thereby releasing a large amount of construction land. However, the three-dimensional design of sports fields will also lead so some new design problems. Among them, the most complicated is the natural lighting of the lower space of the sports field, which facing both the problem of whether the illumination is sufficient and the problem of whether the light distribution is uniform. Domestic and foreign literature research shows that the current research on the lighting of three-dimensional sports venues at home and abroad is almost blank, which makes the current construction somewhat blind. Based on the above considerations, the study simulated the natural lighting environment of the lower area of different forms of campus three-dimensional sports venues with the parametric light environment simulation technology of the lighting simulation platform built based on Rhino, Grasshopper and Ladybugtools. And it extracted the factors affecting the lighting of the lower space of the three-dimensional sports field, including the size of the stadium, the number of overhead layers, the depth of the space, the functional layout, the location of the lighting port, and the sunshade and reflection measures. By simulating and analyzing the influencing factors, the influencing mechanisms of different factors were obtained, and the design strategies for three-dimensional sports fields to create a good natural light environment were further refined. The research feedback was formed based on the practice of optimizing the natural light environment of the student activity center of the Guangzhou Experimental Middle School project, thereby verifying the effectiveness of the research.
