| 摘要: |
| 根据日照理论和空间几何理论，对玻璃幕墙光污染特征进行计算分析。结果表明，南向玻璃幕墙光污染发生在冬至和春秋分，冬至以中等污染为主，上下午持续时间长；春秋分以轻微污染等级为主，上下午持续时间短；北向玻璃幕墙全年无光污染；其他朝向玻璃幕墙光污染全年均有，冬至主要在南至东的朝向，春秋分在南至东北朝向，夏至除南北朝向外所有朝向；光污染持续时间受朝向影响，冬至大，春秋分和夏至小。光污染影响区域大小、位置随朝向变化，冬至剧烈，春秋分和夏季缓和且稳定。 |

| Abstract: |
| According to the theory of sunshine and space geometry，the characteristics of light pollution of glass curtain wall are calculated and analyzed. The results show that the light pollution of glass curtain wall toward the south occurred in the winter solstice and equinoxes，winter solstice to secondary pollution，long duration; equinox to slight grades，short duration; the glass walls toward the north throughout the year without light pollution; other toward the glass curtain wall light pollution all the year round，winter solstice mainly in the south to east toward，the equinoxes heading south to northeast，the summer solstice in southern and Northern Dynasties outward all towards; light pollution duration was affected by impact towards the，winter solstice，equinox and solstice small. Light pollution affects the size of the region，the location of the change，the winter solstice，the spring and autumn and summer ease and stability. |
