| 摘 要： | 比较、分析了农业研究中提出的叶面积指数LAI与用于建筑节能领域的垂直面绿化植物叶片遮阳系数SCPVW两个概念的异同和各自的应用范围。指出城市绿化采用水平或垂直绿化方式时，由于下垫面差异，植物叶片的遮阳系数应当分别采用LAI和SCPVW进行计算。

| Abstract: | The similarities and differences between the leaf area index (LAI) and the shelter coefficient of planting vertical wall(SCPVW) is discussed. LAI was typically used in agriculture and SCPVW is usually used in energy saving technique in architecture. There exists much difference when analysing the reducing rate of sunlight between the horizontal and vertical planting.It is concluded that LAI can be used as the shelter coefficient when designing horizontal planting plane and SCPVW can be used as the shelter coefficient when analyze vertical planting wall . |

| Keywords: | shelter coefficient leaf area index average degree of angle formed by leaves and wall |
