垂直面绿化植物叶片遮阳系数的确定

在建筑物垂直面绿化研究中，考虑植物的叶片遮阳系数与农，林业中常用到的顺面积指数LAI不同，而是一个由叶片倾角，太阳光线入射角与叶面积指数决定的函数，在文中首次定义该影响系数为垂直面积植物叶片遮阳系数，推导求出该系数的函数定义关系式，测定了常用的攀缘类植物爬山虎的叶面积指数。

Determination of Shelter Coefficient of Planting Vertical

When research on the planting vertical wall of buildings, the leaf shelter coefficient of planting vertical wall(SCPVW)is not same as the leaf area index(LAI)of agriculture and foestry. SCPVW is a function which depends on the average degree of angle formed by leaves and the horizontal and the angle of sunlight entrancing on the surface of the vertical wall. This coefficient is firstly defined as SCPVW in this paper. The SCPVW function has been worked out for the first time. And the LAI of the climbing plants,Parthenocissus tricuspidata (Sieb. Et Zucc. )Planch. Usually used for planting of the building,was surveyed and determined in the paper.
