Leaf-canopy的意思|示意

Canopy is measured according to leaf-area-index (LAI) relative to wall area; for each unit of LAI, sunlight decreases by about half.

雨棚是根据相对于墙体面积的叶面积指数(LAI)来测量的；每单位LAI，日照减少约一半。

The Leaf Angle Distribution (LAD) and Leaf Area Index (LAI) are important descriptors of the vegetation canopy.

叶面倾角分布（LAD）和叶面积指数（LAI）是植被冠层结构的重要参量。

The result showed that the light distribution in the canopy were obviously affected by the leaf area index (LAI), the structure of canopy, solar radiation and its apparent movement, etc.

结果表明：梨树叶幕光能分布状况直接受叶面积系数、树冠结构、太阳位置及光强的影响。

Leaf area index (LAI) is a crucial parameter of vegetation canopy structure and controls a number of biophysical processes of vegetation.

叶面积指数(LAI)是植被冠层结构的一个重要参数，它的改变标志着植被发生了生物物理变化。

Despite the blanketed look of rain forests from above, canopy trees actually rarely touch, possibly to minimize the spread of disease and leaf-eating bugs.

尽管被雨雾覆盖从上面仍可观看雨林，天蓬树实际上难得触及，也许将树的疾病蔓延减到最小和消除吃叶的虫害。

Interplanting leaf area index, the daily changes of light transmittance and light intensity in the middle part of the canopy are observed with the LAI-2000 type and photometer.

采用LAI-2000冠层仪和照度计进行行间叶面积指数、株间透光率及树冠中部光照强度日变化进行测定；
