leaf-area-index lai

基本解释

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。
This new metric, the green plot ratio (GPR), is based on a common biological parameter called the leaf area index (LAI), which is defined as the single-side leaf area per unit ground area.
这个新指标——绿色容积率（GPR）是以一个通常被称作叶面积指数（LAI）的生物参数作为基础，该参数被定义为每单位地块面积上的单面叶面积总和。
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；
