The light distribution within the canopy is subject to the leaf area index and the extinction coefficient.
光在冠层内的分布，受叶面积指数和叶片消光系数支配。
In the model, the leaf area index (LAI), crop coefficients, and root penetration and distribution were simulated for the winter wheat and summer corn double cropping system.
模型对冬小麦—夏玉米轮作体系作物叶面积指数、作物系数、根系生长与分布进行了模拟。
This is closely related to the distribution of leaf area of population.
这与种群的叶面积分布特征密切相关。
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。
