基于椭球函数的棉花叶倾角分布动态模拟（Dynamic Simulation of Leaf Inclination Angle Distribution Based on Ellipsoidal Function）
棉花 叶倾角分布 椭球函数 动态模拟
2009/5/22
根据试验资料，在系统分析棉花冠层叶倾角时空分布规律的基础上，将整个生育期分为4个生长阶段，并利用高斯五点距离法将冠层分为5层，用椭球分布函数模拟不同生育阶段、不同高度层上的叶倾角分布密度。模型能较全面地反映整个生育期冠层不同高度上的叶倾角分布情况，且方便用于分层的光合作用模型。利用不同播期的试验资料对模型进行验证，叶倾角频率分布的模拟结果与1∶1直线之间的决定系数R2和均方根误差（RMSE）分别为...
