充分考虑坡地人工林冠层结构特征和叶面积空间分布的异质性 ,分别相邻树冠遮荫和目的树冠遮荫对树冠内辐射场的影响 ,建立的人工林冠层辐射场模型 ,可模拟树冠内任意点 ,在一年内任一时刻内的辐射及其直接和散射分量 ,以及以 1h为步长的日总辐射等 ,为人工林可持续经营和冠层光合生产力模拟奠定基础 Considering the heterogeneity of the canopy structure and the spatial distribution of leaf area in the sloping canopy, the influences of shade of the adjacent canopies and shading of the canopy on the radiation field in the canopy were also considered. The canopy canopy model was established to simulate the canopy inside the canopy At any point, the radiation and its direct and scattered components at any one time of the year, and the total solar radiation in 1-h increments provide the basis for sustainable management and canopy productivity simulation of plantations.
