摘要
通过对落叶松人工林枝叶空间分布的研究 ,给出落叶人工林叶面积空间分布函数。综合多因子的影响 ,确定冠影响函数形式 ,从而确立由冠影响下的资源等级的函数形式。综合邻近树冠的共同影响 ,给出落叶松林地的资源等级水平分布情况。
Through studying the space distribution of branches and leaves of larch plantation, the distribution function of leaves areas was given, and crown influencing function was founded by synthesizing the effects of multi-factors, thereby the function of resource degree influenced by tree crown was put forward. According to the total effects of neighboring crown, the horizontal distribution of resource degree for larch was expounded.
