【摘要】 货币收获预估模型可以将林分生长因子与经济指标结合,不仅能够提供林分的产量和生长量,而且能提供相应货币收获量及动态变化规律,从而为森林经营者提供直观的林分收益状况。本文将货币收获预估模型分为单株货币收获模型、直径分布货币收获模型和全林分模型货币收获模型。在此基础上,根据所收集的材料,建立了以生长收获模型为基础的单株货币收获预估模型、直径分布货币收获预估模型和全林分模型货币收获预估模型。其次,以货币收获表为基础建立了密度效应模型,分析了密度变化对单株货币收获的影响。随后分析了各项经济指标变化对单株货币收获表和直径分布货币收获表的影响。最后讨论了货币收获预估模型在柳杉人工林最优密度控制、经济成熟和森林资源资产评估中的应用。

【Abstract】 The monetary yield estimate model can connected stand growing elements with the indexes of economic. It can offer the stand’s output , corresponding monetary yield and dynamics change rule. The monetary yieldestimate model is divided into three kinds------individual tree monetary yield model,diameter distribution monetary yield model and whole-monetary yield model. These three kinds of monetary yield models are established by the gathering information and their bases are growth and yield models. Next ,density effect model which is based on monetary yield is established and how the density change influences individual tree’s monetary yield is discussed .Then ,the result of how each the indexes of economic change influence individual tree monetary yield model and size-class distribution monetary yield model. Finally, the application of monetary yield model in the optimized control on Chinese Fir plantation density, the economic maturity and the assessment of forest resource assets is discussed in this paper.
