【摘要】 从森林生态效益计量角度出发．在分析生态效益作用的机理基础上．给出了森林生态效益的定义。明确指出．森林资源是森林生态效益的载体．二者之间是一种松散的相关关系、即第二类的相关关系。由此产生森林生态效益的自变量所特有的区域自变量集和林分自变量集。在界定森林涵养水源等10种生态效益的概念、性质和它们的相关关系基础上．确定它们独立的自变量集和标准化因变量集．并构造它们的整体扩散模型、从而实现对我国林业生态工程的10种森林生态效益的总体初步估计。更多还原

【Abstract】 From the view of measurement of forest ecological benefits. based on the analysis of their actionmechanism, forest ecological benefits were defined. It definitely pointed out that the forest resources wasthe carrier of forest ecological benefits. and they had the friable relationships which was called thesecond relation. It generated the special regional independent variable set and stand independent variableset. Based on the concept, property and relationship of 10 forest ecological benefits. their irrelativeindependent variable set and standard dependent variable set were determined. and the whole spreadingmodels were set up. So the gross estimation of forest ecological benefits was made.更多还原
