摘要
作物水分生产函数是制定灌溉计划、进行灌溉效益分析和经济评价的有效工具。作物水分生产函数也是一种生产函数,根据经济学中生产函数的一般特性,分析了几种常用作物水分生产函数的结构形式、代表性及相关参数的经济学意义和可能的变化范围,为深入研究作物水分生产函数提供了经济学基础。
Water production function is a useful tool for the irrigation schedule making, the irrigation benefit analysis and the economical evaluation of irrigation projects. For water production function is a kind of production, so based on the general characteristics of production function, this paper analyzed the structure, representative, economic meaning and possible range for their parameters for the several static water production functions in common use. The analyzed water production functions included the gross-input liner and gross-input square water production functions, the stage-input additive and stage-input multiplicative water production functions. The results of this paper supplied with the economic basis for further studies of the water production functions.
