摘　　要：将生命周期思想引入农业用水增值研究,提出农业用水具有"开发—利用—废弃"的生命周期,各阶段既相互独立,又相互联系。探讨生命周期条件下农业用水增值理论,既要考虑各个阶段的增值,又要考虑其耦合增值。构建农业用水增值模型,研究生命周期条件下农业用水增值的模式与途径。为提高农业用水的利用率和利用效率,增加农业用水的产品和服务价值,实现农业用水增值奠定理论基础。The concept of the life cycle is introduced to the study of the added value of agricultural water use. A life cycle of exploitation-utilization-waste is proposed for agricultural water use. The stages of the cycle are both independent of and correlated with one another. Based on the life cycle, the added value of agricultural water use is discussed, with consideration of the added value in each stage and the coupled added value. A model of the added value of agricultural water use was constructed to study the added value mode and approach. This study provides a theoretical basis for the increase of the utilization rate and efficiency of agricultural water, the increment of the value of production and service, and promotion of added-value agricultural water use.
