【摘要】：推行节水灌溉技术的节水效果可能被产出增长带来的新增用水抵消,甚至出现用水有增无减的现象,表现为灌溉用水的反弹效应。目前有关灌溉技术节水效果的研究已有丰富成果,但关于灌溉用水反弹效应的研究还缺乏系统梳理。从灌溉用水反弹效应概念内涵、灌溉用水特性与节水的尺度效应、灌溉用水反弹机制以及反弹程度4个角度综述相关文献。灌溉过程中的水量转化、水分消耗及用水效率评价非常复杂,对灌溉用水反弹的研究还需进一步深入。未来研究的重点领域包括:(1)灌溉用水反弹的定义,如区分水文反弹和经济反弹,区分用水反弹和耗水反弹,区分一般反弹效应和回火效应(大于100%的反弹);(2)灌溉用水反弹的作用机理和控制路径;(3)设计合理的方法实证计算反弹效应。
[Abstract]:The water-saving effect of water-saving irrigation technology may be offset by the increase of output, even the phenomenon of unabated increase of water use, which is manifested by the rebound effect of irrigation water. At present, the research on the water saving effect of irrigation technology has been fruitful, but the research on the rebound effect of irrigation water is still lack of systematic combing. The related literatures were reviewed from four aspects: the concept of rebound effect of irrigation water, the characteristics of irrigation water use and the scale effect of water saving, the mechanism of rebound of irrigation water use and the degree of rebound. The evaluation of water conversion, water consumption and water use efficiency in irrigation process is very complicated. Areas of focus for future research include: (1) definitions of irrigation water rebounding, such as distinguishing between hydrological and economic bounces, water rebounds and water consumption rebounds, The mechanism and control path of general rebound effect and tempering effect (more than 100% rebound); (2) are distinguished. (3) reasonable methods are designed to calculate the rebound effect.
