| 摘 要： | 运用水量平衡法原理,以贵州省连续5年观测资料为基础,精确测定了贵州省＂十一五＂期间水稻灌区灌溉水利用系数。并以此为基础,分析了贵州省灌溉水利用系数随节水改造投入以及灌区管理水平影响产生的变化规律。测算结果表明,贵州省灌溉水利用系数随节水改造力度加大,有逐年上升趋势,说明该省节水改造成效显著。

| Abstract: | Water equilibrium method principle was used and based on five-year observational data in Guizhou Province,productivity coefficients of irrigation water in rice irrigated areas during Eleventh Five-Year period in Guizhou were determined precisely.Based on this,the changing regularity of productivity coefficients of irrigation water with the input of water saving and reforming as well as management standards of irrigated areas were analyzed.The calculated results showed that there were rising trend yearly wit... |
