| 摘 要： | 运用方差分析方法研究了河套灌区1990-2000年单位面积灌溉用水量变化的影响因素.结果表明:渠道衬砌、渠系配套建设等工程节水措施和用水管理措施对减少灌区用水量产生显著影响,而种植结构调整因素和降雨对灌区用水量产生的影响并不显著.在将来的节水改造中,应继续加强种植结构调整以增强节水效果.本研究所建立的模型拟合优度好,能准确地解释和评价灌区用水量的影响因素.

| Abstract: | Based on the analysis of variance,the influence factors of irrigation water quantity per hectare of farmland in Hetao irrigation district from 1990 to 2000 are analyzed in this paper.The result shows that some water-saving measures,such as canal lining and relative canal system construction,and some water management measures have remarkable influence on the decrease of irrigation water quantity.While the influences of cultivation structure adjustment and rainfall are insignificant.The cultivation structure ... |
