中文摘要：
针对农田灌溉水有效利用的问题，以安徽省为例，运用灰色预测和等维灰色递补的方法，建立了农田灌溉水有效利用系数模型，使用MATLAB和EXCEL等软件求解，综合分析了安徽省农田灌溉水利用的现状．利用2005--2014年安徽省每年的水资源相关数据，预测出2015--2020年安徽省农田灌溉水有效利用系数．结果表明，2015--2020年安徽省农田灌溉水有效利用系数逐年增大，未来农田灌溉水的利用效率越来越高，有利于形成农业节水的新格局．
英文摘要：
Aiming at the problem of efficient utilization of irrigation water in farmland, taking Anhui Province as an example, the model of effective utilization coefficient of irrigation water in farmland is established by gray prediction and equal dimension grey filling method. Using MATLAB and EXCEL software, the present situation of farmland irrigation and water conservancy in Anhui Province is analyzed. Based on the data of annual water resources in Anhui Province from 2005 to 2014, the effective utilization coefficient of irrigation water in Anhui Province from 2015 to 2020 is forecast. The results shows that the effective utilization coefficient of irrigation water in Anhui Province is increasing year by year in 2015--2020, and the utilization efficiency of irrigation water in the future is getting higher and higher, which is conducive to the formation of new pattern of agricuhural water saving.
