灌溉水有效利用系数是评价灌溉用水效率的有效指标。根据黑龙江省近几年不同灌区实际灌溉用水有效利用系数测算资料,建立GM(1,1)预测模型,预测结果与地实际情况比较吻合。
灌溉水有效利用繫數是評價灌溉用水效率的有效指標。根據黑龍江省近幾年不同灌區實際灌溉用水有效利用繫數測算資料,建立GM(1,1)預測模型,預測結果與地實際情況比較吻閤。
관개수유효이용계수시평개관개용수효솔적유효지표。근거흑룡강성근궤년불동관구실제관개용수유효이용계수측산자료,건립GM(1,1)예측모형,예측결과여지실제정황비교문합。
It is the efficiency index to estimate for the irrigation water efficiency with the factor of ef-fective utilization irrigation wate.Accorded to the effective utilization factor of irrigation water of dif-ferent irrigated areaes in Heilongjiang Province , recent years , established GM(1,1) model for cal-culation,this is in well agreement with experimental results obtained lately.
