三义寨灌区灌溉水有效利用系数影响因素分析
Analysis of Influencing Factors of Effective Utilization Coefficient of Irrigated Water of Sanyizhai Irrigation Area
摘要
Abstract
In order to solve the low effective utilization coefficient of irrigated water and based on multivariate linear regression analysis, it studied the main factors influencing the effective utilization coefficient of irrigated water. The results show that in the selected eight impact factors, the order of the effective utilization coefficient of irrigated water from high to low is the rate of supporting facilities in good conditions>the rate of channel lining > investment of water saving engineering > actual irrigation area > the length of channel> actual diversion > the amount of rainfall > groundwater modulus. Then, combined with the actual condition of Sanyizhai irrigation area, using the results of the regression analysis, the paper puts forward to improve the existing irrigation engineering and irrigation technique, formulate reasonable irriga⁃tion management system and continue to strengthen investment of water saving engineering as the potential strategy to solve the problem of the low-effective utilization coefficient of irrigated water.关键词
