Analysis on Calculation of Effective Utilization Coefficient of Irrigation Water in Zhaokou Irrigation District
In order to grasp the water use efficiency of agricultural water in Zhaoko Irrigation District,based on head-tail caculation method,the effective utilization coefficient of irrigation water utilization in Zhaoko Irrigation District for 2022 is determined.The results are compared with the other large-scale irrigation areas in Henan Province to determine its rationality.The results show that the head-tail caculation method can be well applied to the Zhaokou Irrigation Area.The effective utililzation coefficient of irrigation water utilization in the upstream reaches,middle reaches and entire irrigation area of Zhaoko Irrigation District reach 0.473,0.529,0.518.The effective utililzation coefficient of irrigation water utilization in the entire irrigation area is higher than the average level in Henan Provinc,which is in line with actual utilization of agricultural water,and can provide a theoretical basis for agricultural water management in the irrigation area.Finally,suggestions are proposed to solve the current problems of water management in the irrigation area.
