Calculation of Effective Utilization Coefficient of Farmland Irrigation Water and Suggestions in Xinzhou
In order to analyze the current situation of farmland irrigation water,20 sample irrigation districts were selected in Xinzhou Municipality,and the effective utilization coefficient of farmland irrigation water in the whole municipality was reckoned based on the calculation of the sample irrigation districts.The results show that the effective utilization coefficient of farmland irrigation water in the city in 2021 and 2022 is 0.552 and 0.560,respectively,and the increase of 1.45％in 2022 is compared with that in 2021.This paper points out the existing problems,and gives some suggestions to improve the accuracy of calculation coefficient,which can provide reference for the implementation of irrigation project in Xinzhou.
