Abstract

Abstract: The paper takes Kaizhou District of Chongqing as the research object, and 6 sample irrigation districts were selected as a representative. And calculate the effective utilization coefficient of irrigation water in the sample point irrigation area of Kaizhou District by using the head-tail method. The effective utilization coefficient of irrigation water in the whole district is based on that of in the sample irrigation area. Through statistical analysis, it is concluded that the effective utilization coefficient of irrigation water in Kaizhou District in 2019 is 0.4994.The research results can effectively support the assessment of the most stringent water resources management system in Kaizhou District, and can also provide a certain reference for the development of agricultural efficient water-saving irrigation.
