Abstract：Irrigation districts are crucial in safeguarding national food security and ensuring the stable supply of key agricultural products.Irrigation districts represent complex ecosystems and social systems,encompassing elements such as mountains,water,forests,farmland,lakes,grasslands,and sand.With the deepening of ecological civilization in the new era,issues related to ecology and the high-quality development of irrigation districts have attracted great attention.Summarizing the development of ecological-type irrigation districts in China over the past 30 years,it is proposed that a modern irrigation district should feature high yield and efficiency,ecological health,significant economic benefits,and harmonious social development.After reviewing the dynamic changes in the evaluation index system for ecological irrigation districts,considering new demands,new requirements,and new ideas,and considering construction standards,ecological friendliness,resource utilization,internal habitats of farmland,and coordination with surrounding ecosystems,this paper redefines the evaluation index system for modern ecological irrigation districts.To address the challenges related to the construction,operation,overall planning,standards,construction paradigms,scientific research,talent development,and management and evaluation,the paper proposes recommendations for the high-quality development of ecological irrigation districts,including updating and improving construction concepts and evaluation systems,scientifically formulating standards and plans,enhancing scientific research and talent development,improving planning and management mechanisms,and broadening investment and financing channels.
