Abstract

The modernization of irrigation districts is of great significance for improving irrigation efficiency and ensuring food security, while ecological flow is a fundamental prerequisite for maintaining the stability of surrounding ecosystems and ensuring the sustainable utilization of water resources. However, in some modernization projects, excessive emphasis has been placed on irrigation while ecological considerations have been neglected, resulting in insufficient ecological flows and frequent ecological problems. This paper expounds the concepts of irrigation district modernization and ecological flow, and clarifies their interrelationship. It further analyzes the engineering, management, and climatic–environmental factors affecting ecological flows, and constructs an ecological flow guarantee mechanism by defining objectives, accounting methods, and multi- dimensional safeguard measures. The results indicate that a sound guarantee mechanism can achieve synergy between irrigation benefits and ecological benefits, providing practical reference for ecological flow protection in irrigation districts.
