我国灌溉用水效率提升潜力与实现路径
Potential for improving irrigation water use efficiency in China and realization path
摘要
Abstract
The effective utilization coefficient of irrigation water is a key indicator of irrigation water use efficiency and serves as an important assessment metric under China's strictest water resources management system.Monitoring data indicate that,with increased national investment in water-saving renovation and improved management in irrigation districts,the effective utilization coefficient has improved to varying degrees across large,medium,small,and pure well irrigation districts,but there is still potential for improvement compared to water-saving irrigation standards.Influenced by factors such as water conveyance infrastructure,field irrigation techniques,and irrigation district management,as well as inherent attributes like district scale and natural conditions,the effective utilization coefficient varies across districts and regions,and its improving potential should be analyzed systematically and evaluated scientifically,taking into account the requirements of water conservation,high efficiency,economic rationality and ecological health.Improving the effective utilization coefficient of irrigation water is a systematic endeavor involving multiple sectors,including water resources and agriculture,necessitating integrated considering,systematic approach,coordinated efforts,and accelerated implementation.关键词
