Abstract：As the global water shortage problem becomes increasingly prominent,water conservation has become an urgent and important task.Precision irrigation technology has attracted widespread attention as an effective means of water conservation.The water-saving benefits based on precision irrigation technology are evaluated and optimized.The definition,principles,classification and application fields of precision irrigation technology are reviewed,and its advantages in water saving are discussed.This paper introduces the methods of water-saving benefit evaluation,including common indicators and evaluation methods,and analyzes the relationship between evaluation indicators and actual scenarios.Through experimental design and data collection,the application effects of precision irrigation technology on different crops were evaluated,and the water-saving benefit evaluation results were statistically analyzed.Optimization strategies are proposed,including optimization directions and methods for precision irrigation technology,as well as comprehensive optimization strategies that consider economic,environmental and social factors.Typical cases were selected for analysis,the impact of different factors on water-saving benefits was discussed,and the limitations and challenges of precision irrigation technology in practical applications were discussed.An economic analysis of water-saving benefit evaluation and optimization was conducted,an economic model was established,the relationship between water-saving benefits and economic benefits was analyzed,and the balance between economic costs and environmental benefits was considered.This article aims to provide theoretical guidance and decision support for the application and optimization of precision irrigation technology to achieve sustainable water resource utilization and agricultural production.
