为健全水资源计量监测体系，破解海量农业灌溉机井取水计量难的困境，河北省积极探索落实与水资源刚性约束制度相匹配的适用于农灌机井计量监测的建设方案和配套管控模式。从总体思路、存在的问题、典型建设模式、技术手段创新四个方面，总结分析了河北的实践探索。在顶层设计方面，完成农业取水计量体系建设中长期建设目标和重点任务制定，明确“近期全面实现‘以电折水’，逐步扩大计量监测范围”的农灌机井计量监测体系整体建设思路；在分析农灌机井计量监测体系存在的问题的基础上，提出“以电折水”、计量服务、水电联计、以电控水四种农灌机井计量监测长效建管典型模式；研发一体式泵管型超声波流量计、农灌机井水电融合终端、取水计量监测系统平台等一系列适用于农灌机井计量监测的创新技术，基本形成一套可推广、可应用的农灌机井计量管控体系长效建管机制建设方案。

To establish a comprehensive water resource metering and monitoring system and overcome the challenges of measuring water usage across numerous agricultural irrigation wells, Hebei Province has actively explored and implemented construction plans and management models tailored to the metering and monitoring of agricultural irrigation wells, aligned with rigid water resource constraints. From three perspectives of top-level design, typical construction models, and technological innovation, this study summarizes Hebei's practical exploration efforts. In terms of top-level design, long-term construction goals and key tasks for an agricultural water metering system were developed, focusing on the overall approach of “achieving ‘water metering by electricity' in the short term and gradually expanding the monitoring scope”. Four typical longterm construction and management models were proposed, namely, “water metering by electricity”, metering services, combined electricity and water metering, and water control by electricity. Technological innovations include the development of an integrated pump-pipe ultrasonic flowmeter, a water-electricity integration terminal for agricultural irrigation wells, and a water intake metering and monitoring platform. These efforts have resulted in a replicable and applicable construction plan for a sustainable agricultural irrigation well metering and control system, establishing a long-term management mechanism.
