电表读数算水账——辽宁试点“以电折水”促节水增效

Core Viewpoint - The article discusses the implementation of the "electricity to water" monitoring system in Liaoning Province, aimed at improving water resource management for agricultural irrigation in a region facing severe water scarcity [1][4]. Group 1: Background and Context - Liaoning Province is one of the most water-scarce regions in China, with agricultural water usage accounting for over half of the total water consumption [1]. - Over 90% of existing agricultural irrigation wells lack water measurement facilities, making it challenging to manage water resources effectively [1]. Group 2: Implementation of the Monitoring System - The "electricity to water" system estimates water usage based on electricity consumption, allowing for a more efficient management of irrigation resources [1][4]. - The system involves selecting representative "sample wells" for monitoring, rather than installing measurement devices on every well, which would be financially burdensome [3][4]. - As of now, over 1,600 monitoring stations have been established in Liaoning Province to support the "electricity to water" initiative [4]. Group 3: Technological Features - The monitoring stations are equipped with devices that measure electrical parameters and water flow, enabling real-time data collection and analysis [3]. - The data collected can be used to create a comprehensive water usage map for the entire province, allowing for timely alerts on unusual water usage patterns [3]. Group 4: Benefits and Future Applications - The "electricity to water" system supports the precise management of irrigation water, particularly in water-scarce areas, promoting water conservation [4]. - It also provides data for optimizing irrigation system layouts and high-standard farmland construction, moving away from reliance on traditional experience-based methods [4].
