水利部将持续推进构建雨水情监测预报“三道防线”体系

Core Viewpoint - The Ministry of Water Resources is enhancing the flood forecasting system by establishing a "three-line defense" framework for rainwater monitoring and forecasting, aiming to extend flood prediction periods and improve forecasting accuracy [1] Group 1: Three-Line Defense System - The first line of defense involves meteorological satellites and rain radar systems that monitor weather systems and forecast potential floods before rainfall occurs [1] - The second line of defense consists of a rain gauge network that provides real-time monitoring of rainfall and analyzes runoff to forecast possible floods [1] - The third line of defense is a hydrological station network that monitors water levels and flow rates in rivers, lakes, and reservoirs, providing precise data support for flood defense [1] Group 2: Challenges and Future Plans - The Ministry acknowledges shortcomings in the current flood defense process, including insufficient density of hydrological stations in heavy rainfall areas and inadequate short-term forecasting capabilities [1] - Future plans include strengthening hydrological infrastructure in the "14th Five-Year Plan" and enhancing the integration and application of the "three-line defense" system to support scientific decision-making in flood defense [1]
