水利遥感卫星应用体系构建与展望OA

Since the 14th Five-Year Plan period,the Ministry of Water Resources vigorously advances the construction of the digital twin water conservancy system by fully leveraging the strategic,foundational,and supporting roles of remote sensing satellite applications in systematically planning and advancing the system and promoting the deep integration of satellite remote sensing technology with water conservancy operations.At present,water conservancy remote sensing satellite applications have enabled the aggregation of multi-source imagery,established a streamlined image-processing system,and provided support for core water conservancy operations.For the two types of operational applications,namely water conservancy element monitoring and water conservancy governance and management monitoring,deficiencies remain in coverage breadth,monitoring elements,monitoring accuracy,and data timeliness.On this basis,the overall layout of the water conservancy remote sensing satellite application system is proposed.The system construction plan is elaborated in detail from four dimensions:satellite resources,data resources,business applications,and technological innovation and standards.Finally,key tasks are identified,including effectively expanding satellite resources,establishing a data aggregation platform,and deepening business applications.These initiatives aim to systematically enhance the digital and intelligent capabilities and overall level of water conservancy governance and management,thus providing solid support for safeguarding national water security.
