摘要
卫星遥感监测在弥补地面测点不足、全面感知水利工程态势变化及风险源识别方面具有优势。总结分析了光学遥感、雷达遥感监测技术特点及在水利工程中的应用现状,指出遥感影像分类识别、合成孔径雷达干涉形变测量技术在工程应用中尚存在准确度和精度不高、未与工程风险评估深度融合等问题;面向水利工程建设与运行管理的应用需求,从在建工程施工进度监督、在运工程形变精准监测及风险源识别预警等3个典型应用场景,探讨了水利工程卫星遥感监测技术的业务化应用路径,剖析了尚存在遥感监测定量化及时空分辨率不足、“天-空-地”多尺度协同监测不够的技术瓶颈,展望了水利工程遥感监测技术应用的发展方向。
Satellite remote sensing monitoring has advantages in compensating for insufficient ground measurements,comprehensively understanding behavior changes in water conservancy projects and identifying risk sources.This paper examines optical and radar remote sensing monitoring technologies,outlining their current application in water conservancy projects.It highlights challenges in image classification,recognition,InSAR deformation measurement,and their integration with risk assessment.In response to the application requirements for the construction progress and operation management of projects,the business application path of remote sensing monitoring for water conservancy projects is discussed from three typical application scenarios:progress supervision of projects under construction,precise deformation monitoring of operational projects,and risk identification and early warning.It analyzes technical bottlenecks,such as quantification,spatiotemporal resolution,and multi-scale collaborative monitoring.Finally,it outlines future trend in remote sensing monitoring technology for water conservancy projects.
