与时俱进的水利遥感

Advance of hydrographic remote sensing with time

本文回顾了随着水利事业发展与时俱进的水利遥感技术应用研究及其实际应用发展的历程。阐述了水利遥感在涉及防灾减灾的洪涝灾害、旱情和涉水地质灾害监测评估、洪水预报预警;涉及水资源监测保护的卫星遥感降水量预报、土壤含水量与蒸散发量遥感估算、地表水体监测、地下水监测、水环境监测和地表水体保护;涉及生态保护的生态环境监测、水土保持和灌溉面积调查、河道与河口变化监测和治理等方面发挥的重大作用。分析了水利遥感应用研究的发展方向,认为水利遥感的发展必须以应用需求为驱动,以实现为业务工作提供服务为发展目标,加强遥感技术在水利业务工作中的推广应用是水利遥感发展的必由之路。

This paper reviews the development history of applied research and application of hydrographic remote sensing with the development of water conservancy,describes the important role played by remote sensing technology in the fields of monitoring and assessment for flood and waterlogging,drought and geographic disaster related to water,flood forecasting,precipitation prediction,soil moisture and evapotranspiration estimation,monitoring of surface water body and ground water storage variation,water environmental monitoring,surface water and ecosystem protection,soil erosion estimation,investigation of irrigable landarea,variation monitoring of river course and river delta,especially the role played in professional work of water sector. It analyses the development orientation for applied research of hydrographic remote sensing. It is pointed out that the application requirement must be the driver for the development of hydrographic remote sensing,and the target is the realization of providing service to professional work. The popularization and application is the only way for the development of hydrographic remote sensing.
