卫星遥感水资源调查监测应用现状及展望

Application status and prospect on water resources investigation and monitoring by satellite remote sensing

针对传统水资源调查监测手段效率低、成本高、难度大等局限性,开展基于卫星遥感水资源的调查监测具有重要的意义。同时,对于守住水资源利用红线、守护绿水青山、建设生态文明均具有重要的作用。本文梳理了相关研究成果,阐述了卫星遥感水资源调查监测的具体内容,着重介绍了卫星遥感在水体位置、面积、水位、储水量、径流量、水质等方面的应用现状。最后,分析了当前应用中存在的问题并对后续需要重点开展的工作进行了展望。

Aiming at the limitations of traditional water resources survey and monitoring methods, such as low efficiency, high cost and difficulty, it is of great significance to carry out survey and monitoring of water resources based on satellite remote sensing.Meantime, it plays an important role in maintaining the red line of water resources utilization, guarding green mountains and clear water and building ecological civilization.This paper combs relevant research results and introduces the specific content of satellite remote sensing in water resources investigation and monitoring, and focuses on the application status of satellite remote sensing in water location, area, water level, water storage, runoff, water quality, etc. Finally, the existing problems in the current application are analyzed and the future work is prospected.
