Over the past two decades,the widespread application of remote sensing technology in the field of water conservancy has provided an effective means to acquire data over large areas with high frequency and resolution,while the capability of multi-spectral and multi-source data fusion has become increasingly prominent.Aiming to explore the prospects of remote sensing technology in the water conservancy domain,through a visual analysis of a knowledge graph constructed from water conservancy remote sensing literature within the Chinese national knowl-edge infrastructure database over the past two decades,we identified the focal areas and major trends.The findings reveal that key remote sens-ing techniques,water-related disaster prevention and mitigation,urbanization process analysis,ecological environment conservation,the construc-tion of intelligent water conservancy projects,and contributions to rural revitalization strategies have emerged as focal points in water conservan-cy remote sensing research.Furthermore,there is a discernible trend towards the utilization of advanced technologies,such as unmanned aerial vehicles and deep learning algorithms,to augment the interpretative and application capabilities of remote sensing imagery.This advancement is anticipated to provide robust support for the development of intelligent water conservancy initiatives.
