水土保持遥感应用成效与展望OA

Satellite remote sensing has been widely applied in the field of soil and water conservation for its comprehensive,accurate,and rapid characteristics.In recent years,the Ministry of Water Resources has utilized multi-source remote sensing data to conduct dynamic monitoring of soil and water loss,remote sensing supervision of soil and water conservation,and investigations of erosion gullies in the Northeast black soil region.These efforts have provided a comprehensive and systematic understanding of the annual soil and water loss situation and its dynamic changes across various administrative regions in China.Additionally,the Ministry has identified weak links in human-induced soil and water loss supervision and addressed numerous violations of laws and regulations.The investigations have also covered the quantity,distribution,and changes in the erosion gullies of the Northeast black soil region.With the advancement of remote sensing technology,new techniques such as hyperspectral remote sensing,LiDAR,and stereoscopic surveying satellites show promising applications in soil and water conservation monitoring.The innovative application and future development prospects of remote sensing technology in this field will definitely foster new quality productive forces in soil and water conservation.
