[Objective] The application of unmanned aerial vehicle(UAV) low altitude remote sensing technology in soil and water conservation monitoring is explored

which lays the foundation for the application of this technology to the comprehensive treatment of small watershed

supervision and management of soil and water conservation

construction supervision and acceptance of soil and water conservation.[Methods] Taking the Changlongshan pumped-water-storage power station project of Zhejiang Province as the study case

in reference to the regulation of soil and water conservation monitoring for construction projects(trial)

we carried out the application of UAV remote sensing technology to the monitoring case analysis of soil and water conservation

including background data analysis

remote sensing data acquisition

monitoring information extraction and application.[Results] Low-altitude remote sensing technology of UAV

combined with traditional positioning observation method

can complete the monitoring work precisely and quantitatively. The works included the monitoring of land-use types

disturbed range and soil loss

cuting and filling volume

hidden dangers and harm of soil erosion

measures for soil and water conservation

etc.[Conclusion] Application of low altitude UAV remote sensing technology to monitoring of soil and water conservation has high reliability and practicability

and it can meet the requirements issued in the regulation of soil and water conservation monitoring for construction projects(trial). The more important things are that it can level up the technical skills if UAV remote sensing technology as applied in real work of soil and water conservation monitoring

and can give strong technical support for the prevention of soil and water loss in construction projects as well.
