Abstract:

In view of China’s current serious water loss and soil erosion, the Unmanned Aerial Vehicle (UAV) oblique photography technique was introduced as an auxiliary monitoring method in land use field sampling in the Three Gorges Reservoir area of Yangtze River Basin to carry out remote sensing dynamic monitoring of soil and water conservation. High resolution remote sensing images obtained by satellite ZY-3 and GF-1 were selected as the main data source in soil and water conservation dynamic monitoring. Practice showed that China’s domestic satellite image quality has improved significantly by obviously reflecting the characteristics of land use types such as rice paddy field,slope farmland, orchard,tea garden, and forest land. Satellite ZY-3 and GF-1 can be effectively applied to the remote sensing dynamic monitoring of soil and water conservation. Moreover, as an auxiliary monitoring method, UAV technology has great potential in soil and water conservation and other related fields.
