The observation of soil and water loss in Luoyugou watershed began in 1985. It is one of the longest built and best continuous observation basins in China. In 2018, all the observation network systems of Luoyugou small watershed were included in the national comprehensive observation station of national soil erosion dynamic monitoring project. This data set includes the basin boundary information and the location information of water and soil conservation observation facilities such as watershed control station, rainfall station, meteorological Park, vegetation observation point, runoff plot, and the distribution of typical soil and water conservation engineering measures such as warping dam. </p>\n <p>Remote sensing image interpretation adopts human-computer interaction interpretation method, and data processing is carried out in accordance with the steps of establishing interpretation flags, indoor human-computer interaction interpretation, field verification, revision and digital map generation.</p>\n
