Abstract The first national survey for water and meanwhile for soil erosion was conducted during the period of 2010 -2012. The adopted survey methodology, acquired data, organizing mode were harmonized unprecedently in this national soil erosion survey. Through this survey, the soil erosion area,distribution and intensity were clarified at the national scale. Furthermore, the quantity, distribution area of the eroded gullies in the northwest Loess Plateau and northeast black earth regions were also quantified for the first time, as well as the implemented type, quantity and distribution of the respective prevention measures. These survey results objectively reflected the national status of soil and water losses and the effects of long term protecting efforts, moreover, provided a scientific basis for decision—making for national ecological construction, and soil and water conservation as well. It is recommended that the next steps would be to strengthen the soil and water conservation course, especially focusing on specific regions, to advance the ecological restoration at larger scale, to intensify the comprehensive treatment of sloping croplands and eroding gullies, to initiate ecologically clean watershed projects and to reinforce the information construction of soil and water conservation.
