Abstract：Water erosion in twenty two soil and water conservation areas with basic water conservation function that were defined in the national regionalization of soil and water conservation was analyzed using the data obtained from the first national water resources census. More than 80% of the areas suffered from light or moderate water erosion and few are subjected to severe or extremely severe erosion, which is consistent with the nation-wide census result. Compared with the result of the second national remote sensing investigation of soil erosion, the water erosion got improvement on the whole: the total area of water erosion decreased by 3.75%, and the area of light and moderate erosion decreased markedly by over 20%. Nevertheless, the overall situation of water erosion in these areas is still serious. Regardless of the low percentage of the area with severe or extremely severe erosion, their absolute area increased to a large extent compared with the result of the second national remote sensing investigation, indicating the deterioration of water erosion in some areas.
