Abstract In order to study the current situation of soil erosion and conservation measures in Shanghai,based on the soil and water conservation census result of the China Census for Water, and combined with the basic situation of Shanghai, the paper analyzed the present situation of hydraulic erosion and soil and water conservation measures of the city. The result showed that the soil and water loss area covered more than 200 km2, and mainly occurred at the riparian zone. Furthermore, the soil and water loss caused by construction project is also serious. The soil and water conservation measures in city center is relative perfect, but that in suburb channels especially slope protection are not effective, which almost presented a state of nature, subsequently easy to loss soil and water. Therefore, the riparian restoration and treatment are key task for soil and water conservation in Shanghai. At the same time, in order to prevent artificial soil and water loss, we should strengthen supervision of construction project and monitoring of soil and water conservation.
