本文通过对上海市水土流失现状及水土保持措施总结,提出上海市水土流失重点防治区划分的原则与指标。结合野外实地调查,利用USLE模型计算土壤流失量,为上海水土流失调查和重点防治区划分提供侵蚀强度重要参考依据,进而提出上海市水土流失重点预防区、重点治理区。 Based on the status quo of soil and water loss in Shanghai and the summary of soil and water conservation measures, this paper presents the principles and indicators for the division of key soil and water conservation areas in Shanghai. Combined with the field survey, the USLE model was used to calculate the amount of soil loss and provide an important reference for the investigation of soil and water loss in Shanghai and the division of key prevention and control areas. The key prevention areas and key control areas for soil erosion in Shanghai were also proposed.
