Based on explaining some concepts of urban soil erosion and soil and water conservation and the necessity of developing soil and water conservation in urbanized areas,the characteristics of soil erosion occurred in urbanized areas,such as being mainly humanaffected,complexity of erosion patterns,concealment of erosive intensity and multifold sources of eroded materials etc.,have beed further discussed.There are some relative characteristics of soil and water conservation in urbanized areas also being studied,which includes special purposes and demands,key point of controlling erosion caused by human activities,involving many different aspects and regional structure of urban area,the basis of control measures for soil and water conservation etc.Furthermore,types and contents of soil and water conservation in urbanized areas have been analysed.
