Abstract: The mapping method of soil erodibility(K)value using soil survey maps and the physico-chemical proper-ties of soil profiles was described.The method involves soilprofile K value determination by looking up graph and table,the combination and separation of map unit, and mapping pro-gram. First regional wide K value map compiled based on themethod.The accuracy of looking up graph and table method is85.4%,used for monitoring annual soil loss,the accuracy ofK value in map unit is 86.0%compared with the determinedvalue of runoff plot. 

Key words: soil erodibility, looking up graph and tablemethod, soil loss monitoring
