Preliminary study on the method of soil erodibility value map-ping.

Bu Zhaohong(Institute of Soil Science,Academia Sini-ca, Nanjing 210008)and Li Quanying(Zhangjiakou Water andSoil Conservation Experimental Station,Hebei Province)  
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.
