This resarch was doing in oder to investigation camparison different land use and slopes classes by yeild soil erosion (Rill and sheet erosion) in watershed kasillin Mazandaran. The kasillian watershed land use is specified to .1000 ha Dry farming .690 ha pasture , 3480 ha forest , 878 ha R.dry farming , 440 ha . Roads , 440 ha to happi table place and total area is about 6722 hectars. The statistical design is split plot including three major treatment of slopes classes (al=9% , a2 =25% , a3=45%) and four minor treat ments of land use (b1=pasture , b2=R.dry farming , b3= dry farming , b4=forest ). The measuring of soil erosion is taken monthly with plots (22.1 * 1.83 m) in different landuse excepting forestlanduse that it is doned with parecels area (102 m2). These plot and parcels is connected to storage tank with P.V.C pipe (1376-1381). The results of analysis data with soft ware SPSS is showed that amount yeild of soil erosion in different landuse is significant by statistically Duncan’s method( ل=0.01) and also different slopes classes is significant ( ل=0.05).The yeild of soil erosion (sheet Erosion and Rill Erosion)are in dry farming 0.75 ,R.dry farming 0.46 , pasture 0.29 and forest 0.11 ton per hectar in a year .
