| Abstract: | According to the annualadministrative reports of 8 tributary of the Yellow River from Hekou to Longmen,the dataof round number sampling in 1985,detail survey in 1989,land use change survey in 1996 andtwo-stage sampling in 1997,and combining with acceptance check material of the first andthe second period national main harness area in the basin of Sanchuan river, thepreservation ratio of the water and soil conservation measures and its distribution havebeen analysed and determined. This work have made a good foundation for the calculation ofbenefits soil and water conservation measures on large area. |
