The properties of soil and water losses from slope field in red soil in six farm ing systems were conducted in Lanxi soil and water conservation supervision stat ion, Zhejiang province in 2000.The results showed that: Compared with convention al farming system (treatment 5,straight farming system), other farming system re duced water and soil losses significantly .Fallow farming system dec reased runo ff by 42.8% and sediment by (85.02)%,other farming system, contour dam farming sys tem, grass strip farming system, contour ditch farming system ,contou r farming system decreased runoff by 70.20%,by 32.33%,by 45.60%,by 56.33% and sediment by 95.04%,by 45.88%,by 63%,by 87.7% respectively .Contour dam farming system,cont our farming system and fallow farming system were better than grass strip farmin g system and contour ditch farming system on control losses of soil and water .E xcept contour dam farming system and contour farming system, the loss of bed loa d was exceed to loss of suspend material .Runoff and sediment concentrated in Ma y to August accounting for above 80%,the factors that impacted the losses of so il and water were precipitation,rainfall erosion index,plant coverage.
