Based on the distribution of hydrological stations and zoning of types of soil erosion, the Loess Plateau(310 × 103km2) is divided into 292 erosion units. And taking the erosion modulus ＞ 5000t/km2 as a criterion, the empha-sis control area (149 × 103km2) of the Loess Plateau is demarked, and is divided into 10 control regions. The control-lable area and the location of control measures are conformed. Level terraces are mainly collocated on the 3°- 15°slopes, woodland and grassland are collocated on the ＞ 15° slopes, and the proportion of woodland to grassland is 8:2 inthe forest belt, 5:5 in the forest steppe belt, and 2:8 in the steppe belt. The 9000 combinations of soil-water conserva-tion measures in different rainfall conditions are obtained by the permutation and combination method, according to the 9rainfall frequencies and the controllable areas of level terrace, woodland and grassland at 10% of control progress rate.The quality standards of level terrace, woodland and grassland are ascertained. The evaluation indexes of soil-water conserva-tion benefits of level terrace, woodland and grassland are established respectively in the condition that rainfall index ishigher than that of erosive index of sloping field. Based on the results above, the sediment reducing benefit and soil ero-sion modulus in the different rainfall conditions and control degrees are analyzed, which could provide a decision-makingbasis for soil-water loss control on the Loess Plateau.
