Abstract：Loess Plateau is a region that has the most severe soil erosion problems in China and in the world. Although prevention has been performed continuously in the recent 50 years, the efficiency was limited and the improvement of eco-environment was slow. The study indicates that the strategy to improve the efficiency of control should be as follows, that the eco-environmental constructions should follow scientific principles; the concepts against natural regularities should be abandoned; the target of prevention should be rational and practicable; high yield farmland can be established by building dams; afforestation and vegetation construction should be designed according to water conditions. An approach of regulating runoffs and integrated management in small watersheds should be adopted. It is proposed to establish administrative agents, distribut the engineering projects, and recover forests and grasslands.
