Abstract：Soil and water conservation forest system is one of the important parts of protection forestry system. It plays an important role in improving ecological environment and controlling soil erosion and water losses. The history and the present situation of the research system of water and soil conservation forest system are reviewed, and the main achievements and problems are pointed out briefly. The researches of the former Soviet Union, Austria and China have obtained more achievements, and have played a leading role in the world. The forest-technical system of Austria has been used and popularized in many countries. The research results of mechanism of soil and water conservation forest have become the theoretical basis in the researches of soil and water conservation forest in the world. The theories of eco-forestry and soil and water conservation forest for erosion control are important contributions to the world's soil and water conservation system. The main problems of small watershed conservation forest system at present are that researching scales, unstabilitive stands, lack of theory research and unreasonable space configurations. To solve these problems reasonable will be the researching direction of forest for zerosion control in the future.
