The project,“Research into soil erosion processes and control in the major water erosion regions of China”,aims to address the urgent needs of China′s national strategy and scientific developments of soil and water conservation.Taking the 4water erosion regions of northeast black soil,northwest loess,South China red soil and southwest purple soil as the main study areas,the research has concentrated on soil erosion process,modeling and control mechanisms.After more than 4years research,the following have been achieved:revealing soil erosion development processes and spatial patterns,factors and mechanisms of different types at different scales;developing a Chinese multi-scale soil erosion prediction modeling system;developing methods of evaluation for impacts of soil erosion/conservation on environment,and integrating soil erosion control models to fit into the natural ecology and social economy in different regions.All of these achievements have enriched and developed soil and water conservation science,and provide a theoretical basis for the national soil and water conservation strategy and planning in China.
