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.
