A computer system, which was suitable for the acceptance of comprehensive control and benefits evaluation benefits of experimental watershed of soil and water conservation, was designed by modern information technology. It could make data processing and evaluation scientific and normal, and meantime create the entity base of watershed management. All these can provide comprehensive control of watershed in different regions with patterns. This management information system of experimental watershed can combine the entity base with acceptance and evaluation of experimental watershed, and directly provide the results of comprehensive rehabilitation and its benefits.
