Using the theory and method of system engineering, the mathematical model for the planning of backbone engineering dam system in controlling gullies in small watersheds was established in this paper. Through calculations, the combinations of the optmum dam construction in small watersheds and sequence of the implementation of the planning in years have been obtained. The method of obtaining solutions has the advantages of less calculation and short operation duration. The programming for the model is complete and universal software package of dam system planning suitable to the planningof backbone engineering dam system in controlling gullies of small watersheds of different landforms. The various optimum parameters are in coincidence with the requirements. The results from the application indicate that the mathematical model and its method of obtaining solution are right, and the programming is convenient and simple to use, thus creating a new way for the systematic and scientific planning of backbone engineering dam system in controlling gullies in small watersheds.
