%X In this paper .the concepts of entropy ,flux and force in the drainage-geomorphic system have been introduced,and an equation for the entropy production and super-entropy production has al-so been conducted,According to this concept,dynamic mechanism in the drainge-geomorphic sys-tem is analysed,and an evolutional model for the development the drainage-geomorphic system in a hill-gully area on the loess plateau is developed. The model is suitable for the entire process of drainage-geomorphic system. By using this model the erosional cycle in the hill-gully area can be divided into three stages. By quantitatively analysing the Erosional Cycle Theory of Davis and dif-ferent soil erosions at the different stages,non -uniform erosional properties of a drainage-geo-morphic system in space is also founded. In addition,by using that model,an accelerating soil erosional process by human activies and the natural erosion in the hill-gully area is concluded. The model is applied to general drainage-geomorphic systems. An evolutional model of the drainge-geomorphic system with a multicyclic dissipative structure has been expressed. By using the model,the development of the systems has been indicated for different types of drainage-geo-morphic systems. The geomorphic growth mode] is established for the drainge-geomorphic sys-tems, and is verified and tested by experimental data in FGEC.
