The paper depends on the new three theories(theory of dissipative structure.catastrophe theory and synergetics)as a guide,and establishes a developmental strategy planning forthe circumjacent reservoir regin of Longtan hydropower project which is the dragon head station often-cascade development along the Red Water Rlver,and adopts grey systems theory to predict theeconomic development of the reservoir region, The computational results show that the grey predic-tion model,the theory and methods of grey systems applying to economic system prediction are effi-clent.
