摘　　要：应用系统分析技术进行坝系优化规划的研究，建立了一个具有多约束和多变量的非线性规划模型；论述了应用变量分割法求解上述模型与拉格朗日乘子法和罚函数法相比所具有的优越性；在具体实施变量分割法的过程中，通过对变量进基驱动力的研究分析，找到了剔除假可行解的办法，从而应用变量分割法处理奇异函数，且方法简便，紧扣实际，便于推广应用．This paper presents a nonlinear programming model with multiple variables and constraints for optimization planning of a dam system in serious soil erosion regions. The mathematical model described could lead to a solution on the basis of variables partition, and the advantages of this method over others, such as Lagrange Multiplier Method and Penalty Function Method, are explained. In the process for getting a final solution by variables partition analysis on driving force of variables for entering the base has been made and the techniques for eliminating pseudo feasible solutions have been established. Thus, the algorithm presented in this paper has broken the restriCted zone to the method of variables partition due to its unability of dealing with the odd-shaped function. Therefore, the algorithm of this paper could be broadly applied in practice due to their simplicity and closer relation with practice.
