Abstract: Creating programs for decision-making by different ways, which can provide abundant information and alternative ones in optimum allocation of land resources, is the basis for optimizing allocation of land resources. But few people carry out the researches on how to create decision-making program. Combining extension engineering and goal-programming model, a method for constructing an extendable goal-programming model that can create programs by different perspectives was put forward. Then taking Xi county of Shanxi Province as an example, the method was applied in the extendable programming model for land resources allocation. The result shows that the method for land resources allocation based on the extendable goal-programming model performs rather well by changing objects, conditions and decision variables.
