陕西关中地区土地资源的优化配置

从分析陕西省关中地区土地资源利用现状结构特征及存在问题入手,运用灰色线性规划模型对土地利用结构进行优化配置。模型选取多个影响土地利用结构因子,并通过预测未来关中地区各行各业之用地需求及用地限制从而确定出各因子适当参数,进行模拟后得出典型备选方案。最后从综合效益及可行性双方面考虑,经层次分析法择出未来关中地区最优土地利用决策方案。

Land use structure optimization for Guanzhong Region,Shaanxi Province

Based on the analysis of the present land use structure and existing problem related to such land use patterns in Guanzhong Region,Shaanxi Province,this paper applies gray linear programming model (GLP) to the optimization of land use structure in the Region.Several typical solutions for the future land use structure have been simulated out by the model,through the selection of a set of factors deciding land use structure,and through the calculation of parameters of land supply,land use requirements and limitations,and various land use demands.The optimized scheme of future land use structure for the Region has been decided at the end with the analytic hierarchical programming method (AHP) in which both comprehensive benefits and feasibility are considered.
