摘要
土地利用结构调整是土地利用规划的核心内容,对促进土地资源的集约、高效和持续利用具有重要意义。基于四川双流县土地资源开发利用的特征和土地利用结构调整的不确定性、复杂性等特点,该文提出采用区间数不确定性多目标规划模型对双流县进行土地利用结构调整。通过设计区间数单目标规划模型来确定每个目标的希望水平及容忍限,建立辅助模型平衡各个目标的规划值,计算得到各类用地调整后的优化面积,以及土地利用效益、生态环境效益和合理用水量,为决策者在土里利用规划中提供参考依据。通过实例研究,表明了土地利用区间数多目标规划模型方法的有效性。
Adjustment of land-use structure is essential to land-use planning, which is of great importance to promote intensive, efficient and sustainable utilization of land resources. Considering the characteristics of the land resources in Shuangliu County, and the uncertainty and the complexity of the adjustment of land-use structure, interval multi-objective linear programming model is applied in the paper. Firstly, the interval single-objective programming model is used to determine the values of expecting level and tolerance bounds of each objective function, and then an auxiliary model is built to balance the planning values of each objective function. By calculation, some useful results are obtained, such as the optimized area of land after adjustment, land-use benefit, ecologically environmental benefit and reasonable water demand, which will provide some useful advice for decision-makers. Case study shows the validity of interval multi-objective programming model.
