基于区间数的邯郸市土地利用结构多目标规划

The multi-objective programming of land use structure based on the interval number in Handan

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。基于邯郸市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,采用区间数多目标规划模型对邯郸市土地利用结构进行优化。构建区间数单目标规划模型以确定每个约束目标的希望水平及容忍限,构建辅助模型平衡每个约束目标的规划值,得出各类用地调整后的优化面积,以及土地利用经济效益、生态环境效益、合理用水量,为邯郸市的土地利用规划提供依据。

Adjustment of land use structure is the core content of land use planning, it is of great importance to promote intensive, efficient and sustainable utilization of land resources. Based on characteristics of uncertainty and complexity of land utilization structure in Handan, the paper focuses on using the interval number multi-objective planning model to analyze the adjustment of land use structure of Handan. Through establishing each target expectation and tolerance limit by the interval number single objective programming model, establishing the auxiliary model balance planning value of each single goal, it is reasonable to calculate the adjustment area of various types of land use structure, such as the economic benefit of land use, the ecological environment benefit and reasonable use of water, providing the reference to the decision makers by the case study of Handan and showing the land use multiple objective planning model method is effective.
