多重约束下的土地利用空间优化研究

Research on optimization of land use space under multiple constraints

过去的土地利用模式往往呈现低密度、低效益的趋势,亟需一种有效的可持续土地利用空间优化方法来平衡经济发展、环境保护与社会公平之间的矛盾。文章在常规用地数量约束和用地转换约束的基础上,对空间约束、生态约束、行政约束等多重约束条件进行分析与数学表达,构建了多重约束下土地利用空间优化模型。同时,以大丰区实验区为研究范围,通过不同约束条件对土地利用空间优化的影响分析,证明了考虑多重约束条件的必要性及构建多重约束下的土地利用空间优化模型可实现土地利用的空间布局和综合效益优化。

Land use patterns show a trend of low density and low efficiency in the past,therefore,there is an urgent need for an effective sustainable land use spatial optimization method to balance the contradiction between economic development,environmental protection and social equity.On the basis of conventional land use constraints count and land use constraints,multiple constraints such as space constraints,ecological constraints and administrative constraints are analyzed and mathematical expressed,a land use space optimization model with multiple constraints is constructed.At the same time,taking the experimental area of Dafeng District as the research scope,the impact of different constraints on the optimization of land use space are analyzed.It proves that the necessity of considering multiple constraints and the land use space optimization model under multiple constraints can realize the spatial layout and comprehensive benefit optimization of land use.
