基于逐步宽容约束法的土地利用优化配置研究

土地利用结构调整是土地利用总体规划的核心内容,对城市土地资源的集约、高效利用有着重要意义。本文以逐步宽容约束法(GECM)为基础,以经济效益、生态效益最大化为目标,构建涉及土地面积、土地利用结构、宏观计划等方面约束条件的多目标线性规划模型,对广州市花都区土地利用结构进行优化配置研究。研究结果表明,逐步宽容约束法协调了各区域、部门之间的目标冲突,实现了土地利用空间格局的合理配置;同时,指出未来区域内土地利用结构总体变化不大。通过该方法对现有土地利用空间结构进行优化,以提高土地利用技术水平,有效配置土地资源与空间资源,促进花都区社会经济的可持续发展。

LAND USE OPTIMIZATION ALLOCATION BASED ON GRADUAL EASY CONSTRAINT METHOD (GECM)

 Adjustment of land use structure is essential to land use planning, which is of great importance to promote intensive, efficient and sustainable utilization of urban land resources. Based on GECM, this paper aims to maximize the economic and ecological profits, establishes a multi-objective linear planning model with constraints of land area, use structures and macroscopic planning, optimizes the land use structures in Huadu district, Guangzhou city. The results indicate that GECM can resolve the conflicts among regions and departments, and reach a rational allocation in land use structure. There is little change in the future land use structure. This method, as proven, can optimize the land use structure, increase the land use technology, effectively allocate land resources and space resources, and promote a sustainable development of Huadu district’s economy and society.
