摘　　要：以促进耕地集中连片为单一目标的传统土地整治区划工作,已无法满足国土空间生态修复与全域土地整治提出的可持续发展新要求。本文以上海市青浦区土地整备引导区为研究区域,基于多目标优化理论与Pareto最优算法,考虑空间结构、生态价值、环境影响、农业生产潜力等多维度目标,建立基于多目标优化的大都市土地整治潜力区划决策框架。基于权衡视角下的土地整治潜力区划方案显示,青浦区土地整备引导区内总面积近2922公顷(6397个图斑)的区域划入土地整治潜力极高区,占引导区总面积的43.72%。本文提出的多目标最优的大都市土地整治潜力区划决策方法,能较好地处理多目标权衡下的定量求解问题,可对我国区县级重大土地整治项目的规划部署提供技术支持和借鉴。The traditional land consolidation planning is just focus on improving the concentration of cultivated land,which could not meet the new requirements for sustainable development proposed by the ecological restoration of territorial space and all-around land consolidation.This paper incorporated multi-objectives,including spatial structure,ecological value,environmental impact,and agricultural production potential,into the framework of land consolidation potential zoning decision-making,based on multi-objective optimization theory with Pareto optimal algorithm.Taking Qingpu district as a case study,a total of 6397 plots,almost 2922 hm2,was classified into the category showing highest potential to consolidate into cultivated land from the trade-off perspective.The methodology proposed in this paper,could better deal with the quantitative solution problem under the multi-objective trade-off,which can provide technical support for the planning and deployment of major land consolidation projects at the district and county level in my country.
