摘　　要：全域土地综合整治用地优化是满足不同整治目标下差异化的用地需求,缓解潜在用地冲突的重要途径。以海南省儋州市全域土地综合整治起步区国家级试点项目区为研究区,基于生态价值增长目标与生态产品价值实现目标之间的权衡,为全域土地综合整治用地设定生态价值优先和生态产品价值实现潜力优先两种整治情景,以2019年试点项目区三调成果为现状,运用多目标规划模型和GeoSOS-FLUS模型分析两种整治情景下的用地结构优化和用地布局优化。结果表明:生态价值优先整治情景下,与现状相比,试点项目区红树林地和水田规模增加明显;整体景观分离程度较高,分布更加均衡且破碎。生态产品价值实现潜力优先整治情景下,与生态价值优先整治情景相比,试点项目区红树林地和水田增加规模有所变小,但商业服务业用地规模明显增加;整体景观进一步破碎化。两种整治情景的用地布局与《儋州市全域土地综合整治起步区国家级试点实施方案》中的全域土地综合整治建设项目布局相似与差异并存。因此全域土地综合整治若增加生态价值与提高生态产品价值实现潜力需要统筹配置各用地类型,同时也要关注优化用地后可能对景观格局产生的影响。Land use optimization in comprehensive land consolidation can meet the different demands for land under different objectives and alleviate potential land use conflicts.The national pilot project of comprehensive land consolidation in Danzhou city in Hainan province is selected as a case in this study.This paper sets two scenarios for comprehensive land consolidation including ecological value priority and realization potential of ecological product value priority under the trade-off between the increasing ecological value and realization potential of ecological product value.And the land use optimization is based on the third national land resource survey of the pilot project.Then the multi-objective programming model and GeoSOS-FLUS model are employed to optimize the land use structure and land use layout under two scenarios in comprehensive land consolidation.The results show that:(1)Compared to the land use status in 2019,the areas of mangrove forest and paddy field significantly increase under the ecological value priority scenario in the pilot project zone.The overall landscape exhibits a high level of polymerization,while evenness and fragmentation levels are relatively high.(2)Compared to the ecological value priority scenario,the areas of mangrove forest and paddy field decrease under the realization potential of the ecological product value priority scenario in the pilot project zone.And the areas of commercial and service land significantly increase.The level of landscape fragmentation of the overall landscape increases as well.(3)There are similarities and differences between the land use layout under the two scenarios and the construction project layout of comprehensive land consolidation in the Implementation Plan for the National Pilot Project of Comprehensive Land Consolidation in the Starting Zone of Danzhou City.Therefore,the areas and spatial layout of different types of land for increasing ecological value and realizing the potential of ecological product value should be considered overall in t
