摘　　要：精准识别土地利用冲突是国土空间治理的重要前提。该研究引入一个基于土地利用多宜性、土地资源稀缺性和需求多样性的土地利用冲突识别新框架,系统评估粤港澳大湾区土地利用冲突。结果表明:1)粤港澳大湾区土地利用冲突以中等为主,占比高达43.67%;其次为高冲突(29.80%),低冲突区域所占比例最小(26.53%)。2)粤港澳大湾区土地利用冲突呈现显著的城乡差异特征。高冲突区集中在城镇和城乡过渡地带,尤其是城镇化快速发展的惠州市、江门市以及肇庆市;中冲突地区广泛分布在乡镇生产生活区域;低冲突区分布在土地利用适宜性低的山地丘陵地区。3)土地利用高冲突区域耕地和生态用地适宜性高,并且土地资源稀缺性普遍较高;中冲突区主要由于土地资源稀缺性、人类需求多样性高导致。在国土空间利用及相关规划中,应充分考虑潜在的土地利用冲突,建立土地利用冲突预警机制,并纳入相关规划监督实施体系,为优化国土空间格局提供科学依据。Land use conflict has been one of the most important global issues in recent years.Accurate and rapid identification of land use conflicts can be the essential prerequisite to realizing the sustainable use of land resources.The optimization of territorial spatial patterns is also of great significance for the scientific,rational and efficient protection and utilization of land resources.Generally,the land use conflicts can be attributed to the scarce land resources,land use multi-suitability,and demand diversity.However,only a few studies have been used to identify land use conflicts from the three dimensions.Taking the Guangdong-Hong Kong-Macao Greater Bay Area as the study area,this study aims to identify the land use conflicts using"multi-suitability-scarcity–diversity".Firstly,the theoretical mechanism of land use conflict was analyzed using human-land coordination,ecological security,multifunctional theory of land use,Maslow’s hierarchy of needs theory,and land resource scarcity.A new framework was constructed to identify the land use conflict using land use multi-suitability,land resource scarcity,and demand diversity.The multiple objective evaluation was performed on the multi-suitability,scarcity and demand diversity of land use.The spatial overlay analysis function was then used to measure the land use conflict index in the Arcgis platform.Finally,the spatial pattern of land use conflict was quantitatively described during this time.The results showed that:1)There was mainly medium(48.23%)with a wide distribution in the multi-suitability of the land use.The land resource scarcity was mainly medium(49.67%).The spatial distribution was also the pattern of the"decreasing from the middle to the periphery"in the areas with the rapid urbanization development.The demand diversity was mainly low demand(73.29%)with the spatial distribution of the"high in central and south,low around".2)The degree of land use conflict was mainly moderate(43.67%),indicating a spatial feature of gradual decline from the rural-ur
