摘　　要：基于生态系统服务权衡视角表征土地利用冲突空间范围和强度,并以粤港澳大湾区为例进行区域实证分析。结果发现:1) 2010—2020年,粤港澳大湾区土地利用变化较为剧烈,其中耕地面积减少了1 440.90 km2(减幅为8.20%),而城镇用地面积增加了1 649.92 km2(增幅为28.01%)。2)研究期间区域碳固定、土壤保持和产水量服务呈上升趋势,而食物供给和生境质量服务则呈下降趋势。其中,粮食供给和碳固定的高增益区以及产水量与土壤保持的高减损区均主要分布在研究区的西南部和西北部。3)研究区的土地利用冲突指数为1.05,土地利用冲突较强。主要原因是研究区权衡服务类型较多,且权衡关系较强。各分区的土地利用冲突强度由强到弱依次是自然或半自然区域(1.10)>半自然-半人工区域(0.97)>人工区域(0.77)>半自然区域(0.45)。4)空间分布特征方面,研究区土地利用冲突空间分布范围以弱冲突和中等冲突区域为主,但局部区域土地利用冲突较为剧烈。冲突等级从研究区外围到中部整体呈中等—弱—中等的空间分布结构。China is currently facing a critical period of economic transformation and social development,with land use being under tremendous pressure,facing multiple challenges.The imbalance in land use structure is becoming increasingly prominent and conflicts over various land uses are becoming more intense,thereby attracting an increasing focus.Land use conflict refers to the inconsistent and disharmonious land use methods and quantities among stakeholders in the process of land resource utilization,as well as the conflicting states between various land use methods and environmental aspects.The study of land use conflicts can provide important references for stabilizing land use structures,alleviating land use conflicts,and optimizing the allocation of national spatial resources.Identifying the spatial range and intensity of land use conflicts is a prerequisite for alleviating regional land use pressure.However,existing research has thus far provided insufficient characterization of the negative ecological and environmental effects of land use.The concept of ecosystem service trade-offs is advantageous regarding expressing the negative effects of land use conflicts and their inherent causes.Therefore,based on the perspective of ecosystem services,this study identifies the intensity and spatial distribution characteristics of land use conflicts in the Guangdong-Hong Kong-Macao Greater Bay Area in different types of space using ecosystem service trade-off analysis.Results show that from 2010 to 2020,land use change in the Guangdong-Hong Kong-Macao Greater Bay Area was relatively drastic,with a decrease of 1,440.90 km2(8.20%)in arable land area and an increase of 1,649.92 km2(28.01%)in urban land area.During the study period,carbon fixation,soil retention,and water production services exhibited increasing trends,whereas food supply and habitat quality services exhibited decreasing trends.High-gain areas of food supply and carbon fixation,as well as high-loss areas of water production and soil retention,were mainly distribu
