光伏发电作为一种重要的可再生清洁能源，是我国新能源产业的核心组成部分.科学规划光伏产业空间布局是项目成功实施的前提.研究以淮安市盱眙县为例，通过地类筛选、限制因素分析、聚合度分析和图斑形态分析，对全域光伏产业用地的空间布局特征进行研究.结果表明：受自然资源禀赋的影响，盱眙县适宜发展光伏产业的地类以坑塘水面和其他林地为主；产业用地布局受地类、“三区三线”、河湖管理线等因素影响较大，而历史文化保护线的影响相对较小；县域内可用于光伏产业的适宜图斑聚合距离在200 m以下，当距离为500～600 m时聚合度趋于稳定，有利于形成片区；地类、地形是影响图斑形态的关键因素.综合研判，盱眙县西北部片区和山脉周边片区适宜大规模开发光伏项目.

As a crucial form of renewable and clean energy,photovoltaic(PV) power generation constitutes a core component of China' s new energy industry.Scientifically regulating its spatial layout is a prerequisite for the successful implementation of PV projects.Taking Xuyi County in Huai'an City as a case study,this research systematically investigated the spatial layout characteristics of land suitable for the PV industry through land type screening,constraint factor analysis,aggregation analysis,and patch morphology analysis.The results indicated that,influenced by natural resource endowments,the primary land types suitable for PV development in Xuyi County were pond water surfaces and other forest land.The spatial layout of potential PV sites was significantly constrained by factors such as land use type,the "Three Zones and Three Lines" spatial control policy,river and lake management lines,while the impact of cultural protection lines was relatively minor.Analysis of patch aggregation revealed that the distance between suitable patches was predominantly below 200 meters,with the degree of aggregation stabilizing at distances between 500 and 600 meters,which facilitated the formation of developable clusters.Land type and topography were identified as key factors influencing patch morphology.Comprehensive evaluation suggests that the northwestern region and the areas surrounding mountains in Xuyi County are suitable for large-scale PV project development.
