Land scarcity in China intensifies conflicts between photovoltaic (PV) infrastructure and agricultural, ecological, and urban land uses. This study addresses the gap in county-level research by proposing a novel framework integrating land-type clustering, multi-objective optimization, and geospatial simulation to evaluate sustainable land use under PV expansion scenarios. Analyzing 562 counties in central and eastern China, counties are categorized into woodland-dominant, farmland-dominant, urban-dominant, and balanced types. Three scenarios are assessed: PV development (PV), business-as-usual (BS), and low-carbon emission (CE). The PV scenario balances BS and CE, curbing carbon source expansion while protecting farmland—e.g., farmland in Cangnan (woodland-dominant), Sheyang (farmland-dominant), and Lingbao (balanced) counties increased by 1.09 %, 2.35 %, and 1.1 % versus CE. Farmland-dominant and balanced counties show high adaptability, with economic and environmental benefits rising 67 % and 37 %. Urban-dominant counties have limited PV potential, and woodland-dominant counties are unsuitable for large-scale PV, with total benefits dropping 1 % and ecological impacts rising. Medium-density PV (80 % coverage) maximizes returns, with a 20.25-year payback. Policies should prioritize PV on agricultural and construction lands in farmland-dominant and balanced counties, while protecting ecology in urban- and woodland-dominant ones to support carbon neutrality.

中国的土地稀缺加剧了光伏基础设施与农业、生态和城市土地利用之间的冲突。本研究提出了一种整合土地类型聚类、多目标优化和地理空间模拟的新型框架来评估光伏扩张情景下的土地可持续利用，以弥补县级研究的空白。通过对中国中东部地区562个县域的分析，将县域划分为林地主导型、农田主导型、城市主导型和均衡型。评估了三种情景：光伏开发（PV）、一切照旧（BS）和低碳排放（CE）。光伏方案平衡了BS和CE，在保护农田的同时抑制了碳源的扩张。苍南县（林地优势）、射阳县（农田优势）和灵宝县（平衡）的耕地面积比CE增加了1.09 %、2.35 %和1.1 %。耕地优势县和耕地均衡县表现出较高的适应性，经济效益和环境效益分别提高了67 %和37 %。城市优势县光伏潜力有限，林地优势县不适合大规模光伏发电，总效益下降1 %，生态影响上升。中密度PV（80% %覆盖率）回报最大化，投资回收期为20.25年。在以耕地为主、耕地平衡的县域，政策应优先考虑农业用地和建设用地的光伏发电；在以城市和林地为主的县域，政策应优先保护生态，以支持碳中和。

As the world accelerates its low-carbon transition, the rapid expansion of centralized solar photovoltaics (PV) has received extensive concerns on land-use competition and environmental trade-offs. Here we construct a spatially explicit assessment framework to quantify the ecological and economic implications of PV land occupation across 367 mainland Chinese cities in 31 provinces. We integrate high-resolution PV infrastructure mapping with baseline land-use classifications and region-specific indicators of land productivity, economic output, and terrestrial carbon sequestration. This combined dataset is used to estimate land occupation, food loss, and reductions in terrestrial carbon sinks, and to design city-level spatial optimization and wind–solar substitution scenarios. enabling a comprehensive. By 2020, centralized PV installations occupied 1910 ± 116 km² of land, and the footprint is projected to exceed 30,000 km² by 2060. While grasslands and barren lands comprise the largest shares by area, cropland, occupying only 22 % of the total land, accounts for most agricultural and carbon sink losses due to its high biomass productivity. Moreover, the study also identified widespread land–value mismatches, where many cities disproportionately convert their most economically valuable land. City-level spatial optimization scenarios show that relocating 30 % of PV to lower-value land could halve food and carbon sink losses, and that substituting terrestrial and offshore wind for PV in selected cities could probably reduce land use by more than 90 %. These findings highlight the need to integrate ecological and economic value into solar siting and national decarbonization planning.

随着全球向低碳转型的加速，集中式太阳能光伏发电的迅速发展引起了土地利用竞争和环境权衡的广泛关注。本文构建了一个空间明确的评估框架，以量化中国大陆31个省份367个城市光伏用地占用的生态和经济影响。我们将高分辨率光伏基础设施测绘与基线土地利用分类以及土地生产力、经济产出和陆地碳封存的区域特定指标相结合。该组合数据集用于估算土地占用、粮食损失和陆地碳汇减少，并设计城市级空间优化和风能-太阳能替代方案。启用全面。到2020年，集中式光伏装机占地面积为1910±116 平方公里，到2060年预计占地面积将超过30,000 平方公里。虽然按面积计算，草原和荒地所占比例最大，但农田仅占土地总面积的22% %，由于其高生物量生产力，造成了大部分农业和碳汇损失。此外，该研究还发现了普遍存在的土地价值错配，许多城市不成比例地转换了最具经济价值的土地。城市层面的空间优化情景表明，将30% %的光伏转移到价值较低的土地上可以使粮食和碳汇损失减半，而在选定的城市中，用陆地和海上风电取代光伏可能会减少90% %以上的土地利用。这些发现强调了将生态和经济价值纳入太阳能选址和国家脱碳规划的必要性。

Against the urban duality challenges of the Global South under high urbanization pressure, (1) rapid urbanization versus emerging population decline, (2) formal planning systems versus informal urban growth, and (3) global urban development versus local community management, planning tools of Japan, which experienced rapid urbanization would be effective, but not as a model but as a reference. This paper aims to set a viewpoint on how selected Japanese strategic planning tools, that is, agile master planning, urban growth boundaries, and basic building regulations, can serve the Global South cities by interpreting them from the concepts of policy mobility, lesson-drawing, and hybridity.

Through illustrative case studies from the selected cities of Asia, Africa, and Latin America, the analysis demonstrated that Japan’s tools offer heuristic value in addressing key dualities. And it highlighted that Japanese planning principles act as a catalyst, prompting reinterpretations and the co-production of hybrid knowledge in diverse contexts of the Global South. In turn, the insights gained from those processes would offer valuable lessons for Japan's own contemporary challenges. Recognizing this two-way learning loop is the key to moving beyond one-way policy transfer and fostering a truly global planning culture rooted in collaborative problem-solving.

面对高城市化压力下全球南方国家面临的城市二元性挑战，(1)快速城市化vs新兴人口下降，(2)正式规划体系vs非正式城市增长，(3)全球城市发展vs地方社区管理，经历快速城市化的日本的规划工具将是有效的，但不是一种模式，而是一种借鉴。本文旨在通过对日本战略规划工具——敏捷总体规划、城市增长边界和基本建筑法规——从政策流动性、经验借鉴和混合性的概念进行解读，阐述日本战略规划工具是如何服务于全球南方城市的。通过来自亚洲、非洲和拉丁美洲选定城市的说明性案例研究，分析表明日本的工具在解决关键的二元性方面提供了启发式价值。它还强调，日本的规划原则起到了催化剂的作用，促使全球南方国家在不同背景下重新解读和共同生产混合知识。反过来，从这些过程中获得的见解将为日本自己当前面临的挑战提供宝贵的经验教训。认识到这种双向学习循环，是超越单向政策转移、培养一种植根于协作解决问题的真正全球规划文化的关键。
