Abstract

The photovoltaic poverty alleviation (PVPA) project in China integrates clean energy production into poverty reduction, gaining significant academic interest. However, a systematic assessment of the spatial distribution and emission reduction performance of existing PVPA power plants at the site level remains deficient. Based on comprehensive data collection and spatial visualization of all PVPA plants, we revealed spatial distribution patterns and estimates potential environmental benefits for each plant. During 2013–2019, the construction of approximately 180-thansand PVPA plants in China had resulted in an overall installed capacity of 21.77 GW. The spatial layout showed a decreasing trend from east to west, with distinct clusters at the border areas of different provinces. The cumulative emission reduction benefits amounted to 636 million tons, with large-scale solar photovoltaics and the North China Grid contributing significantly. Emission reduction efficiency per unit of installed capacity in the north was higher than the south. This study provides an initial site-level assessment of the PVPA program in China and emphasizes the need for integrating economic feasibility and environmental benefits, along with developing complementary policies and exploring innovative “photovoltaic plus” channels tailored to local contexts in the future.

中国光伏扶贫项目的空间格局与环境效益

中国的光伏扶贫(PVPA)项目将清洁能源生产与减贫相结合，引起了学术界的极大兴趣。然而，从场址层面对现有聚乙烯醇电厂的空间分布和减排绩效进行系统评估仍显不足。基于对所有PVPA植物的综合数据收集和空间可视化，我们揭示了每个植物的空间分布模式，并估计了每个植物的潜在环境效益。2013-2019年期间，中国建设了约180万座PVPA工厂，总装机容量为21.77吉瓦。空间布局呈现自东向西递减的趋势，各省区边界地区集聚明显。累计减排效益6.36亿吨，大型太阳能光伏和华北电网贡献显著。北方单位装机减排效率高于南方。本研究对中国的PVPA项目进行了初步的现场评估，并强调需要将经济可行性和环境效益结合起来，同时制定互补政策，探索未来适合当地情况的创新“光伏+”渠道。

期刊介绍： Environmental Impact Assessment Review is an interdisciplinary journal that serves a global audience of practitioners, policymakers, and academics involved in assessing the environmental impact of policies, projects, processes, and products. The journal focuses on innovative theory and practice in environmental impact assessment (EIA). Papers are expected to present innovative ideas, be topical, and coherent. The journal emphasizes concepts, methods, techniques, approaches, and systems related to EIA theory and practice.
