【摘要】 土地荒漠化对全球范围内粮食安全产生巨大威胁，在生态和社会层面产生严重的负面影响，造成巨大的经济损失。随着光伏技术的发展及其产业链的日趋成熟，光伏电站在光热条件优越、土地廉价、干旱半干旱地区大规模建设，光伏治沙技术也随之产生。该技术是将光伏发电、防治沙漠化、节水农业技术相结合的一种创新方法，旨在利用沙漠丰富的太阳能资源进行清洁能源生产，同时通过工程措施、生态措施、光伏治沙单元（即单个电站）的多尺度空间布局来防治沙漠化，改善生态环境，达到生产和生态双赢的效果。通过综合国内外相关文献报道以及本课题组实践经验，梳理了光伏治沙技术的发展轨迹，提出了用于理解光伏治沙理念和效益的光伏-土壤-植被耦合系统，阐明了该技术的基本原理、具体措施和实践意义，并对其研究和实践进行了展望，以期为光伏治沙技术进一步优化及其规模化应用提供参考。更多还原

【Abstract】 Land desertification poses a significant threat to global food security, exerting severe adverse impacts on ecological and social systems, while also resulting in substantial economic losses. With the development of photovoltaic technology and the maturation of its industrial chain, coupled with the favorable solar and thermal conditions as well as cost-effective land availability in arid and semi-arid regions, large-scale construction of photovoltaic power stations has become feasible, and consequently, a novel technique known as photovoltaic desertification control has emerged to effectively combat desertification. This technology represents an innovative approach that integrates photovoltaic power generation, desertification prevention, and water-saving agricultural technology. Its primary objective is to harness the abundant solar energy resources in deserts for clean energy production while simultaneously preventing desertification through a multi-scale spatial layout of engineering, ecological measures, and photovoltaic sand control units(i.e, individual power stations). This comprehensive strategy aims to enhance the ecological environment and achieve a mutually beneficial outcome for both productivity and ecology. Drawing on relevant literature and the practical experience of our research group, this paper provides a comprehensive review of the development trajectory of photovoltaic desertification control technology. It introduces the concept and benefits of the photovoltaic-soil-vegetation coupling system to enhance understanding, while elucidating the fundamental principles, specific measures, and practical significance of this technology. Furthermore, it presents future prospects for research and implementation. The aim of this review is to provide valuable guidance for the further optimization of photovoltaic desertification control technology and its large-scale application.更多还原
