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.
