Core Insights - The integration of photovoltaic (PV) development with desertification control is seen as a strategic necessity for energy transition and ecological restoration [1][3] Group 1: Photovoltaic Development Plans - During the 14th Five-Year Plan, the Three-North region is expected to add 253 GW of new PV capacity and rehabilitate 10.1 million acres of desertified land [1] - The National Energy Administration and the National Forestry and Grassland Administration have issued guidelines to promote the integration of PV projects with desertification control in several provinces [3] Group 2: Ecological Impact of Photovoltaic Projects - A PV project established before 2018 showed an annual increase of approximately 10% in vegetation density, indicating a positive effect of PV on local flora [2] - The construction of PV stations has been linked to a 40% increase in biomass, a 13% reduction in average wind speed, an 18% increase in humidity, and an 80% rise in vegetation coverage [3] Group 3: Ecological Assessment Methodology - A comprehensive ecological assessment framework has been developed, incorporating various indicators such as vegetation coverage and biodiversity, to evaluate the ecological impact of PV stations [1][2] Group 4: Recommendations for Planting Strategies - Recommendations for planting in PV stations include selecting low-growing, drought-resistant plants that do not interfere with energy production, with a focus on local species [4] - Three planting strategies are proposed: ecological-oriented, pasture-oriented, and economically viable crops, with an emphasis on controlling plant height to mitigate fire risks [4]
