光伏治沙，中国鄂尔多斯还需克服哪些“坎”

Core Viewpoint - Ordos, known as "China's coal capital," has been a leader in the field of photovoltaic (PV) desertification control, benefiting from reduced sandstorms and increased solar power generation, but still needs to address sustainable development challenges in the future [1][4]. Group 1: Photovoltaic Desertification Control - The 2 million kW PV desertification project in the Kubuqi Desert, initiated in June 2022 and expected to be completed by December 2023, will generate an average of 4.1 billion kWh annually, saving 1.23 million tons of standard coal and reducing CO2 emissions by 3.198 million tons [2][3]. - The project area has nearly 1,000 acres of medicinal herbs and organic fruits and vegetables using modern water-saving planting techniques, contributing to agricultural economic benefits [3]. - The integration of PV and desertification control is seen as a sustainable model, utilizing the natural complementarity of resources in China's vast desert areas [3][4]. Group 2: Policy and Development Challenges - Ordos has approved a total of 39.79 million kW of PV capacity, with 10.02 million kW already built and 29.77 million kW under construction, aiming to achieve over 3 million acres of PV desertification control [5][6]. - Experts highlight the need for standardized construction and recognition criteria for PV desertification projects to avoid potential ecological damage during implementation [7][8]. - Recommendations include promoting successful models of renewable energy and ecological restoration, and developing policies to encourage the integration of PV with desertification control [7][8].
