光伏治沙，鄂尔多斯还需克服哪些“坎”

Core Insights - Ordos City, known as "China's coal capital," has been a leader in photovoltaic (PV) desertification control, benefiting from reduced sandstorms and increased solar power generation in recent years [1][2][4] Group 1: Photovoltaic Desertification Control - The 2 million kW PV desertification project in the Kubuqi Desert, initiated in June 2022, is expected to generate 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 utilizes a dual function of PV panels for power generation and sand fixation, creating a "small greenhouse" effect that promotes plant growth [3][4] - Ordos has approved a total of 39.79 million kW of PV capacity, with 10.02 million kW already built, and plans to achieve over 3 million acres of PV desertification control upon full project completion [5] Group 2: Economic and Agricultural Benefits - Local farmers have benefited economically from planting vegetables like tomatoes under PV panels, with reported incomes of 50,000 yuan from 12 acres of cultivation [2][3] - The integration of solar water pumps and precision drip irrigation has effectively addressed irrigation challenges in desert areas, enhancing vegetation productivity and soil quality [6] Group 3: Future Development and Challenges - Experts highlight the need for standardized construction and recognition criteria for PV desertification projects to facilitate broader implementation [7][8] - Recommendations include promoting successful models of renewable energy and ecological restoration, and developing policies to encourage the integration of PV with other agricultural and ecological projects [7][8]
