盐碱地“变身”光伏电站，看东营如何平衡生态与能源

Core Insights - The innovative practice of "photovoltaics + ecology" in Dongying addresses the development paradox of fragile ecological areas by transforming saline-alkali land into a renewable energy base, achieving over 2 billion kilowatt-hours of annual electricity generation [1][2] Group 1: Ecological Restoration and Energy Production - Dongying utilizes the unique characteristics of saline-alkali land, where photovoltaic panels reduce surface evaporation by 40% and increase soil moisture by 15%-20%, creating a suitable environment for salt-tolerant plants [2] - The "fishing and solar complementarity" model allows for dual use of water resources, with a 100 MW project generating 120 million kilowatt-hours annually, saving 36,000 tons of standard coal and increasing fish and shrimp yield by 30% [2] Group 2: Economic Benefits and Ecological Safety - By June 2025, investments in saline-alkali photovoltaic projects in Dongying are expected to exceed 8 billion yuan, creating over 5,000 jobs, with local farmers earning an additional 24,000 yuan annually [3] - Strict adherence to ecological protection principles ensures that photovoltaic projects do not encroach on core wetlands or affect the Yellow River's flood flow, maintaining a harmonious relationship with the national nature reserve [3] Group 3: Technological Innovation and Long-term Governance Challenges - Dongying faces challenges such as long soil improvement cycles, high initial costs, and the need for integrated technology for photovoltaic panel maintenance and pest control [4] - The strategy to overcome these challenges involves a dual approach of technology and mechanisms, including collaboration with research institutions and establishing a benefit-sharing model for ecological restoration [4]
