"沙戈荒"风光互补电站气候-生态效应的多情景比较评估OA

To objectively assess the comprehensive climate-ecological impacts of different multi-scenario layouts of wind-solar hybrid power stations,this study develops a multi-scenario comparative assessment framework covering layout design,climate simulation,and ecological response,based on a self-developed meteorological-wind-solar coupling model and an ecological process mechanism model.Taking Alxa in Inner Mongolia and Hami in Xinjiang as case studies,four representative scenarios were designed under two constraints:maximizing stability of joint wind-solar generation and equal-area layout,while considering spatial relationships along the prevailing wind direction.Subsequently,a series of controlled numerical experiments were carried out.The results indicate that the climate-ecological effects of wind-solar complementary power stations are jointly influenced by layout plans,regional climatic conditions and climate change characteristics,showing distinct spatial differentiation characteristics.Therefore,during the planning of large-scale wind-solar bases in Sandy Arid Gobi regions,multi-scenario comparison should be carried out considering regional climate characteristics to provide a scientific basis for new energy development,local climate stability and ecological protection.
