高中地理教学常将逆温的保温效应简化为普适性原理，而银川平原的冬季案例揭示了这一认知的局限性。本文通过解析该地逆温保温效应有限且引发浓雾的真实案例，旨在将教学重点从记忆定式转向对地理原理适用边界的探究。研究发现，当前地理教学需突破“案例泛化”的误区，转向“原理本地化验证”。本文通过数据对比和递进式三阶探究教学，引导学生辨析地理原理适用边界，培养其地理批判性思维与地理实践力，为破解案例泛化教学困境提供新思路。

High school geography instruction often simplifies the heat-retention effect of temperature inversions into a universally applicable principle, yet the winter case study of the Yinchuan Plain reveals the limitations of this understanding. By analyzing a real-world case where the heat-retention eff ect was limited and led to dense fog, this article aims to shift the focus of instruction from rote memorization to an exploration of the boundaries of geographical principles. The study fi nds that current geography education must move beyond the misconception of“generalizing case studies”and shift toward “localized verification of principles.” Through data comparison and a progressive, three-stage inquiry-based teaching approach, students are guided to analyze the boundaries of geographical principles’applicability, thereby cultivating critical thinking and geography praxis, and off ering new insights for overcoming the challenges of teaching based on generalized case studies.
