粮食安全是国家战略核心，地理学科是粮食安全教育的重要载体。本文以新疆伊犁州粮食高产实践为案例，将粮食安全教育融入高中地理“农业区位因素及其变化”教学，设计任务驱动式“地理侦探”课堂教学模式，引导学生理解农业区位优化的逻辑及其对筑牢粮食安全的重要意义。案例教学旨在促进学生地理学科核心素养发展，深化学生对“藏粮于地、藏粮于技”战略的理解，为高中地理教学融合国家战略教育提供实践参考。

Food security constitutes the core of national strategy, and geography serves as a vital carrier for food security education. Taking the grain high-yield practice in Yili Prefecture, Xinjiang as a case, this paper integrates food security education into the senior high school geography teaching of“Agricultural Location Factors and Their Changes”. It designs a task-driven “Geography Detective” classroom teaching model to guide students to understand the logic of agricultural location optimization and its great significance for consolidating food security. The case teaching aims to promote the development of students’geographical key competences, deepen their understanding of the strategies of“storing grain in the land and storing grain in technology,” and provide practical references for integrating national strategic education into senior high school geography teaching.
