西南地区食物安全可持续发展不仅是保障国家食物安全的重要组成部分，而且还关乎生态文明、民族团结与脱贫攻坚等其他国家战略。以绿色和生态为核心的发展方式是保障该区域食物安全可持续发展的重要前提。在调研该区域食物生产现状的基础上，从生态环境特征、农业投入品、农业结构方面分析了可持续发展面临的挑战，并结合西南自身生产条件和资源禀赋，提出了包括总体思路、战略定位、战略目标、发展路径为主要内容的战略构想和以完善政策与实施重大工程为核心的政策建议，旨在为国家制定区域食物安全战略规划提供决策参考。

Sustainable development of food security in Southwest China is critical in ensuring national food security, and concerns ecological civilization construction, ethnic unity, and poverty alleviation in China. A green- and ecological-oriented development approach is an important prerequisite for ensuring the sustainable development of food security in this region. In this paper, we first investigated the food production situation in this region, and then analyzed the challenges from the aspects of ecological environment features, agricultural inputs, and agricultural structure. Furthermore, according to the production conditions and resource endowment of Southwest China, we proposed a strategic vision comprising overall thinking, strategic positioning, general goal, and development path, as well as several policy suggestions focusing on policy modification and project implementation, aiming to provide references for the formulation of regional food security strategies.
