Evaluation of the basic support role of farmland water conservancy infrastructure construction for food security
农田水利基础设施建设对粮食安全的基础性支持作用评估

摘要

在全球人口增长与环境变化背景下，粮食安全成为焦点。农田水利基础设施宛如农业根基，从多维度保障粮食稳定产出。一方面，其完善灌溉体系，依作物需水精准供水，提升单产；另一方面，抵御旱涝灾害，减少粮食减产损失。还能优化水土资源，拓展种植边界，降低生产成本，激发农户积极性。综合这些关键作用，深入剖析其对粮食安全的支撑效能，对稳定全球粮食供应意义重大。

Abstract

Against the backdrop of global population growth and environmental changes, food security has become a focal point. Agricultural water infrastructure serves as the foundation of agriculture, ensuring stable grain production from multiple dimensions. On one hand, it improves irrigation systems to provide precise water supply according to crop needs, thereby increasing yield per unit area. On the other hand, it helps mitigate drought and flood disasters, reducing grain loss. Additionally, it optimizes water and soil resources, expands planting boundaries, reduces production costs, and boosts farmers' enthusiasm. By comprehensively analyzing these critical functions, deeply understanding its support for food security is crucial for stabilizing global grain supply.
