Title: 光学光谱成像在植物盐胁迫早期检测中的应用：综述

Abstract: Salinity stress poses a significant challenge to global agriculture, necessitating efficient and scalable approaches for early detection and management. This review examines advanced optical spectroscopic imaging techniques, including fluorescence imaging, hyperspectral imaging, and thermal imaging, for their ability to detect physiological and biochemical responses in plants subjected to saline conditions. By focusing exclusively on imaging-based optical methods and excluding traditional spectroscopic techniques, the review emphasises non-invasive tools capable of delivering high sensitivity and specificity. These technologies enable real-time, high-throughput analysis, making them particularly well-suited for large-scale plant screening and breeding programs targeting salt tolerance. The integration of ground-based optical systems with aerial platforms such as unmanned aerial vehicles and satellites significantly expands spatial and temporal monitoring capabilities.
