红树植物根去除外界环境（气相、沉积物相和水相）中多环芳烃（PAHs）是环境中PAHs的重要去除途径。因此，大量研究围绕解决环境中（大气、水和沉积物）PAHs进入植物体的途径、在植物体内的迁移路径、赋存情况等一系列相关问题展开。然而，因缺乏合适的红树植物根表皮PAHs的原位分析方法，对于PAHs在红树植物根表皮赋存情况及向组织内部迁移这一红树植物根去除PAHs步骤尚不清楚。鉴于此，本文开展了相关研究，分别构建了激光诱导纳秒时间分辨荧光光谱法（LITRF）、导数激光诱导纳秒时间分辨荧光光谱法（D-LITRF）以及显微荧光光谱法（MFSA）法实现了红树植物根表单/双组分PAHs的原位定量测定，并初步...The depuration of PAHs by mangrove plants in the external environment (gas phase, sedimentary phase and water phase) was one of the important ways to remove PAHs. Therefore, there existed many studies focused on investigate a series of related processes such as the transport pathways and distribution of PAHs in plant. Among them, the process and mechanism of PAHs located on the epidermis and trans...学位：理学博士院系专业：环境与生态学院_环境科学学号：3312014015398
