摘要
碱蓬遥感是滨海盐沼植被遥感的重要部分.本文以中国知网、ScienceDirect、Web of Science为主要数据库,通过检索过去50余年滨海湿地碱蓬遥感论文成果,归纳了碱蓬遥感研究发文量的年际变化情况,探讨了碱蓬遥感的研究进展、存在问题和未来展望.论文总结了发文量的年际变化情况,将碱蓬遥感研究划分为空白期、萌芽期和发展期3个阶段,从碱蓬光谱特征、信息提取、生物物理和化学参数反演、退化机制和碳储量估算方面进行研究综述,指出存在的问题并对未来研究提出4点建议.本研究可为全面了解碱蓬遥感发展现状、准确把握碱蓬遥感研究前沿、深入挖掘碱蓬遥感潜在研究热点提供重要参考.
Abstract
Suaeda salsa remote sensing is an essential part of remote sensing for coastal salt marsh vegetation.Based on China National Knowledge Infrastructure(CNKI),ScienceDirect,and Web of Science,this paper re-viewed the studies of Suaeda salsa remote sensing over the past 50 years.It summarized the annual changes in the publication of Suaeda salsa remote sensing research,discussed the research progress,identified existing is-sues,and provided future prospects.The paper categorized the annual changes of publication volume into three stages:blank period,germination period,and development period for Suaeda salsa remote sensing studies.The comprehensive review of research progress was carried out in terms of spectral characteristics,information extrac-tion,biophysical and chemical parameter inversion,degradation mechanisms,and carbon storage estimation.It al-so highlighted existing issues and proposed four suggestions for future research.This study serves as an important reference for understanding the current development status of Suaeda salsa remote sensing,accurately grasping the forefront direction of Suaeda salsa remote sensing research,and exploring potential research hotspots in depth.
