海草光学遥感监测研究综述

海草生长在热带、亚热带和温带海洋水域, 是全球海洋生态系统中重要的结构和功能组成部分, 具有极高的生态服务价值。由于受到人类活动和自然灾害的强烈影响, 海草正在全球范围内快速衰退, 因此开展海草资源监测与保护具有非常重要的意义。随着传感器技术的发展, 光学遥感在海草监测中表现出卓越优势。本文综述了国内外海草遥感监测研究现状, 重点总结了研究内容、技术和方法, 论证了海草光学遥感监测的可行性, 旨在为我国海草光学遥感监测厘清适宜数据和可靠技术方法, 并指明潜在研究方向。同时也希望能为海草遥感监测提供借鉴, 并拓展海草资源科学管理的思路。

Review on the research of seagrass optical remote sensing monitoring

Seagrass growing in the waters of tropical, subtropical and temperate oceans is an important structural and functional component of the global marine ecosystem and has a high ecological service value. Seagrass is rapidly declining worldwide because of the strong impact of human activities and natural disasters. Therefore, it is a great significance to monitor and protect seagrass resources. With the development of sensor technology, optical remote sensing has shown obvious advantages in seagrass monitoring. In this paper, we review the research status of advanced seagrass remote sensing monitoring at home and abroad, mainly summarizing the research content, technology and methods, and demonstrating the feasibility of seagrass optical remote sensing monitoring. Our aim is to illustrate the suitable data and reliable technical methods for seagrass optical remote sensing monitoring in China, and to suggest potential research directions. This review provides reference for seagrass remote sensing monitoring and expands the thought of scientific management of seagrass resources in China.
