摘要:

在显著气候变化叠加人类活动干扰的背景下,可持续的湿地生态系统管理对于湿地空间信息的需求不断提升,湿地遥感作为重要的交叉学科方向,研究成果日益增多。本文以Web of Science核心合集为数据库,通过检索过去50年湿地遥感论文成果,总结了湿地遥感研究全球发文量和引文量的变化情况;进行文献计量分析,探讨湿地遥感研究的发展历程和发展趋势。论文将湿地遥感研究划分为潜力探索期、框架成型期、快速增长期三个阶段,进而总结分析了不同阶段湿地遥感的研究主题和主要数据源;最后基于VOCviewer软件对湿地遥感研究热点关键词进行综述,从大数据时代背景下的湿地遥感分类及景观动态、精细化的湿地生态参量遥感观测、湿地可持续管理空间决策支持三个方面进行了未来研究趋势的展望。本研究将为理解国际湿地遥感研究发展历史、把握湿地遥感研究国际前沿、进行国内湿地遥感研究布局提供借鉴。

A Review of global studies in remote sensing of wetlands from 1975 to 2020
Abstract:

Given the evident climate change impacts and human disturbances on wetlands, sustainable ecosystem management requires more wetland spatial information. As one of the important interdisciplines, remote sensing of wetlands has increasing publications. Here, we searched the published papers in the past 50 years from the database of “Web of Science Core Collection”. We summarized the changes in number of publications and citations and the development process and trend in remote sensing of wetlands. We divided the development history into three research periods including potential exploration phase, framework emerging phase, and rapid growth phase. We also concluded the main research topics and data sources in different phases and analyzed the hotspots in remote sensing of wetlands by the extracted keywords from the latest 500 and top-cited 500 papers. Three outlook bullets were presented from the wetland classification and landscape dynamics in the era of big data, the fine remote sensing observations in wetland ecological variables, and the spatial decision-support for sustainable wetland management. The review is expected to benefit understanding the development history and international frontiers for studies in remote sensing of wetlands and support the layout of domestic researches in remote sensing of wetlands.
