摘要:

全球湿地质量退化, 数量减少, 湿地资源面临巨大压力, 遥感技术在实时、动态监测其变 化方面扮演着一个重要的角色。本文湿地遥感监测主要侧重于基于遥感技术的湿地分类与识别, 从基于遥感监测的湿地分类系统、影像预处理、多分辨率(多空间分辨率、多光谱分辨率、多时相 分辨率)遥感影像数据源、湿地信息提取方法(人工目视解译和计算机自动解译)等方面的国内外 研究现状进行了系统的论述, 并指出目前湿地遥感监测存在3 点不足及其未来研究的6 个重点。

Abstract:

Wetland is one of the most important ecosystems, and it has high social benefit, economic benefit and scientific research value. Global wetland degraded and its amount decreased in the past several decades. Wetland resources are taking on a heavy pressure, and romote sensing technique plays an important role in real- time monitoring of dynamic changes of wetlands. In this paper, wetland monitoring mainly means classification and recognition of wetland based on remote sensing technique. Current status of researches on wetland monitoring based on remote sensing technique in China and abroad was systematically discussed from multiple aspects, including classification systems of wetland, pre - processing of images, remote sensing data sources of multi - resolution (multi - spatial resolution, multi - spectral resolution,multi - temporal resolution), methods of information extraction for wetlands(visual interpretation and computer auto- interpretation) and so on. Finally, three current shortcomings and six future keys of wetland monitoring based on remote sensing were presented.

Key words: current status, prospect, remote sensing, wetland
