| 中文摘要: |
| 土壤退化已成为一个全球性的问题，严重威胁生态环境和粮食安全。遥感技术具有高效、省时和研究范围广的特点，近些年在土壤退化研究方面得到广泛应用。本研究通过回顾国内外关于遥感技术在土壤侵蚀、荒漠化、盐渍化和污染等方面应用的研究成果，整理分析了基于遥感技术监测和评价土壤退化的直接指标（土壤矿物成分、有机质、水分等）和间接指标（植被指数、土地利用/覆盖变化），列举了监测和反演这些指标的数据源与具体方法，从而系统地阐述了遥感技术在不同土壤退化类型方面的应用进展，并对遥感技术在该方面的应用进行了展望与讨论。 |
| 英文摘要: |
| Soil degradation has become a global issue that seriously threatens the ecological environment and food security. Remote sensing has been widely used to investigate soil degradation as it is highly efficient, time-saving, and has a broad-scope. We reviewed the application of remote sensing in soil erosion, desertification, salinization, and pollution. The direct(mineral composition, organic matter, and moisture content of soil, etc.) and indirect(vegetation, land use, and coverage change) indices to estimate and evaluate soil degradation using remote sensing were comprehensively summarized. The specific methods and types pertaining to remote sensing data were also examined. The future development and prospective use of remote sensing in terms of soil degradation were discussed. |
