摘要
对近年来国内外遥感监测土壤盐碱化的研究进展作了介绍,并从土壤盐碱化遥感信息特性和影响因素、各种遥感数据源、数据处理方法和研究热点等方面做了总结。土壤盐碱化的遥感方法和传统方法可获取多源的数据,包括来自多平台遥感的光谱数据、地面实测和实验室分析数据、其它研究手段得到的地理相关数据以及历史资料等。在G IS技术支持下的多源数据集成方法可对土壤盐碱化进行定量探测,在土壤盐碱化遥感应用中取得了较好的效果。
In this paper, the national/international developments in study of remote sensing application of soil salinization recently are reviewed and summarized, including features and interference of soil salinization information in remote sensing, sources of remote sensing data, methods of image processing,and focus of remote sensing applications in this field. By means of remote sensing and conventional methods, such as aerial and satellite remote sensing, ground-based inspecting and chemistry analyzing,geographical methods, and historical data studying, etc. , kinds of data about soil salinization can be got.Good quantified results have been achieved from data integration and synthetic analysis, supported by GIS tools, by some specialists and scholars, in recent years.
