随着人口和资源使用的不断增加，水质和水资源管理将成为主要问题。遥感以其覆盖面积大、空间分辨率高、更新频繁、质量稳定等优点，在水文研究和水资源管理中得到了广泛应用。本文重点讨论了遥感在东亚水文分析中的三个潜在功能：（1）监测浑浊湖泊的水质;（2）从流域中提取不透水面（ISAs）;（3）估计半干旱地区的蒸散量。回顾上述三个专题的结果，可以清楚地看到，目前的遥感技术在水文模拟方面的能力仍然有限。改进传感器的另一种方法是开发有效的算法来补偿当前卫星传感器的局限性。版权所有© 2008约翰威利父子有限公司。
As human populations and resource use continue to increase, water quality and water resource management will become major problems. With its advantages of large area coverage, high spatial resolution, frequent update and consistent quality, remote sensing has been widely used for hydrological studies and water resources management. This paper focuses on three potential functions of remote sensing for hydrological analysis in east Asia: (1) monitoring water quality in turbid lakes; (2) extracting impervious surface areas (ISAs) from watersheds and (3) estimating evapotranspiration in semi‐arid areas. Reviewing the results of the above three topics, it becomes clear that the ability of the current remote sensing technique is still limited in terms of its use in hydrological simulations. An alternative to improving the sensors is developing effective algorithms to compensate for the limitations of current satellite sensors. Copyright © 2008 John Wiley & Sons, Ltd.
