季风亚洲的特点是自然环境和社会环境的多样性。这些环境范围从潮湿的热带地区到干旱地区，存在着各种相关的水文现象。本文试图基于基于网格的全球数据集计算的水收支来描述季风亚洲的水文区域。通过对水的盈余和赤字进行排序，绘制了水文区域地图。从东南亚延伸到日本列岛的大量水分富余湿润带、中国东部从湿润环境到干旱环境的快速过渡以及东南亚大陆的干旱区被湿润地区包围是季风亚洲最显著的特征。这张地图揭示了季风亚洲的一个基本特征是靠近干旱和潮湿的环境。一个地区的许多水问题和水管理实践可以通过在地图上绘制出来很容易理解。几个大的河流流域的边界叠加在地图上，并检查了水的预算和流动状况。研究结果较好地解释了季节径流状态的区域特征。强调了在亚洲季风区使用空间框架进行比较水文研究的重要性。版权所有©2004 John Wiley & Sons， Ltd
Monsoon Asia is characterized by its diversity of natural and social environments. These environments range from humid tropics to arid regions and there exist associated various hydrological phenomena. This paper attempts to characterize the hydrological regions of monsoon Asia based on the water budget calculated using grid‐based global datasets. A map of hydrological regions is created by ranking the value of water surplus and deficit. A humid zone with large water surplus extending from Southeast Asia to the Japanese archipelago, rapid transition from humid to arid environments in eastern China, and an arid region surrounded by a humid region in continental Southeast Asia are the most remarkable features in monsoon Asia. The map reveals that an essential characteristic of monsoon Asia is the proximity of the arid and humid environments. Many water problems and water management practices in a region can be easily understood by plotting them on a map. The boundaries of several large river basins are superimposed on the map, and examined for the water budget and flow regimes. The results are found to explain the regional characteristics of the seasonal runoff regimes satisfactorily. The importance of using a spatial framework for the comparative hydrological study in Monsoon Asia is highlighted. Copyright © 2004 John Wiley & Sons, Ltd.
