With the increasing demand for accurate and reliable hydrological information, geo-spatial analysis plays a more and more important role in hydrological studies. The development of the geo-spatial technique advances our understanding of the complex and spatially heterogeneous hydrological systems. Meanwhile, how to efficiently and effectively process and analyze multi-source geo-spatial data has become more challenging in the fields of hydrology. In this editorial, we first review the development and application of geo-spatial analysis in three major topics in hydrological studies, namely the scaling issue, extraction of basin characteristics, and hydrological modelling. We hence introduce the articles of the Special Issue. These studies present the latest results of geo-spatial analysis in different topics in hydrology, and improve geo-spatial analytic methods for better accuracy and reliability.

水文学中的地理空间分析

随着对准确，可靠的水文信息的需求不断增长，地理空间分析在水文研究中发挥着越来越重要的作用。地理空间技术的发展提高了我们对复杂的空间异质水文系统的理解。同时，在水文学领域，如何有效地处理和分析多源地理空间数据变得越来越具有挑战性。在这篇社论中，我们首先回顾水文研究中三个主要主题的地理空间分析的发展和应用，即规模问题，盆地特征的提取和水文建模。因此，我们介绍了特刊的文章。这些研究提供了水文学中不同主题的地理空间分析的最新结果，
