摘要
较系统地论述了分形理论在水文水资源中的应用。主要包括:水系河网结构和流域地形地貌及其演变,河床表面形态,降水时空分布,洪水时空变化,径流过程和土壤水下渗等。概括了当前在应用中的特点:活跃思想和方法创新,同时指出值得注意的问题:在大量资料基础上进行深入分析和充分论证。
This paper deals more systematically with the application of fractal theory in many aspects to hydrology and water resources, including the structure of river network, the topography of basin, the surface geometry of river bed, the distribution of rainfall in time and space, the variation of flood in time and space, the process of runoff, the movement of ground water and infiltration. The characteristics which occur in the practice of the application of the fractal theory to hydrology and water resources shows the activity thinking and the creation in methodology for hydrology. Attention should be paid to the verification of the reasonable basis for such application based on a great deal of data.
