摘　　要：应用地理信息系统(GIS)技术提取了莱州湾东岸河流信息,在此基础上运用计盒方法对莱州湾东岸的黄水河和王河水系进行了分形分析,获得了两水系的主河道河长分维数和河网分维数,并以此探讨了分维数与流域地貌和地质构造之间的相互关系。分形分析为研究区流域地貌学与水文学研究提供了一种新的研究途经。Using geographic information system (GIS) technology, the information of river channels in the eastern coast of Laizhou Bay can be obtained. Then, with traditional box-counting method, it is possible to perform fractal analysis of two rivernets of the Wanghe river and Huangshuihe river and obtain their dimensions of the river main channel and the rivernet. Moreover, the relationship between the dimension of river channels and topography and geological construction is discussed. It goes without saying that the fractal analysis can bring forward a new method for the study of topography and watershed hydrology in the eastern coast of Laizhou Bay.
