【摘要】 利用分形特征定量描述水系空间特征的研究方兴未艾,以1∶5万河流数据为基础,用计盒维数和Horton定理2种水系分维数估算方法估算,并比较了太湖流域不同子流域的水系分维特征。结果表明,太湖流域水系的分维具有河长分维北小南大、河网分维西小东大的特点。更多还原

【Abstract】 The application of fractal theory has been largely developed since it was used in hydrology in 1980’s.The river network fractal dimension of each subbasin in Taihu basin using box dimension and Horton theorem based on river network data on the scale of 1∶50000 was computed in the paper.The results show that both of stream length fractal and river network fractal have the cha-(racter) of spatial difference.更多还原
