摘要
本文用分形几何学理论对甘肃中部及其邻近地区进行了水系分析，发现分外值的大小反映了研究区内发生滑坡灾害的程度。研究结果表明，不同区域水系的分维值与滑波的分布数量非常吻合。由此可见，水系分形研究对区域性滑坡灾害的危险度判定有一定的实际意义。
Drainge systems in Mid-Gansu and its neighboring areas have been analysed by fractal geometric theory in this paper from which we have discovered that fractal dimension values reflect the degrees of landslide disaster on study areas. The results demonstrate that fractal dimension values in different drainge systems are identical with quantity of landslide distribution from which fractal study on drainge systems has some practical significance on distingwishing risk of local landslide disaster.
