摘　　要：随着地理学从定性向定量的发展,地理学研究中逐渐引入了分形理论。描述分形的特征是分形维数,但现有的地理信息系统软件不能直接用于计算分形维数,研究者需要借助地理信息系统软件进行二次开发实现相应的功能。设计了经常使用的Bouligand维数的算法并借助MapX组件实现了该算法,并通过实例论证了该算法的准确性。With the development of Geography from qualitative to quantitative,fractal theory had been greatly introduced into geographical research.Fractal was measured by fractal dimension which could be not directly calculated with present geographical information system(GIS) software.Researchers need carry on a secondary development based on GIS software to calculate it.Algorithm of the frequently-used Bouligand dimension was designed and implemented using MapX component in this paper.The algorithm was proved correct through an example.
