摘要： Ｄｉｊｋｓｔｒａ算法是地理空间数据分析、处理、查询以及决策等的一种实用算法。讨论了应用系统中权值的特点，当权的值具有不确定性时，即权值是动态变化时Ｄｉｊｋｓｔｒａ算法的具体应用。

Abstract: Dijkstra algorithm was practical when the geography space data was analysed and handled. Some weight features of an applied system were discussed in this paper. Dijkstra algorithm was given at a dynamic weight system.
