摘　　要：提出了一种基于分形理论的元分维模型,可以用于描述地图目标的局部形态特征变化,为地图目标的进一步分析应用提供了一个新的思路。As a main factor of fractal geometry, fractal dimension is used to quantificationally analyze the spatial complexity of map objects. But it is proved in practice that a map object usually shows nonuniformity of local fractal character. A meta fractal dimension model is put forward based on fractal theory that can be applied to describe the change of local shape of objects, and a new method for their further applications and analyses is offered.
