摘　　要：文中结合大连市区地质灾害调查与区划项目,建立了一套基于GIS的地质灾害易发程度分区评价模型。并将多级模糊模式识别模型引入到地质灾害易发程度分区评价中,研究和探讨GIS与地质灾害易发程度分区评价模型的结合,为解决地质灾害调查与区划项目中地质灾害易发程度分区提供新的理论方法。Taken Dalian district's investigation of geologic disaster project analyzes as its geology environment background,the thesis sets up the divided district assessment model of frequent geologic disaster's level.The model which to be lead by muti-classification fuzzy pattern recognition model,discuss combining GIS with frequent geologic disaster's level of district assessment model is a new method that deals with the geologic disaster investigation and divided district project and provide a new theoretical method.
