摘　　要：本文用模糊数学中的多层次模糊综合评判原理对GIS质量进行评价。结果表明模糊综合评价方法不仅能够比较全面地考虑各种因素的影响及其相互作用,实现对GIS质量的合理、定量分析,并能在一定程度上反映出影响GIS质量的关键因素,为进一步提高GIS质量提供决策依据,而且该方法使用简单,结果具有科学性和合理性。本文首次提出用多层次模糊综合评判的方法对GIS质量进行评价,并且把对GIS质量评价进行量化处理。The paper evaluates GIS quality using principle about multi-levels fuzzy synthesis judgment of fuzzy mathematics.The conclusion manifests that the method of multilevel fuzzy synthesis judgment can not only consider effects of all factors and their action each other on GIS quality,and realize reasonable and fix quantify analysis on GIS quality,and provide a decision on improving GIS quality because it reflects keyword factor that affects GIS quality in a certain extent,but also is simple、 practical、 scientific and reasonable.The paper is the first to pvovide this method to evaluate GIS quality and to quantify GIS quality evaluate quantity on GIS quality.
