中文摘要：
对GIS的模糊性进行研究，主要目的是系统论证GIS确实含有模糊性，使人们真正认识到GIS不仅含有随机不确定性而且含有模糊性；从GIS构成的硬件、软件、人员和数据4部分出发，分别对这4部分论述其模糊性；经过系统的研究，得到了GIS的4部分在许多方面都含有模糊性，即GIS数据模糊性、GIS硬件模糊性、GIS软件模糊性和GIS人员的模糊性；最后指出GIS的模糊性研究还处于初级阶段，特别是人员的模糊性还有很多因素无法进行研究，探讨了如何减弱GIS各部分模糊性的理论以及方法。
英文摘要：
The paper researches GIS fuzziness whose main purpose is to demonstrate by the numbers that GIS contains fuzziness, and make people really realize that GIS not only contains random uncertainty but also fuzziness. The paper mainly discusses GIS fuzziness from four parts that are GIS hardware, GIS software, GIS data and GIS person. Through system research, it draws an conclusion that GIS four parts include fuzziness in many aspects that are GIS person fuzziness, GIS hardware fuzziness, GIS software fuzziness and GIS data fuzziness. At last, it points out that research on GIS fuzziness is in primary phase and many problems needed solving such as many factors about person fuzziness haven＇ t good methods to consider. So how to weaken and deal with GIS fuzziness is a urgent problem.
