中文摘要：
文章对GIS的模糊不确定性进行了研究，主要目的是系统论证GIS确实舍有模糊不确定性，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不确定性。文章主要是从GIS构成的四部分出发即：硬件、软件、人员和数据，分别对这四部分论述其模糊不确定性，即GIS存在着GIS数据模糊不确定性、GIS硬件模糊不确定性、GIS软件模糊不确定性和GIS人员的模糊不确定性；最后，指出GIS的模糊不确定性的研究还处于初步阶段，特别是人员的模糊不确定性还有很多因素无法进行研究以及如何减弱GIS各部分的模糊不确定性的理论和方法。
英文摘要：
The paper researches GIS fuzzy uncertainty, and the main purpose is to demonstrate by the numbers that GIS contains fuzzy uncertainty, and make people really realize that GIS not only contains random uncertainty but also fuzzy uncertainty. The paper mainly discusses GIS fuzzy uncertainty 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 fuzzy uncertainty in many aspects that are GIS person fuzzy uncertainty, GIS hardware fuzzy uncertainty, GIS software fuzzy uncertainty and GIS data fuzzy uncertainty. At last, it sums up and point out that research about GIS fuzzy uncertainty is in primary phase and many problems need to be solved such as many factors about person fuzzy uncertainty haven＇t good methods to consider and how to weaken and deal with GIS fuzzy uncertaihty is an urgent problem.
