摘要：This paper takes the cloud model into land price information inquiry, using cloud model to express the spatial concept and the attributes of spatial entity described with qualitative language, it integrates the fuzziness and randomness of land price spatial information and attribute information and then realizes the quantitative conversion of qualitative language. At last, it realizes the uncertain inquiry of land price data with the help of GIS.The results shows that this method integrates the fuzziness and randomness, which makes the inquiry results more random and agglomerate, and gets more flexibility and representationalism than the fuzzy query method based on the fuzzy sets
