摘　　要：构建一种基于模糊概念格的气象云图识别关系模型.此模型选取2个相邻时刻的卫星云图进行云团移动研究,求出每个云团的属性评估值,得到两时刻云团间的评估关系;以评估关系为对象,以云团的特征为属性建立模糊概念格,利用相似度确定相同云团;最后,通过实例证明了以该模型为基础建立的气象云图识别方法更具精确性和实用性.The relation model of nephogram recognition based on fuzzy concept lattice is constructed for focusing on the problem of nephogram recognition. In this model, two satellite nephograms at adjacent moment are chosen for the research on the movement of cloud cluster. The steps are, firstly, to work out the attribute evaluation value of each cloud cluster, get the evaluation relationship between the cloud clusters at the two moments; secondly, with the evaluation relationship as the object and the features of the cloud clusters as attribute, to establish a fuzzy con- cept lattice; thirdly, to determine the same cloud clusters based on similarity. Finally, it is proven by real example that the nephogram recognition method based on this model is more accurate and practical.
