空间关系相似性在众领域中具有广泛应用，确定区域间方向关系相似性的研究已较完善，然而这些方法不能直接用于不确定区域间方向关系的相似性度量。本文以扩展的方向关系矩阵EDRM （Extended Direction Relation Matrix）为模型，提出了一种不确定区域间方向关系的相似性度量方法，据此实现了算法SA-EDRM ；随后基于目标对象的位置和比例尺这两种基本的空间变化生成不同场景，对算法SA-EDRM进行测试，由实验结果验证了算法的有效性；最后以农业GIS中的具体应用实例说明本文工作的实用价值。

Similarity of spatial relations is with wide applications in normal life .Research on similarity assessment of exact direction relations is more perfect ,but the presented methods based on crisp regions can not deal with the approximate direction rela-tions .Based on the extended direction relation matrix (EDRM ) ,the paper proposed a method for similarity assessment of approxi-mate direction relations ,and then the algorithm SA-EDRM was implemented ;on the basis of the variation of location and scale of the target object ,different scenarios were generated to test SA-EDRM ,and the experimental results verify the effectiveness of the al-gorithm .In the end ,an instance of Agricultural GIS was used to explain the practical value of this article .
