摘　　要：本文总结近年来国内外空间关系的研究进展,介绍现今已提出的关于方向关系的描述模型并对已有的方向关系模型做了比较和举例说明;从空间认知的角度出发,以面目标作为参考目标,对参考目标本身加入细节方向关系,从而对基于锥形的方向关系模型进行改进,并用实例对已有方向关系模型进行比较来说明改进后的锥形模型的优越性,扩展了方向关系的描述。The paper firstly summarized the research progress of the spatial relation in domestic and abroad in recent years, intro- duced the spatial relationship, and then made a comparison with current direction relation models and illustrated them. Previous direction relation descriptive models took the reference objects as ＂the same one＂ direction, which is obviously deficient. For a more de- tailed and accurate deseription of direetion relations, this article took surface targets as reference targets from the perspective of spatial cognition, and added detail direetion relations to the reference targets to improve the direction relation models that are based on taper. Lastly, this text made comparison on existing direction relation models by taking examples to illustrate the superiority of the improved taper models, which was proved to extend the description of direction relations.
