摘　　要：根据区间II型模糊集理论研究了高阶模糊地理实体的方向表示方法,提出以方向场描述其方向隶属度,以分区方向场代替原始方向场,研究了高阶模糊地理实体的方向关系分析方法,给出了方向场的隶属度误差和方向关系的隶属度误差表示方法。There are lots of fuzzy phenomena in real world,and scale effect exists in modeling those phenomena,so high order vagueness exists in geographical world.The modeling of high order fuzzy object and their direction relation is complex and difficult.The direction representation of high order fuzzy geographical object is analyzed based on interval Type II fuzzy set.And the direction space is used to describe the direction membership value,and the divided direction space is used to replace initial direction space.The analysis method of direction relation between high order fuzzy objects is studied,and membership value error representations of direction space and direction relation are proposed.
