摘　　要：为了丰富了GIS基础理论,运用区间运算理论和集合论,根据定性距离约束条件,导出了定性距离推理的通项公式,重点研究了同向定性距离推理和反向定性距离推理。只要定性距离的区间范围单调递增,推理结果与具体的区间比值无关。根据吸收律,定性推理结果与相邻定性距离的区间范围之比有关。该研究成果。In this paper,the formulae of qualitative distance reasoning are derived based on the interval operation theory,set theory and the constraint conditions for the qualitative distance.Also,the paper focuses on the investigation on the qualitative distance reasoning for the same direction and the inverse direction.If the interval of qualitative distance monotonically increases,the qualitative distance reasoning is not related with the ratio of the adjacent qualitative distances.According to the absorbing law,the reasoning results are related to the ratio of adjacent qualitative distances.provides some insights for GIS theory.
