提出了一种融入方向关系矩阵模型思想的改进型锥形模型。该模型同时具备了两者的优点，尤其对多尺度空间目标的空间方位关系的表达比较有效．并顾及到了多尺度的包容性。
英文摘要：
A improved cone-shaped model is given in order to improve the old cone-shaped model. The new improved spatial direction-relation makes use of the ideas of both cone-shape model and direction-relation matrix model, which inherits their merits at same time, especially heightens the ability greately to express the spatial direction-relation between spatial objects effectively under the muilti-sacle circumstance, and the muilti-scale compatibility is considered.
