摘　　要：量化图形具有形象直观、一目了然的效果,很容易被读者所理解和接受,并能很快形成具体概念,实现地学量化信息的高效传输.曲轴坐标系作为量化图形展现的数学基础之一,它的创立突破了直轴坐标系的局限,把坐标轴选取的范围由直线轴扩展到曲线轴,引入了曲轴、曲率、轴向、曲向等图形变量,拓展了量化图形制图空间,丰富了量化图形表现形式,为地理数据的图形可视化表达提供了新的途径.探讨了曲轴坐标系的构成原理、构成条件及现有直轴坐标系的演化方法,说明了曲轴坐标系创立的制图意义.The quantitative graphs, direct-viewing and understandable, are easily understood and accepted by the readers. It can specify the concrete concept very quickly and realize the geoscience quantitative information being transmitted effectively. As one of the quantitative graphs mathematics foundations, the establishment of curving axis coordinate system breaks through the straight axis coordinate system＇s limitation, expands the coordinate axis selection＇s scope from the straight axis to the curving axis, and introduces graphic variables such as the curving axis, curvature, axial, curving direction and so on. It expands the charting space of quantitative graphs,enriches the quantitative graphs manifestation,and provides a new way for the geography data＇s graph visualization expression. The curving axis coordinate system＇s constitution principle is discussed, the constitution condition and the existing straight axis coordinate system＇s evolutionary methods and the charting significance of its establishment are explained.
