中文摘要：

RGB模型支持下的色彩合成技术能够实现模糊c-均值算法（FCM）输出结果的连续制图表达,但RGB模型本身的条形图例不能很好地反映出制图结果的空间信息和模糊不确定性信息。同时当模糊类别数量较多的情况下,容易出现新生成的类别色彩与原类别色彩相近甚至重复的现象,从而导致最终的模糊连续制图出现类别混乱的问题。研究表明基于HSI模型的轮式图例不仅可以反映出模糊类别之间的属性空间距离（亲疏关系）,同时可以反映出制图结果的空间信息和模糊不确定性信息。两个色彩模型的有效结合较好地实现了色彩合成技术支持下的土壤模糊连续制图。

英文摘要：

Color mixture technology can realize the continuous results of soil map through fuzzy c-means algorithm under the RGB model support.But the linearity legend of RGB color model cannot reflect the spatial information and the fuzzy uncertainty information of the charting result well.If there are many categories,the phenomenon will easily appear that the new category color close to or even repeat the original color categories.Thus the category chaotic problem will be caused in the final fuzzy continuous mapping.This research paper indicates that wheeled legend of the HSI model can not only reflect the attribute space distance between the fuzzy categories（friend or stranger relates）,but also reflect the spatial information and the fuzzy uncertainty information of the charting result.The effective combination of the two color models will realize the fuzzy continuous mapping well under the color mixture technology support.
