With respect to phonetics, Distinctive Features for the phonetic syncopation of spatial information are extracted based on Bertin's retinal variables. The importance of geographic reality, cognitive laws and geometric laws in the syncopation is pointed out following the thorough inspection of the physical characteristics of spatial information and a phonetic hierarchy of phoneme、 phoneme combination is proposed after the summarization of different methods of syncopation in Psychology, Pattern Recognition, Mathematic Morphology and Cartography, which provides linguistic interpretation for cartographic symbol design and understanding. With respect to the property that map symbol is represented as the combination of attribute and geometry in digital form of spatial information, suprasegmental phoneme as unit is proposed which deals with the high level phonetic units and their structure with the bend of curve and the simple area of complex area as primitive.

Firstly, the distance between stocks are calculated by using prices of stocks, and subdominant ultra-metric space by associating the minimum spanning tree of portfolio. Secondly, the subdominant ultra-metric space to the chart of index hierarchical structure is transformed, and finally the distribution of style is gained. Using sample of Shanghai Stock 50 Index from 2004 to 2007, the demonstration result shows that style of industry is more prominent horizontally, especially in the bank and steel industries. The style of region and cross holding also exists. And after the reform of non-tradable shares, style of industry becomes more obvious vertically and more other styles also occur.
