The cartography takes up a very concernful station in the geographic information system, and it is the demand of various maps production units. Along with the computer technology development at present, the cartography already did not need depend upon the manual manufacture completely, The people often expected the roboticized, function strong, intelligentized computer output replaces the miscellaneous artificial work .At the same time, the output effect must approach the manual effect as far as possible.In the real life, there are a mass of statistical data. These data although all include the geography attribute, but, many usually by the writing form appearance, the form is stiffness and many information are not easily to discover. Therefore, we needs to express by the thematic map form in order to obtain a more direct-viewing exhibition, besides we can excavate the new information. The thematic map is a powerful method which is used for analyzing and representing data, it may provide the basis for user's decision-making.Therefore, Aiming at the publish of by Geography teaching research institute grouped by countrywide university and the Chinese map publishing company, The article has studied some relational questions about the designing and the realization in thematic map establishment in the ArcGIS foundation and established the dynamic thematic map in Liao-Ji-Hei regions which had the region characteristic in this foundation. This article structure is:Part 1: Introduction. This part mainly expatiate the cartography development actuality, the request of map charting as well as the relation between GIS and the digital charting.Part 2: The rationale of thematic map drawing. This part mainly summarizes the content, development process, composing, designing, as well as the data disposal of thematic map.Part 3: Thematic map establishment process based on GIS.This part mainly embarked from the manufacture of the thematic map using GIS, explain the application which the technology of GIS in drawing of thematic map, as well as the preparative of special data, the collection of datum, the analyses of data, the designing of thematic map and the output of map in the process of thematic map drawing based on GIS. Then illuminate the predominance of GIS in the process of the thematic map drawing.Part 4: Dynamic thematic map establishment in Liao-Ji-Hei regions based on GIS.This part mainly started from the compile of the partition designing script of Liao-Ji-Hei regions. By analyzing and disposing the data of base map in the thematic map. Aiming at the different special content, the article adopted different thematic map drawing methods, then drawing the thematic map. In the process of drawing, the data were dealt with by combining the software GIS and RS.Part 5: Conclusion and expectation. This part mainly summarized the study production of the article as well as the elicitation. Further more, bring up future research expectationThis article taken the statistical data in Liao-Ji-Hei regions'three provinces for example, which include1950, 1985, 2000 and 2004, which has completed some thematic map drawing, for example the grain, the forest, the cultivated land and the industry structure thematic map were drawing.
