Abstract: Based on the collection and analysis of the basic geological data of Xingjiang Tacheng Basin and on the GIS technology, a synthetic stratum section database for Tacheng Basin was established and a synthetic stratum historgram drawing model was designed and used to complete the automatic drawing of the relevant form, the labeling of writing information and the making, mapping and managing of lithological symbols. The lithological symbol database was established and each symbol coded, realizing the automatic symbolized expression of all lithological historgrams by matching the attribute codes of historgrams with those of corresponding lithological symbols. The technology is an improvement of the conventional drawing of synthetic stratum historgram.

Key words: Synthetic stratum historgram, Database, ArcGIS, Lithological symbol
