摘要：

We report on the results of the CCD photometry in the B- and V- band of 8250 stars belonging to the Local Group dwarf irregular galaxy NGC 3109. Color-magnitude diagrams and luminosity functions are constructed. The overall distribution of blue and red supergiants is given. Eighteen OB associations are identified from Halpha maps, and their color-magnitude diagrams are discussed. A catalog of previously known and newly identified H II regions is presented. The star-forming properties that we infer from these data for NGC 3109 are similar to those of other dwarf galaxies.
