摘要：

Using the volume-limited Main galaxy sample of the Sloan Digital Sky Survey Data Release 6, we have explored the dependence of clustering properties of galaxies on the star formation activity. It is found that star-forming galaxies preferentially form isolated, close double and multiple systems, while passive galaxies preferentially inhabit the dense groups and clusters. We also construct the two samples with the same galaxy number and number density, and reach the same conclusion, which shows that our statistical conclusion is robust.
