Abstract A model considered gas outflows due to supernova explosions is developed for the star formation and chemical enrichment for the globular clusters(GCs) in the Milky Way Galaxy. Through Monte-Carlo simulations, the observed global properties of GCs can be well reproduced, including the metallicity distribution, no-correlation between cluster masses and galactocentric distances, etc. The predicted mass function of the parent clouds for the observed GCs at present-day can be well described as a power law with the index of -1.8, which is consistent with the current observations for the molecular clouds.
