Abstract：
Based on the recommended level density formula of the Fermi gas model and considering the modifications at low excitation energy,a synthesis level density formula is proposed.From the mean neutron resonance spacing D_exp for 248 nuclei and the cumulative numbers of levels for 529 nuclei,a set of parameters is determined.
