Abstract：
The transverse momentum spectra for identified hadrons at different
rapidities in central Au+Au collisions at √s_NN= 200 GeV are studied in a quark combination model. The results for p_T spectra of π^±, K^±, p(p) and for the p/π ratios in a broader p_T range at midrapidity agree well with the data. The transverse momentum spectra of pions, protons and antiprotons at various rapidities y~1, η=2.2 and y≈3.2 are calculated and compared with the data.
