摘要：
We present the first determination of the near-infrared k-band luminosity function of field galaxies from a wide-field K-selected redshift survey. The best-fit Schechter function parameters are M* = -23.12 + 5 log h, alpha = -0.91, and phi* = 1.66 x 10(-2)h(3) Mpc(-3). We estimate that systematics are no more than 0.1 mag in M* and 0.1 in alpha, which is comparable to the statistical errors on this measurement.
