We have studied several quantized levels in the low temperature magneto-conductance of the quantum dot array system fabricated by a split-metal-gate technique on GaAs/AlGaAs 2DEG layer. The gate-voltage dependence of the effective g-value at high fields has been discussed in the dot array. It is noted that the depopulation effect at the quantum point contacts leads to a large decrease of the effective g-value.
