We present a statistical study on possible association between the unidentified γ-ray point sources at the Galactic plane (|b|<=5°) and the Galactic young pulsars with ages of less than 106yr. Our results suggest that young pulsars may account for the majority of unidentified EGRET sources that are positionally associated with supernova remnants and OB star asociations, in such a way that two thirds are young radio quiet pulsars and one third are young radio pulsars. We have studied the variability of these unidentified γ-ray sources and found that most of them may be non-variable. Furthermore, we expect that GLAST may detect ≍80N.100 radio pulsars and ≍1100N.100 unidentified γ-ray point sources in the Galactic plane with |b|<=5°, where N.100 is the birth rate of neutron stars in units of 100 years.
