In this paper we have compiled two new open cluster catalogues .
In the first one , there are 119 objects with ages , distances and metallicities available , while in the second one , 144 objects have both absolute proper motion and radial velocity data , of which 45 clusters also with metallicity data available .

Taking advantages of the large number of objects included in our sample , we present an iron radial gradient of about - 0.063 \pm 0.008 dex kpc ^ { -1 } from the first sample , which is quite consistent with the most recent determination of oxygen gradient by nebulae and young stars , which is about - 0.07 dex kpc ^ { -1 } .
By dividing clusters into age groups , we show that iron gradient was steeper in the past , which is consistent with the recent result from Galactic planetary nebulae data , and also consistent with the inside-out galactic disk formation scenarios .
Based on the cluster sample , we also discussed the metallicity distribution , cluster kinematics and space distribution .
A disk age-metallicity relation could be implied from those properties , although we could not give conclusive result from the age metallicity diagram based on the current sample .
More observations are needed for metal poor clusters .
From the second catalogue , we have calculated the velocity components in cylindrical coordinates with respect to the GSR for 144 open clusters .
The velocity dispersion of the older clusters are larger than that of young clusters , but they are all much smaller than that of the Galactic thick disk stars .
