Which produces more oxygen per year: broadleaf or conifer trees?

To increase oxygen production, should we plant deciduous trees or evergreens? The broadleaf seems to have more surface, but their active life is short. We live in the Rockies at 7800 feet.

    I would go with the evergreens..or you could get the best of both worlds and go with the one and only decidious conifer..The Dawn Redwood.
