Positive definite integral quadratic lattices(or the associated quadratic forms) have been investigated from various points of views, one of which is a system of generators with some specified lengths. In this paper we will find all lattices over real quadratic integers) which are generated by some vectors the norms of lengths of which are 2 or 3.
