摘要：In this paper, a constructive method is presented for Lagrange interpolation set in a given bivariate spline space from the view of the generator basis of modules. Some results and necessary conditions for Lagrange interpolation set in S21(  22(2)) and S31(  22(1)) are given. The mentioned method can be easily extended to study the problem of Lagrange interpolation set in any multivariate spline space.
