A method of monotonicity-preserving quadratic spline Hermite interpolation is proposed .The method preserves the monotonicity of a points sequence by setting appropriate knots slopes based on the deep research of previous methods .Meantime, a strict proof is provided.After that, a points sequence experiment is carried out to test the performance of the method proposed in this paper .The result of experiment shows that the method can interpolate the points sequence to a monotonicity -preserving and smooth curves .So the method is of the excellent performance in monotonicity-preserving interpolations .
