In this paper,by the properties of X-polynomial,Y-polynomial.Merrifield-Simmons index and Hosoya index,we obtain some inequalities of hexagonal spider for the number of k-matching and k-independent set,Merrifield-Simmons index and Hosoya index.At the same time,we characterize the corresponding extremal graphs.
