Based on singular linear space,this paper defines a set X of subspaces of type(m+1,1)that all contain a fixed subspace of type(m-1,0).According to the different types of the sum of any two subspaces in X,an association scheme with a class number of 5 on X is constructed.Besides,all intersection numbers of the scheme are computed.
