Abstract
We describe the Chow ring with rational coefficients of the moduli space of stable maps with marked points 
0,m(ℙn, d) as the subring of invariants of a ring B*(0,m(ℙn, d); ℚ), relative to the action of the group of symmetries Sd. B*(0,m(ℙn, d); ℚ) is computed by following a sequence of intermediate spaces for 0,m(ℙn, d) and relating them to substrata of 0,1(ℙn, d + m - 1). An additive basis for A*(0,m(ℙn, d); ℚ) is given.
