We report the results of an experimental study of the exclusive hadronic decays for D-0 --> K(s)(0)pi(+) pi(-) and (KsK+K-)-K-0 and their resonant structures using BES-I detector at the BEPC Collider. Using the data sample of 22.3 pb(-1) collected at the center-of-mass energy roots = 4.03 GeV, we measured the branching fraction for D-0 --> (K) over bar (0) pi(+) pi(-) to be (5.32 +/- 0.53 +/- 0.40)%, the branching fractions for the decays D-0 --> K* - pi(+), D-0 --> and D-0 --> (K) over bar (0) (pi(+) pi(-))(non-resonant) to be (6.05 +/- 0.32 +/- 0.49)%, (1.17 +/- 0.17 +/- 0.13)% and (1.35 +/-...
