  We present a scenario wherein the anomalous U(1) D-term of string origin
triggers supersymmetry breaking and generates naturally a Split Supersymmetry
spectrum. When the gaugino and the Higgsino masses (which are of the same order
of magnitude) are set at the TeV scale, we find the scalar masses to be in the
range (10^6 - 10^8) GeV. The U(1) D-term provides a small expansion parameter
which we use to explain the mass and mixing hierarchies of quarks and leptons.
Explicit models utilizing exact results of N = 1 suersymmetric gauge theories
consistent with anomaly constraints, fermion mass hierarchy, and supersymmetry
breaking are presented.
