  Let $S$ be a closed orientable surface with genus $g\geq 2$. For a sequence
$\s_i$ in the Teichm\"uller space of $S$, which converges to a projective
measured lamination $[\lam]$ in the Thurston boundary, we obtain a relation
between $\lam$ and the geometric limit of pants decompositions whose lengths
are uniformly bounded by a Bers constant $L$. We also show that this bounded
pants decomposition is related to the Gromov boundary of complex of curves.
