Abstract: A non-isospectral KdV equation with self-consistent sources and its Lax pair are given. N-soliton solution is obtained with the Hirota method, and non-isospectral dynamics of the 1-soliton solution obtained are investigated.

Key words: exact solution, Hirota method
,
self-consistent sources, non-isospectral KdV equation
