  We define strongly Gauduchon spaces and the class SG which are generalization
of strongly Gauduchon manifolds in complex spaces. Comparing with the case of
Kahlerian, the strongly Gauduchon space and the class SG are similar to the
Kahler space and the Fujiki class C respectively. Some properties about these
complex spaces are obtained, and the relations between the strongly Gauduchon
spaces and the class SG are studied.
