The aim of this thesis is the study of approximations and rates of convergence for functionals of large dicsrete graphs towards their limits. We contemplate two cases of discrete graphs: trees (i.e. connected graphs without cycles) and dense simple finite graphs. In the first case, we consider additive functionals for two models of random trees: the Catalan model for binary trees (where a tree is chosen uniformly at random from the set of full binary trees with a given number of nodes) and the simply generated trees (and more particulary the Galton-Watson trees conditioned by their number of nodes).Asymptotic results are based on scaling limits of conditioned Galton-Watson trees. Indeed, when the offspring distribution is critical and with ...
