    In this paper, we show that every (weighted) Bergman space Aαp(Bn)\mathcal{A}^p_{\alpha} (\mathbb{B}_n) in the complex ball admits an atomic decomposition of real-variable type for any 0−1.0 -1. More precisely, for each f∈Aαp(Bn)f \in \mathcal{A}^p_{\alpha} (\mathbb{B}_n) there exist a sequence of real-variable (p, \8)_{\alpha}-atoms aka_k and a scalar sequence {λk}\{\lambda_k \} with \sum_k | \lambda_k |^p < \8 such that f=∑kλkPα(ak),f = \sum_k \lambda_k P_{\alpha} (a_k), where PαP_{\alpha} is the Bergman projection from Lα2(Bn)L^2_{\alpha} (\mathbb{B}_n) onto Aα2(Bn).\mathcal{A}^2_{\alpha} (\mathbb{B}_n). The proof is constructive, and our construction is based on some sharp estimates about Bergman metric and Bergman kernel functions in Bn.\mathbb{B}_n.Comment: 28 page
