摘  要： Originating in the cartography that represents the regions of the surface of the earth on a Euclidean piece of paper and beginning in the works of Tissot （1880s）Grötzsch (1920s), Lavrentief (1920s) and others, the study of quasiconformal mappings on the n-dimensional  Euclidean spaces  has a rich history of over one hundred years.In an attempt to develop higher-dimensional quasiconformal mappings on metric measure spaces with curvature conditions, i.e. from Ahlfors to Alexsandrov, we will show that the a quasiconformal homeomorphism of a non-collapsed RCD(0, n) spaces  (n ≥ 2) with Euclidean growth volume is quasisymmetric, if it maps bounded sets to bounded sets.
