The invention discloses an aliphatic-aromatic copolyester and PLA (Poly Lactic Acid) block copolymer and a production method and an application thereof and a composition containing the block copolymer, which belong to the technical field of high molecular materials. The aliphatic-aromatic copolyester and PLA block copolymer consists of aliphatic-aromatic copolyester Q and a PLA block, and is taken as a biodegradable material; and the block copolymer can be prepared into a modified PLA material and a modified aliphatic-aromatic copolyester Q material. A product prepared with the method has wide production benefit and economic benefit.
