The invention relates to a production method of artificial stones for landscapes. The method provided by the invention has the advantages of large benefit, low cost, and reuse of wastes. Raw materials for producing the artificial stones comprise desulphurization wastes, rubber powder, coloring powder and water. The desulphurization wastes are a main thermal power plant flue gas desulphurization product and mainly contain calcium sulfate hemihydrate and other impurities, a die is filled with the calcium sulfate hemihydrate and the other impurities as a filler, the coloring powder and water are added, the obtained mixture is stirred and shaped, and a stone like paint is sprayed on the external surface of the shaped filler. The filler contains many impurities, the artificial stones are heavier and more stable than artificial stones obtained by only using pure gypsum, the impurities contain divalent iron ions, the divalent iron ions react with water and oxygen to generate trivalent iron ions, and a compound existing in a trivalent iron ion form has greatly increased stability and hardness, so the hardness of the artificial stones produced in the invention increases with the span of the outdoor rain time.
