The invention belongs to the field of building materials and particularly relates to an ecotype high-strength modified gypsum powder. The ecotype high-strength modified gypsum powder is prepared from industrially desulphurized or natural gypsum powder, ground slag, polyvinyl alcohol, fired alunite powder, melamine and borax. The ecotype high-strength modified gypsum powder meets various technical requirements of natural gypsum powder, and is greatly improved in strength grade, runnability, durability and construction property.
