The invention provides a greenhouse combining aluminum-alloy glass structure with membrane structure, which comprises a greenhouse aluminum-alloy frame, wherein four sides of the aluminum-alloy frame are provided with vertical wall surfaces consisting of glass. The greenhouse is characterized in that the top of the aluminum-alloy frame is provided with a top consisting of membrane fabric. Compared with common glass greenhouses, the greenhouse has the advantages that the top of the greenhouse is a membrane structure which is light in dead weight, can relatively reduce steel consumption,is graceful in shape, rich in modern characteristics and capable of providing tall space, is provided with a few vertical columns inside to ensure more flexible division of indoor space, has good light transmittance (about 7 to 20 percent), can meet demand for natural lighting in the daytime, as well as the growth need of crops, and is fast to construct, not easy to accumulate water and smooth to drain water.
