The invention provides a roof formed by steel-membrane space combination structure units based on rigid support and a membrane tensioning method of the roof. The roof comprises a space supporting grid of a crossed rod system; the space supporting grid is a rigid supporting system formed by connecting a series of rigid supporting units; the surface of each rigid supporting unit is covered with a membrane unit, the adjacent membrane units are connected, and therefore the whole complete steel-membrane space structure whole roof is formed; the rigid supporting system comprises a supporting unit and a jacking unit; and the jacking unit comprises a jacking device and a loop jacking ring, and the loop jacking ring is tensioned or adjusts the membrane tension of each membrane unit through the movement of the jacking device. According to the roof, the supporting system of the membrane structure is fully utilized to increase the overall rigidity and coordinate deformation of the roof, so that deformation of a large-spa
