The invention discloses a runner surface optimization design method, a runner molded surface, an adjustable guide vane design method and a guide vane, coordinates of a front edge point and a tail edge point of an upper vane top or a lower vane top of the guide vane are obtained by cutting an adjustable guide vane blade at a design angle based on an initial runner surface, and then moving tracks of the front edge point and the tail edge point in the angle adjusting process of the adjustable guide vane are obtained; based on the moving track, the flow channel contour of the adjustable guide vane is obtained; the inlet position flow channel contour and the outlet position flow channel are connected to form an optimized flow channel after being subjected to shape modification and fairing; and based on the optimized flow channel, cutting the adjustable guide vane in different mounting angle states to generate an optimized adjustable guide vane top molded surface and the guide vane. According to the adjustable guid
