The invention provides a site selection method for a wind-solar hybrid power station. The site selection method comprises the following steps: determining a candidate site of the wind-solar hybrid power station; performing micro site selection on a wind generation set; determining the shadow distribution of the wind generation set; determining the mounting position of a photovoltaic array; and verifying and adjusting a site selection result. According to the method, wind energy and solar energy spatial distribution characteristics and the characteristics of wind power plant and photovoltaic power station site selection are considered comprehensively, and wind power plant macro site selection and micro site selection as well as photovoltaic power station site selection and design technology are fused integrally, so that limited land resources and valuable wind energy/solar energy resources are utilized fully, and maximum economic and environmental benefits are achieved.
