The utility model relates to a heliostat field for a tower type solar thermal power generation system. The heliostat field comprises receivers, heliostat arrays, a thermodynamic system and an energy transport pipeline, wherein the receivers are used for receiving sunlight reflected by heliostats; the heliostat arrays are used for receiving the sunlight and reflecting the sunlight to the receivers; the peripheral outline of each array is an arc or the combination of the arc and a straight line; the thermodynamic system converts thermal energy into electric energy; and the energy transport pipeline transports the thermal energy generated by the receivers to the thermodynamic system. The heliostat field is arranged on the basis of an optimal mirror field efficiency principle and a maximum thermodynamic system aggregate utility principle, and the peripheral outline of each heliostat array is the arc or the combination of the arc and the straight line.
