The utility model provides a terrestrial heat heating system for gradient utilization after treatment. The terrestrial heat heating system comprises a pipeline, a terrestrial heat pumping well, a stepped plate heat exchanger, a stepped ground source heat pump unit and a terrestrial heat recharge well, the stepped plate heat exchanger is formed by arranging a plurality of plate heat exchangers in a stepped manner; the stepped ground source heat pump unit is formed by arranging a plurality of ground source heat pump units in a stepped manner; the terrestrial heat pumping well is connected to a radiator end user and a floor heating end user through pipelines by virtue of the stepped plate heat exchanger and the stepped ground source heat pump unit, and flows back to the terrestrial heat recharge well; a cyclone desander is further arranged at the water outlet position of the geothermal pumping well in a matched mode. According to the heating system which integrates the impurity removal function and is designed i
