According to the elements of hydrogeological conditions， lithology，stratigraphic thermal physical pa- rameters，construction technology and economic rational elements，the evaluation system of ground source heat pump (GSHP) were established in Baotou plain． The factor weights were determined by using analytic hierar- chy process， and the comprehensive element method was selected to evaluate the region suitability of GSHP sys- tem． The results show that the suitable area is 559． 63 km 2 for utilizing GSHP in the studied area，accounting for 62． 58% of the total area; while the unsuitable area is 334． 60 km 2 ， accounting for 37． 42%． The evaluating results can provide not only a scientific basis for development and utilization rationally of shallow geothermal heat in Baotou，but also offer an important reference to the other areas．
