According to the distribution characteristics and occurrence conditions of shallow geothermal energy in Luohe City,the amount of shallow geothermal energy resources and its development and utilization potential were evaluated. Some corresponding suggestions for development and utilization were put forward. The results show that the total area suitable for the development and utilization of shallow geothermal energy is 523.87 km^2,and the total storage capacity of shallow geothermal energy is 318.89×10^12 kJ/℃ . Considering the land use coefficient,the total area comparatively and most suitable for groundwater source heat pump system is 249.12 km^2. The available shallow geothermal energy resources of the groundwater source heat pump system is 74.63×10^12 kJ/a. For this groundwater source heat pump system,the cooling area in summer is 6 397.94×10^4 m^2/a,and heating area in winter is 4 798.45×10^4 m^2/a. The cooling potential of each district in summer is( 23. 52 ~ 26. 09) × 10^4 m^2/km^2,and the heating potential in winter is( 17. 64 ~ 19. 57) × 104 m^2/km^2. The amount of available shallow geothermal energy resources of the buried pipe ground source heat pump system is 211.00×10^12 kJ/a.For this buried pipe ground source heat pump system,the cooling area in summer is 17 157.43×10^4 m^2/a,and heating area in winter is 14 966.10×10^4 m^2/a. The cooling potential of each district in summer is135.12×10^4 m^2/km,and the heating potential in winter is 118.63×10^4 m^2/km^2.
