A heat pump system of soil resource having a function of regulating soil temperature relates to a heat pump system of soil source, solving the problems that the cold and heat loads of the current heat pump system of soil resource are not coordinated in winter and summer, the annual average temperature of the soil is decreased or increased year by year, the system operating efficiency is graduallyreduced and the cannot operate normally. A plurality of heat exchangers of vertical U-shaped underground pipe are connected in parallel and are communicated with an outdoor heat exchange device; a first pipeline is provided with a first and a second pipeline valves; a second pipeline is provided with a fifth, a sixth and a seventh pipeline valves; a fifth pipeline is provided with an eighth and aninth pipeline valves and a second circulating pump; heat pump machine sets are connected with the first and the second pipelines in parallel; a third pipeline between the first and second pipeline valves is provided with a third pipeline valve; and a fourth pipeline between the sixth and the seventh pipeline valves is provided with a first circulating pump and a fourth pipeline valve. The invention is suitable for heating and refrigerating buildings and supplying domestic hot water.
