常温层温度及深度是浅层地温场的重要指标,工程实践中常用常温层温度来代表地下岩土体原始温度。研究表明常温层温度与年均气温和大地热流密度密切相关,浅层地温能是在太阳能照射和地心热产生的大地热流的综合作用下,存在于地下近表层数百米内的土壤、砂岩和地下水里的低温地热能。据常温层温度特征,将我国浅层地温能分为tH≧15℃、tH=10～15℃和tH≦10℃3种类型。

The temperature and thickness of the room temperature zone are the important indicators of the shallow geothermal field. In engineering practice, the temperature of the room temperature zone is commonly used as the original temperature of the underground rock and soil. It shows that the temperature of the room temperature zone is closely related to the annual average air temperature and the terrestrial heat flow density. The shallow geothermal energy is generated under the combined effect of the solar radiation heat and the terrestrial heat flow, and it belongs to the low-temperature geothermal energy occurring in the soils, sandstones, groundwater within a few hundred meters of near-surface. According to temperature characteristics of the room temperature zone, China shallow geothermal energy is divided into three types（ tH≥15℃, tH =10-15℃ and tH≤ 10℃）.
