The Estimating for the Temperature Gradient and Heat Flow of Julongquan Springs Area in Tianchi Lake,Changbai Mountains

本项研究在野外完成了长白山聚龙泉温泉的测温测流工作;采集了相应的温泉水样,对水样进行了常规分析,获得了K^+、Na^+、Ca^(2+)、Mg^(2+)、SO_4^(2-)、HCO_3^-、SiO_2等组分结果。选取了4个温泉水样作为计算长白山聚龙泉温泉的热储的基本数据;使用玉髓温标公式初步计算了温泉热储的温度;根据Donaldson的管状模型,热流体的对流传输模型和无量刚的温度参数(由热储温度,地表泉口温度和地表平均气温计算)—涌水流量曲线的方法,参考了Rybach(1987)的一组曲线,估算了热水的循环深度(即热储深度);使用地表温度、热储温度和热储深度,由热传导方程得到了长白山聚龙泉温泉地区的地温梯度,估算了该地区的热流。

Writers measured the spring temperature and rate of flow in Julongquan springs of Tianchi Lake, Changbai Mountains. In the field works, some water samples and 6 rock samples are collected. The regular composition of the water samples is analysied, and the heat conductivity of rock samples is measured. The springs thermal water compositions of K^+、 Na^+、 Ca^(2+)、 Mg^(2+)、 SO_4^(2-)、HCP_3^-、SiO_2 are given out. There are four groups parameters of water samples that be selected to calculate thermal reservoir temperatures and depth of Julongquan springs in Changbai Mountains. The SiO_2 temperature meter is used in calculating thermal reservoir temperatures. According to Donaldson's thermal water circulating pipe model and with nondimensional temperature parameters, and according to Rybach's one group curves of nondimensional temperature-circulating depth, we estimate the thermal water circulating depth. With the depth, the temperatures of thermal water reservoir and surface and the conductivity of rock samples, the temperature gradient and heat flow are estimated in Julongquan area of Tianchi Lake, Changbai Mountains.
