怀来地区多层位地温变化研究

利用MAPSIS、MapInfo、SPSS等软件，对怀来地区不同层位2012～2015年的地温观测数据进行分析。根据井中东西南北4个方向的温度传感器数据，可以得到附近热水管道的大致方位，总体来说4个方向的地温变化趋势相近。不同深度的地温数据结合相关系数分析表明，探测井3.2 m深度以下地层的温度基本不受天气影响，只有缓慢的年变化；5 m深处的地温曲线较为平稳，考虑到经济性与方便性，最终选取5 m为地温观测深度。

Study on Multi-Depth Geotemperature Changes in Huailai

Based on geothermal observation data from 2012 to 2015 in different strata in Huailai, combined with MAPSIS, MapInfo, SPSS and other software to analyze the data, several conclusions can be drawn. Analyzing the east, west, south, north data of the temperature detectors in wells, we can get the approximate position of the hot water pipe nearby. In general, the changing trends of geotemperature in four directions are almost similar. According to the figure of geothermal curve of the multiple depth, combined with the analysis tables, the conclusion could be drawn that under 3.2 meter, the geotemperature near the wells is not affected by the weather on the whole, with only slow annual change. The geothermal curve of 5.0 meter deep is more stable. Considering economy and convenience, the best depth of geothermal observation is 5 meter.
