摘　　要：通过对已发布的中国大陆地区共1451个地温测点实测数据的整理分析,基于ArcGIS平台建立了地温测点信息数据库,可输入任意地理坐标,查询该坐标点指定范围内的测点信息。在ArcGIS平台利用已有测点数据,应用普通克里金(Kriging)插值法在整个中国大陆地区进行空间插值,得到100m空间分辨率的大地热流预测值与深度1000m以内的地温梯度预测值,并将预测值补充到数据库中,形成了完整的地温基础数据库,可用于查询任意地点的热流值与深度1000m以内的地温梯度值。探讨了影响地温分布的主要因素,为修正地温基础数据提供参考。该数据库可为地热利用系统及地下工程热湿环境控制系统设计提供基础数据支撑。Through sorting out and analysing the measured data of 1451 geothermal measuring points published in the Chinese mainland,an information database of geothermal measuring points is established based on ArcGIS platform.Any geographical coordinates can be input to query the information of measuring points within the specified range of the coordinate points.Using the existing measuring point data on ArcGIS platform,the general Kriging interpolation is applied to carry out spatial interpolation in the whole Chinese mainland area to obtain the geothermal heat flow prediction values with a spatial resolution of 100 m and the geothermal gradient prediction values within 1000 m.The prediction values are added to the database to form a complete geothermal basic database which can be used to query the heat flow values at any place and the geothermal gradient values within 1000 m.The main factors affecting the geothermal distribution are discussed,providing a reference for correcting the geothermal basic data.This database can provide basic data support for the design of geothermal utilization systems and underground engineering hot and humid environment control systems.
