地下水科学与工程试验基地地温变化特征

摘要

Groundwater Science and Engineering test base is Ministry of Land Natural Resources field base. The automatic weather station is a collection of small regional meteorological, data. Based on the ground temperature from 2007 to 2011, the results indicated that the shallow ground temperature has obvious diurnal variation, the deep ground temperature change is not obvious; 0 ?320 cm layer has obvious variation, the appearing time of the highest level (low) value decreased with soil depth increasing; temperature in summer and winter, spring and autumn show opposite trends.%地下水工程与试验基地是国土资源部野外科学观测研究基地,其自动气象站采集小区域的气象数据.选取2007-2011年自动观测地温资料进行统计分析,结果表明浅层地温具有明显的日变化,深层地温变化则不明显；0～320 cm整层地温均具有明显的月变化,各层次最高(低)值的出现时间均随土壤深度的递增而推迟；夏季与冬季、春季与秋季地温垂直分布呈现完全相反的变化趋势.
