| 摘 要： | 本研究首次应用分布式光纤测温技术，监测张掖市临泽县平川段的黑河河床表面温度与河水温度，确定了该时段黑河中游湿地临泽平川段的地表水地下水转换情况。分布式光纤测温系统温度分辨率为0.01℃，采样间距为0.25m，时间间隔为4min。通过对全长550m的河床表面温度与河水温度连续监测，分析该区段温度场动态，发现试验区河段河流受地下水补给，有地下水溢出带。通过河床表面温度与河水温度、环境温度的对比，清楚反映了该河段温度异常带的分布与变化规律，明确了地下水溢出带的位置与地下水溢出强度。

| Abstract: | Groundwater-surface water interactions in the middle reach of Heihe River were investigated by measuring the streambed and stream surface temperatures through fiber-optic distributed temperature sensing(DTS).The DTS system used in this study has a temperature resolution of 0.01℃,sampling interval of 0.25m and temporal interval of 4 minutes.By continuously monitoring the streambed and stream surface temperatures along the river channel through a fiber-optic cable,the 550m long river segment was identified as a groundwater discharge zone.Based on the comparison of observed temperature variations in the atmosphere,streambed and stream surface,the distribution and variation pattern of temperature anomalies were easily identified,thus providing an effective means of studying and revealing the groundwater-surface water exchange along a stream channel. |
