摘要
为探寻西苕溪地表、地下水体的来源和补排关系,对西苕溪流域丰水期和平水期的地表、地下水进行了氢氧同位素(δD和δ18O)组成分析,并结合水体的水化学参数,推断其来源和补排关系。结果表明:西苕溪流域地表、地下水体主要接受降雨补给,在上游山区中的泉水运移过程较为缓慢,上游地表水与地下水补排关系不明显;中游丘陵地区地表、地下水体相互联系紧密,具体补排关系为3号、4号、6号样点处地表水接受地下水补给,其余样点处为地表水补给地下水;下游农田密集区地下水接受河水补给较少。
To get clear where the water in Xitiaoxi river basin came from and the relationships between surface and ground water, samples were collected and analyzed in both normal season and wet season. By comprehensive consideration of hydro - chemistry and characteristic of D：H and 18^O：16^O, the following conclusions have been obtained ： 1. The surface and ground water in Xitiaoxi river basin were mainly supplied by precipitation. 2. Groundwater under mountain area moved slowly, the influence it may cause to the lower stream is inestimable. 3. The surface water and ground water have few interaction in the Laoshikan branch （marked by 11 and 2） and frequent interaction in other places. The specific relationship of groundwater supplying surface water was found at sample 3, 4, 6 ; and reversed situation in other places.
