| 摘 要： | 【研究目的】揭示武汉北部新城地表水、地下水的氢氧稳定同位素特征及其相互作用。【研究方法】2019年,采集、测定了降水样7件、河水样6件、水库样14件、民井样98件、泉水样3件和钻孔样11件,并收集到武汉站1986—1998年的监测数据50件,以空间分析和流域分析为基础,氢氧稳定同位素分析为手段。【研究结果】（1）武汉降水氢氧同位素随季节变化,并表现出“降雨效应”明显、“温度效应”不明显的特点;（2）地表水在枯水期受到强烈的蒸散发,表现出一定的“地貌效应”与“干支流效应”的特征;（3）民井、泉和钻孔等地下水均源于大气降水,表现出“含水层埋深效应”与“山区平原效应”的特点;（4）枯水期,界河流域中界河获得了上游水库和地下水的补给,夏家寺水库流域中夏家寺水库得到了地下水补给。【结论】氢氧同位素能显著提高武汉北部新城地表水-地下水相互转换规律的认识。创新点：利用各类水体氢氧同位素组成及空间分布特征,揭示了武汉北部新城降水、地表水和地下水相互转换的规律

| Abstract: | This paper is the result of hydrogeological survey engineering.Object]Reveal the characteristics and interaction of D and 18O between surface water and groundwater in the northern new town of Wuhan,Methods]7 precipitation samples, 6 river samples, 14 reservoir samples, 98 minjing samples, 3 spring samples and 11 borehole samples were collected and measured in 2019, what'' s more, 50 monitoring data of Wuhan station from 1986 to 1998 were collected. The research methods of D and 18O spatial analysis and watershed analysis are carried out in this paper.Results](1) The D and 18O isotopes of precipitation in Wuhan vary with seasons, and the negative correlation between isotopic value and precipitation indicates "rainfall effect", but the no correlation between isotopic value and temperature indicates "no temperature effect". (2) Due to strong evapotransporation, the surface water shows the certain correlation between isotopic value and geomorphic types, and the main stream is enriched in stable isotopic, while the tributaries is depleted; (3) Groundwater such as wells, springs and boreholes are all derived from atmospheric precipitation, and the stable isotopes value of groundwater is related to the buried depth and geomorphic type; (4) During the dry season, the Jiehe River is recharged by upstream reservoir and underground water in the Jiehe basin, and the XiaJiasi reservoir is recharged by underground water in the XiaJiasi reservoir basin.Conclusion]D and 18O can significantly improve the understanding of the conversion relationship between surface water and groundwater in the northern new town of Wuhan.Highlights: Based on the D and 18O composition and spatial distribution characteristics, the mutual transformation law of precipitation, surface water and groundwater in the northern new town of Wuhan is revealed. |
