摘　　要：基于五龙河流域上游地区开展的1∶5万水文地质调查工作成果,分析流域水文地质特征,研究其富水机理和规律,重点总结岩脉导水型、断裂交汇式导水型及岩浆岩多期构造运动形成的典型复合型富水机理、地下水年内及年际动态变化及含水介质发育特征,结果表明:研究区地下水类型分为松散岩类孔隙水、碎屑岩类孔隙裂隙水、碳酸盐岩类裂隙岩溶水及岩浆岩变质岩类裂隙水四大类,地下水的循环运动及富水性特征受地形地貌、含水介质、地质构造等因素影响,不同类型、不同区域地下水运动方式及富水性存在明显差异;地下水水位呈现“下降-上升-下降-上升”季节性、周期性的变化特征,地下水水位和降雨量响应明显,枯水期水位降幅较大,变幅3~7 m,丰水期水位回升迅速;研究区含水介质发育特征以垂向构造裂隙为主,裂隙率与含水层段明显吻合,裂隙率越高,储水空间愈大,富水性愈强;岩脉导水型、断裂交汇式导水型和岩浆岩多期构造运动形成复合型三类富水模式,圈定小水岔、刘家窑、王家山后、董家-桑行-怀古庄4处富水块段。研究结果为区域地下水资源合理开发利用及类似地区找水定井提供水文地质支撑。Based on the results of the 1:50,000 hydro-geological survey carried out in the upstream area of the Wulong River Basin,the hydro-geological characteristics of the basin were analysed and the water-rich mechanism and rule were studied,with emphasis on the summary of the typical composite water-rich mechanism formed by rock vein-conducted,fracture-intersection-conducted and multi-phase tectonic movement of magma rock,the intra-annual and inter-annual dynamic changes of groundwater and the characteristics of water-bearing medium development:the groundwater types in the study area are divided into four categories:loose rock pore water,clastic rock pore fracture water,carbonate rock fracture karst water and Igneous metamorphic rock-like fissure water.The circulation movement and water-richness characteristics of groundwater are influenced by topography,water-bearing media,geological structure and other factors,and there are obvious differences in groundwater movement and water-richness between different types and regions;the groundwater level shows a seasonal and cyclical change characteristic of“fall-rise-fall-rise”,the groundwater level and rainfall response is obvious,the water level drops more during the dry period,with a variation of 3~7 m,and the water level rises rapidly during the rich period;the development characteristics of water-bearing media in the study area are dominated by vertical tectonic fissures,and the fissure rate obviously coincides with the water-bearing section;the higher the fissure rate,the larger the water storage space and the stronger the water-richness;three types of water-rich patterns are identified,namely,the rock-vein-conducting type,the fracture-intersection-type water-conducting type and the composite type formed by the multi-phase tectonic movement of magmatic rocks,and four water-rich blocks are identified,namely,Xiaoshuixi,Liujiayao,Wangjiashanhou and Dongjia-Sangxing-Huaiguzhuang.The results of the study provide hydro-geological support for the rational exploitation of reg
