【摘要】 乌蒙山区划跨云南、贵州、四川三省,是国家新一轮扶贫开发攻坚战主战场之一,五角堡背斜位于乌蒙山区中部,分布于绥江县五角堡至屏山县楼东一带,背斜周边共出露天然泉点45个,幸福泉位于五角堡背斜北西翼,距离核部2km,枯水季流量141L/s,丰水季流量822L/s,为新滩镇供水水源地。根据前人调查,此泉的成因机理研究主要有两种截然不同的理论,一种为"上升泉理论",一种为"下降泉理论",针对这两种理论,以现场调查、示踪试验及地球物理勘探为依据,对幸福泉成因机理进行深入分析并提出自己的观点,认为幸福泉为岩溶裂隙上升泉,为此后同类富水性背斜泉群的研究及该地区地下水资源的合理开发利用提供科学依据。更多还原

【Abstract】 Wumeng Mountain stretch across Yunnan,Guizhou and Sichuan provinces.It is one of the battlegrounds for the new round of poverty alleviation in China.The Wujiaobao anticline is located in the middle of Wumeng Mountain,and distributed in the area from the Wujiaobao of Suijiang County to Loudong of Pingshan County.There are 45 natural.springs exposed in the periphery of the anticline.The Xingfu Spring is the water supply source of Xintan town that 2 km away from the core,which is located in the northwestern wing of the anticline of Wujiaobao,and the seasonal flow is 141 L/s and 822 L/s in the low water season and in the abundant water season respectively.According to the previous investigations,there are mainly.two different theories on the genesis mechanism of the spring,one is the theory of "rising springs" and the other is the theory of "falling springs".According to the above theories,this paper made an in-depth analysis of the genesis mechanism of the Xingfu Spring and put forward its own point of view based on field investigation,tracer test and geophysical prospecting.It will provide a scientific basis for the research on the same type of water-bearing anticline springs and the rational exploitation and utilization of groundwater resources in the area.更多还原
