摘　　要：西山乳泉是广西桂平市的著名旅游景点,因其优良的水质和间歇性"喷乳"的神秘色彩而闻名。本文主要从自然地理、地形地貌、地质构造、水化学特征和环境同位素等方面研究了西山乳泉的水文地质特征和补给来源,以及形成"喷乳"奇观的可能原因。研究结果表明:西山乳泉为一侵蚀下降泉,出露于花岗岩崩塌体及坡积物含水层中;西山乳泉"喷乳"的原因与当地茂密的植被、独特的花岗岩构造、温暖湿润的气候等地理环境、地质条件和气候条件等密切相关。Ru Spring is a famous tourist attraction,known for its excellent water quality and intermittent ＂spraying milk＂ mystery.This paper analyzes the hydrological characteristics,recharge sources and possible causes of ＂spraying milk＂ of Ru Spring from the physical geography,topography and structure,water chemical characteristics,environmental isotopes and so on.The conclusion is that Ru Spring is an erosion descending spring,and is formed in the aquifer of granite colluvial deposit and slope sediments.The ＂spraying milk＂ phenomenon has a close relationship with the dense vegetation,unique granite structure,warm and humid climate,geographical environment and geological conditions.
