【摘要】 冷热泉在近距离内交替共生的现象较为罕见。在康定市二道桥雅拉河东岸，既存在冷岩溶大泉，在钻孔揭露下又出露热水，其泉口相距不足200 m。为了探讨二道桥地区水样的水化学特征及冷热泉共生系统的成因模式，对区内温泉、冷泉及地表水水样通过水化学手段进行分析。结果表明：二道桥地区的冷泉和热泉具有不同的成因，冷泉的补给来源主要是大气降水以及跑马山融雪补给，经浅循环后出露地表，热水成因是贡嘎山降水及融雪经深循环后与浅层地下水混合后出露于地表，导致温泉温度普遍较低。更多还原

【Abstract】 The phenomenon of hot and cold springs alternating and coexisting within a short distance is relatively rare. On the east bank of the Yala River in Erdaoqiao, Kangding City, a cold karst spring exists alongside hot water exposed through drilling, with their spring orifices separated by less than 200 meters. To investigate the hydrochemical characteristics of water samples and the genetic model of the hot and cold spring coexistence system in the Erdaoqiao area, hydrochemical methods were employed to analyze samples from hot springs, cold springs, and surface water. The results indicate that the cold and hot springs in the Erdaoqiao area have distinct origins. The cold springs are primarily recharged by atmospheric precipitation and snowmelt from Paoma Mountain, emerging at the surface after shallow circulation. In contrast, the hot water originates from precipitation and snowmelt in the Gongga Mountain area, which undergoes deep circulation before mixing with shallow groundwater and discharging at the surface, resulting in generally lower temperatures for the hot springs.更多还原
