摘　　要：通过对金佛山水房泉泉水的水温、pH值、电导率、Ca2+和HCO3-进行监测发现:旅游活动高峰期人流量大会对泉水中离子的变化产生明显的影响.国庆节和五一劳动节期间,降水量和人类活动共同对泉水中离子产生影响,而冰雪节期间,泉水中离子的变化主要受人类活动的影响.Ca2+,HCO3-,SIc和Pco2受水温、降水和人类活动的交替影响,在不同的时间段内,其受影响的程度不一.泉水中CO2的来源与土壤CO2有一定的关系,深层土壤CO2较表层土壤CO2更多地进入泉水,参与了岩溶作用的进行.The variations in temperature, pH, EC, Ca^2＋ and HCO3 of the water of Shuifang Spring in Jinfo Mountains were monitored and the resulting data showed that human activities during the tourism peak period had marked influences on water-ions of Shuifang Spring. During the National Day period （1^st to 7^th of October） and the May Day period （1^st to 7^th of May）, the water ion variation was co-influenced by rainfall and human activities, while during the Snow Festival period （December, January and February）, human activities were the dominant influencing factor. Water temperature, rainfall and human activities alternately influenced Ca^2＋ , HCO3^- , Sic and Pco2 of the spring water, depending on different periods. CO2 in the spring water was associated with soil CO2, and more CO2 from the deep soil profile than from the topsoil seeped into the spring water and participated in the karst process.
