| 摘 要： | 金佛山岩溶泉水化学呈现日变化和空间变化的动态特征.在时间上,碧潭泉水化学特征呈现周期性的日变化规律,而水房泉日变化规律不甚明显.由于海拨高程的影响,金佛山岩溶泉水化学变化动态对降雨直接响应的效应不同:在同一时间里,碧潭泉对降水的响应微弱;而水房泉水中的Ca 、Mg2 和HCO3-等离子浓度随降雨而上升,它主要受碳酸盐岩-水-CO2相互作用中的CO2的控制.金佛山岩溶泉水化学特征还受岩性的控制.

| Abstract: | The dynamic state of hydro-chemical characters of karst spring in Jinfo Mt. is presented as diurnal and spatial variation. As for time span, hydro-chemical characters of the Bitang karst Spring is presented as the periodically diurnal variation rule, but for the Shuifang karst Spring its diurral variation rule does not obvious. Owing to the influence of different elevations, the effect is different to the rainfall directly respond due to hydro-chemical characters of karst spring in Jinfu Mt.: In the same time, Bitang Karst Spring respond to rainfall weakly; But the concentration of Ca~+, Mg~(2+) and HCO_3~- et al. of Shuifang karst Spring water rises with rainfall. It mainly controlled by CO_2 concentration in the interaction of carbonate rock-water--CO_2. The hydro-chemical characters of karst spring in Jinfo Mt. are still controlled by lithology. |
