摘要
HCO-3 concentration, pH, conductivity (EC) and dissolved oxygen are monitored with certain space along the downstream of the Baishuwan Spring—the Baizhi Stream, and a preliminary study on the degasification of the karst water is conducted. The results show that 1) there is a decreasing trend in HCO-3concentration along the flow path; 2) the decreasing speed of HCO-3concentration reflects the speed of degasification; 3) dilution effect of the rain water makes the decreasing trend unobvious; 4) degasification also causes the conductivity (EC) decline along the flow path; and 5) diurnal variation in dissolved oxygen (DO) along the flow path shows that the aquatic organism may have some influences on the degasification.
