　　以梧州水文站监测水点为对象，定期对水体中HCO－3浓度、Ca 2＋质量浓度、电导率、pH值等水质指标进行测定、分析。结果表明：西江梧州水文站监测的水样中的HCO－3浓度非汛期高，汛期低；水中的HCO－3浓度、电导率、Ca 2＋质量浓度在汛期呈递减趋势，而在非汛期则呈递增趋势；汛期和非汛期pH值均呈递增的趋势。梧州水文站监测水点全年碳汇量（以CO2计）为5707.59×106 kg；汛期碳汇量为3324.63×106 kg，占全年碳汇量的58.25％；非汛期碳汇量为2382.96×106 kg，占全年碳汇量的41.75％。

Water quality indices including the HCO-3 concentration, Ca 2+mass concentration, pH value, and electrical conductivity (EC) in the water from the monitoring site at the Wuzhou Hydrological Station on the Xijiang River were monitored.The results show that the HCO-3 concentration in the non-flood season was higher than that in the flood season.The HCO-3 concentration, Ca 2+mass concentration, and electrical conductivity (EC) showed a decreasing trend in the flood season and an increasing trend in the non-flood season.The pH value showed an increasing trend both in the flood season and in the non-flood season.The total annual karst carbon sink amount at the monitoring site was 5707.59×10 6 Kg.The karst carbon sink amount in the flood season was 3324.63×10 6 Kg, accounting for 58.25%of the annual amount.The karst carbon sink amount in the non-flood season was 2382.96 ×106 Kg, accounting for 41.75%of the annual amount.
