    Abstract
  • Daily changes of dissolved inorganic carbon in river mainly are controlled by carbonate back-precipitation，aquatic photosynthesis and CO2 degassing at water-air interface. Dissolved inorganic carbon uptake by aquatic photosynthesis is a part of karst carbon sink，and the size of degassing proportion values acts as the determinant factor for carbon sink stability. To analysis of the loss of bicarbonate caused by aquatic photosynthesis and relevant calcite precipitation processes，high resolution monitoring for water chemistry and high-frequency water sampling in daily scale were conducted in a 15 km-long section between Shengli and Guanyan in middle course of Lijiang River. The results showed that the flux of photosynthesis uptake of dissolved inorganic carbon in monitoring section is about 859 kgC?d-1. DIC removal value by photosynthesis and calcite precipitation value are 2.06 t?（d?km）-1 and 0.78 t?（d?km）-1， respectively. CO2 degassing value accounts for 28.4 % of total carbon removal，namely，approximately 70% of carbon removal was converted into organic carbon and precipitated in riverbed in form of calcite，thus constitute a part of karst carbon sink. DIC removal accounts for about 6.0 % of total input，in which 1.7 % returned to the atmosphere in the form of CO2，indicating DIC uptake by aquatic photosynthesis during the summer low water level can restrain CO2 degassing process in air-water interface effectively during the day time. The low degassing proportion suggested that DIC in water body of Lijiang River is relatively stable.
