| 英文摘要 | The study focuses on the chemical and trace element compositions of the dissolved load in the upper Han River, the water source area of the Middle Route of China's South-to-North Water Transfer Project. Water samples were collected in the high flow period and analyzed for cations by Inductively Coupled Plasma Atomic Emission Spectrometer and anions by ionic chromatography respectively, in order to understand the contributions of anthropogenic activities and rock weathering to river solutes, as well as the associated CO(2) consumption in the carbonate-dominated basin. The river waters have a mean T(z)(+) of 2674 mu eq/l ranging from 1034.3 to 4611.6 mu eq/l, which is significantly higher than that of the global river waters. Calcium and HCO(3)(-), followed by Mg(2+) and SO(4)(2-). dominate the chemical composition of major species in the basin. There are three major reservoirs (carbonates. silicates and agriculture/urban effluents) contributing to the dissolved load in the river. Chemical weathering rate is approximately 53.1 t/km(2)/yr with respective carbonate and silicate weathering rates of 47.5 t/km(2)/yr (19.8 mm/kyr) and 5.6 t/km(2)/yr (2.1 mm/kyr). The CO(2) consumption is estimated to be 64.69x10(9) mol/yr and 9.69x10(9) mol/yr by carbonate and silicate weathering, respectively. The contribution of the anthropogenic inputs to the dissolved load is estimated to be 16.7%, demonstrating the strong impacts of human activities on water chemistry. (c) 2009 Elsevier B.V.
