摘要(Abstract)：

由于流域人类活动对水资源的消耗,使河流下游径流量降低,因此研究流域化学风化时必须考虑耗水量的贡献。本文根据课题组2007年黄河流域的化学风化数据,结合流域耗水量,重新估算了黄河流域硅酸盐风化大气CO2的消耗量和消耗率,分别为19.92×109mol.a-1和26.50×103mol.km-2.a-1。黄河流域耗水量对硅酸盐风化消耗大气CO2的贡献已经达到了入海径流量所表征的数量级。针对黄河流域岩石分布类型复杂的特点,作者提出了分段考虑耗水量的计算方法,定量给出了黄河上、中、下游硅酸盐风化CO2的消耗量和消耗率。黄河流域硅酸盐风化CO2消耗率上游>中游>下游,消耗量中游>上游>下游。上、中游硅酸盐风化CO2的消耗量分别为下游的33和37倍左右。

关键词(KeyWords)： 黄河;硅酸盐风化;耗水量;CO2消耗率
