摘要
基于对泉水水化学特征(pH、t、Ca2+、Mg2+、K+、Na+、Cl-、HCO3-、SO24-)的观测,探讨了云南维西孔隙水、浅部裂隙水、深部构造裂隙水、花岗岩与灰岩接触带水、花岗岩与第四系堆积物接触带水风化碳汇规律及影响因素。并在全国花岗岩分区的基础上,选取云南维西、广西新寨、湖南郴州和北京怀柔为代表点进行区域对比,并初步计算了全国花岗岩碳汇量。
Based on the analysis of some hydro-chemical indexes of springs, including pH, t, Ca^2＋, Mg^2＋, K^＋, Na^＋, HCO3^-, Cl^- and SO4^2-, this paper discussed the carbon sink and its influencing factors of granite pore water, shallow seated fracture water, deep seated tectonic fracture water, water in the interface of granite and carbonate rock and water in the interface of granite and Quaternary deposit. Moreover, on the basis of granitic division of China, Weixi of Yunnan, Xinzhai of Guangxi, Chenzhou of Hunan and Huairou of Beijing are selected as typical granite areas for regional correlation, and the total carbon sink in China caused by granite weathering was calculated.
