我国红层主要分布于长江流域及其以南地区。根据红层发育的地质年代和含膏盐岩层层位不同,可分为西南地区和华南地区红层。根据红层中含可溶盐类矿物的不同,又可分为含膏红层与含盐红层。两种含不同盐类的红层,其地下水化学性质和侵蚀性离子浓度的频率分布特征有明显差别。确定两种含盐红层的侵蚀性离子浓度的频率分布规律,为预测和评价类似地质环境条件下地下水成分特征提供了有意义的参考资料
Red beds in China are mainly distributed in the Yangtze River and its south. According to the geological development of the red beds and the layers of gypsum salt rocks, the red beds can be divided into Southwest China and South China. According to the red layer containing soluble salt minerals different, can be divided into containing red cream and salt red layer. The two red beds with different salts have obvious differences in the frequency distribution characteristics of groundwater chemistry and aggressive ion concentration. Determining the frequency distribution of the erosive ion concentration of two salt-bearing red beds provides a valuable reference for the prediction and evaluation of groundwater components under similar geological conditions
