研究天然水中水的化学组份与自然地理环境要素之间的内在联系,及其在时间与空间中的变化规律是天然水化学的任务。当前社会主义经济建设中的水利建设,河川改造,工农业生产,环境评价等,经常与水化学的研究密切相联,因而水化学的研究有它重要的现实意义。华南,系指我国秦岭淮河一线以南,包括长江中下游、四川盆地、云贵高原、江汉平原、湘、桂、赣及东南浙、闽、粤诸省,
It is the task of natural water chemistry to study the inherent relationship between the chemical composition of natural water and the elements of natural geographical environment and its variation in time and space. In the current socialist economic construction, water conservancy construction, river reconstruction, industrial and agricultural production, environmental assessment and so on are often closely linked with water chemistry research. Therefore, water chemistry research has its important practical significance. South China refers to the south of the Huaihe River in Qinling, including the middle and lower reaches of the Yangtze River, the Sichuan Basin, the Yunnan-Guizhou Plateau, Jianghan Plain, Hunan, Guangxi, Jiangxi and southeast Zhejiang, Fujian and Guangdong provinces,
