This paper reviews the progress in the research on river water chemistry in China. It includes three parts: 1) the development of river water quality monitoring in China (at present, there exist three water quality monitoring networks in China: near 3000 water quality monitoring stations under the Ministry of Water Resources, several thousands water quality monitoring sites under the State Environmental Protection Administration and four sites under the China’s GEMS/Water Program); 2) progress in the research on chemical characteristics of river water chemistry in China and their geographical roles on natio wide and region wide scales; and 3) progress in the research on river quality changes in the last 40 years (the long term monitoring data reveals that the water quality of the Changjiang River has acidification trend, the Songhuajiang River had alkalization trend, and the Huanghe River has concentration trend in the last 4 decades).展开更多
文摘River water resource is the most important component of water resources in China. This paper reviews the progress in the research on river water chemistry in China. It includes three parts: 1) the development of river water quality monitoring in China (at present, there exist three water quality monitoring networks in China: near 3000 water quality monitoring stations under the Ministry of Water Resources, several thousands water quality monitoring sites under the State Environmental Protection Administration and four sites under the China’s GEMS/Water Program); 2) progress in the research on chemical characteristics of river water chemistry in China and their geographical roles on natio wide and region wide scales; and 3) progress in the research on river quality changes in the last 40 years (the long term monitoring data reveals that the water quality of the Changjiang River has acidification trend, the Songhuajiang River had alkalization trend, and the Huanghe River has concentration trend in the last 4 decades).
