Abstract The chemical evolution of groundwater has received close attention from hydro-geologists. Northwest China largely consists of arid and semi-arid regions, where surface water and groundwater frequently exchange with each other, and where the mixing and water–rock interactions significantly affect the direction of water quality evolution. Based on experimental simulation, this paper investigates the interactions among the Yellow River water, groundwater and rocks in Yinchuan. The study found that when groundwater is mixed with the Yellow River water, the Yellow River water has a certain dilution effect on the hydro-chemical composition of groundwater; however, this effect is not simply diluted by proportion for no reaction between irons, but a portion of calcium, sulfur, and carbonate form precipitates. After mixing of the Yellow River water, groundwater and rocks, the pH increased, and the carbon dioxide system reached equilibrium again. In addition, CO32− was produced. While Na+ increase was mainly due to dissolution, SO42− decrease was because of precipitation. The precipitation or dissolution of Ca2+, Mg2+, and CO32− mainly depended on the mixing ratio between groundwater and river water, which suggested the reversible behavior of the dissolution-precipitation of carbonate minerals.

This paper analyzes the circumstance of the sharp cutoff of water and sediment in He-Long reach recently, discusses the cause of the change of water and sediment. The study shows that, the change of underling surface and the rainfall without runoff are the primary reason for the sharp cutoff of water and sediment, if the rainfall condition changes, especially under the rainstorm which in the large area, with high strength and last for long time, the accumulated and secluded sediments could make the sediment yield increase sharply, the circumstance of sharp cutoff of water and sediment would change.

This article takes an ecocritical approach that challenges the urban imaginary informing the notion of place and the identity of inhabitants in mainland China. It explores an alternative mode of imagination, symbolized by the flow and instability of water. The work of documentary filmmaker Dong Jun and renowned writer Su Tong can be seen as attempts to evaluate and revisit history and memories through a reconnection with water, whether it be the Yellow River in Dong Jun’s Flood or the river/water world in Su Tong’s The Boat to Redemption. Instead of commenting directly on the destruction of nature as a result of human development and cultural upheaval, both works use water as an indirect means to raise these issues.
