Unreasonable exploitation of groundwater resources in the Kongque River region has led to a decline in the groundwater table, groundwater salinization, and other geo-environmental problems. Therefore, this study supplements the studies on soil water and salt transport in the Kongque River region, and provides a new method for the prevention of groundwater salinization in arid and semiarid regions...
This study takes the Southern antimony smelting slag depot in Xikuangshan (XKS) Sb mine in the city of Lengshuijiang, Hunan, China, as the research object and explores the release law of Sb, As, and Hg in smelting slag under different pH-value simulated acid rain by a semi-dynamic leaching experiment of simulating the local rain. The results show that the leachate pH value is positively correlated...
In order to evaluate the effects of different slope lengths (1, 2, 3, 4, and 5 m) and different vegetation coverage ratios (20%, 45%, 60%, and 90%) on the mechanisms of nutrient loss and runoff producing processes, we have conducted 14 simulated rainfall experiments. The results show that N and P loss are decided by the concentration and the runoff volume, but when the amounts of N and P in topsoil...
