With the implementation of ecological projects such as the Grain-for-Green Project, rocky desertification control and comprehensive control of soil and water loss for sloping farmland, ecological environment of karst mountainous areas in southwest China has been improved significantly, but soil and water loss of sloping farmland is still an important ecological and environmental problem in this region...
The Qinghai-Tibet Plateau is a more sensitive area of climate change and fragile zone of ecological environment. Qinghai Province is an important component of the Qinghai-Tibet Plateau, and the study of streamflow in the province is of great significance for understanding the situation of water resources. Based on hydrological data of hydrological stations in Qinghai, the spatiotemporal variations...
Scoria, a natural silicate mineral, was used for the adsorption removal of antibiotics from water. The kinetics of adsorption were studied during the experiment and the results showed that the adsorption of three antibiotics (sulfathiazole (ST), sulfamethazine (SM2), and sulfamethoxazole (SMX)) by scoria fit the Freundlich isotherm well. Additionally, batch experiment data were fitted using pseudo...
Deteriorating water quality in urban areas has drawn wide interest in China. In our study, water quality was monitored monthly during December 2009-November 2011 from 16 sites located in a trans-urban river. The spatial pattern showed that the concentrations of EC, Ca²⁺, Mg²⁺, BOD₅, CODcr, TP, and NH₄⁺-N were higher midstream and downstream than upstream, while measured pH and DO upstream were higher...
