Water inrush during the excavation of mines or mining is one of the great challenges in underground engineering work in China. To prevent and/or mitigate water inrush, natural sedimentary rocks with low-permeability, which include the mudstone and sandstone found in underground excavations, are exceptional materials for geological barriers. The aim of this work is to therefore investigate the hydraulic...
Based on the data of annual average values of PM₁₀ concentrations in China, this study empirically investigates the spatial autocorrelation of haze pollution in China and the mutual influence of energy consumption and foreign direct investment on haze pollution in China from 2004 to 2014 using the spatial econometric method. Moran’s I values are all above 0 during the 10 years, which indicates that...
Long-term changes (2003-14) of water temperature, DO, pH, TN, NH4-N, TP, and CODMn were examined at eight sampling stations along the Liujiang River. Water quality parameters showed considerable spatial and temporal variability. Annual averages of those parameters were 22.1ºC, 7.8 mg/L, 7.58, 1.35 mg/L, 0.27 mg/L, 0.06 mg/L, and 1.7 mg/L, respectively. An increasing trend for TN/TP and a decreasing...
The aim of our study was to investigate the effects of some main factors, temperature, moisture condition, and organic matter input on soil organic carbon mineralization based on the method of an incubation experiment carried out at Hongze Lake wetland in Jiangsu province of China. The result showed that mineralization rate dynamics of soil organic carbon conformed to the logarithmic equation. Temperature...
