The CO₂ emissions from China’s coal consumption account for 14.3% of the world’s CO₂ emissions. The taxation of China’s coal industry affects the progress of world emissions reduction to some extent. This paper establishes six countermeasure scenarios with different tax systems considering carbon tax and indirect tax, then constructs a dynamic recursive computable general equilibrium model to simulate...
The Beijing-Tianjin-Hebei Region (BTH) as a national strategic highland attracts attention with its haze problem. In particular, Hebei is a major emitter of carbon emissions in BTH. The establishment of the Xiong’an New District in Hebei, known as the “Millennium plan,” faces complex and diverse development in the future, so the carbon emission prediction and influence mechanism are of great significance...
Carbonaceous greenhouse gases (i.e., CO₂, CH₄ ) have often reported to be emitted from the surfaces of reservoirs, while other non-carbonaceous greenhouse gases are not available to many reservoirs. In this study, the spatiotemporal variability of N₂O emissions from Xin’anjiang Reservoir was investigated at the different regions over a 13-month period using the method of the static floating chambers...
Nowadays, with the depletion of fossil energy and deterioration of environmental quality, solar energy is perceived to be a renewable and clean energy. While developing rapidly all over the world, solar energy is also faced with many challenges resulting from its inherent properties. In order to reduce the impact on the grid and facilitate scheduling, it is a growing problem to build a feasible model...
In this study, tri-butyl-phosphate (TBP)-kerosene is used as the extraction solvent to remove phenols from coal gasification wastewater, and the complex mechanism of the extraction is investigated. An effect experiment is conducted to determine the complex structures, the enthalpy change of reaction, and the effect of extraction solvent concentration and temperature on the distribution coefficient...
Located northeast of Yuxi City, Yunnan Province, China, the Fuxian Lake Basin is not only a famous scenic area, but also an ecological and environmental protection zone. The basin is a plateau mountainous lake region that has key ecosystem vulnerability and sensitivity. A dynamic evaluation of ecological vulnerability is important for assessing the ecological environment of a region, which is significant...
Thallium (Tl) is a typical trace metal of extreme high toxicity. As a concomitant element, Tl is widely found in various sulfide minerals and K-containing rock minerals. The outburst of Tl pollution in drinking water sources of the northern branch of the Pearl River in China as reported in 2010 has greatly aroused public concerns about Tl pollution in China. Apart from typical sources of Tl pollution...
Water inrush is one of the typical geological hazards in the construction of high-risk tunnels, and has caused severe losses. To predict water inrush accurately, a novel model was put forward for karst tunnels in the present study. The ideal point method coupled with the analytic hierarchy process method (AHP) was applied for risk assessment of water inrush. First, the ideal point method was introduced...
