Over the last 5 decades, runoff from the upstream area of the Yongding River basin has greatly decreased because of changes in the climate and in the intensity of human activities. The Mann-Kendall rank correlation trend test, cumulative anomaly method, and double mass curve of precipitation and runoff were applied to analyse the hydrological sequence trends and altered features in the upstream area...
Emissions trading schemes (ETS) have been treated as a cost-effective mitigation measure to effectively control carbon emissions. Industrial carbon emission quota allocation is prior to the implementation of ETS. This study takes industrial sectors in China as a case to apportion carbon emission quotas. An informational entropy and multiple-factor mixed weighting allocation model (IEMMA) was established...
Radioactivity and heavy metal toxicity of multi-metal deposits coexisting with the element uranium (U) could have long-term adverse impacts on soil biological processes and the health of soil ecosystems. Soil enzyme activities are considered bioindicators for assessing soil health. An experiment was designed to investigate invertase and ß-glucosidase activity in multi-metal deposits. Radioactivity...
This paper identifies the driving forces of CO₂ emissions from 1990 to 2014 in Xinjiang’s transport sector based on the logarithmic mean divisia index (LMDI) method. Then we introduce the decoupling index to further quantitatively analyze the delinking indicators on the transport sector’s growth and environmental pressures. The results indicate that: 1) CO₂ emissions increased significantly with an...
