This manuscript first gives a separate decomposition analysis on the factors that affect regional energy efficiency in Beijing, Tianjin, and Hebei, China, during 2005-12 based on the logarithmic mean divisia index (LMDI) model, and then makes an in-depth investigation on impact factors in the Beijing-Tianjin-Hebei (BTH) region of China. Energy efficiency is decomposed into carbon productivity, carbon...
β-D-glucosidase (βG) gene from Oenococcus oeni SD-2a and 31MBR was cloned, sequenced and analyzed, also intracellular βG of the two strains was further localized. The results showed that βG gene of the two strains was in high homology (> 99%) to reported βG gene, confirming both strains possess βG activity at the molecular level. Intracellular βG of SD-2a is a mainly soluble protein, existing mostly...
Leaf functional traits are indicators of both plant community and ecosystem responses to environmental factors and can thus increase our capacity to understand ecosystem processes and community assembly due to climate change. The variation in leaf functional traits between succession stages in Horqin Sandy Land is caused by soil nutrient content and by intrinsic biological characteristic of species,...
Numerous efforts in investigating the global carbon balance have concluded that the global CO2 budget cannot be balanced unless a ‘‘missing carbon sink’’ is invoked. Until now there have been considerable uncertainties as to the magnitude of the C-sink in different regions and the contributions of aboveground/underground processes. This study is aimed at presenting a first estimate of the gap between...
We based our research on real-time monitoring data for PM2.5 at the Beijing Municipal Environmental Protection Monitoring Center of Haidian Beijing Botanical Garden (a vegetated area), and at Haidian Wanliu (a non-vegetated area). By combining these two data points with the PM2.5 and meteorological data from a separate monitoring station in Beijing Botanical Garden’s forest interior, we analyzed the...
