It is necessary to improve the ecological environment and keep balance of nature reserves that have particularly important function on precious endangered wildlife species conservation. Human activities give rise remarkable changes in land use/land cover (LULC) further an effect landscape eco-environment reserves. This study evaluated risk based LULC Baishuijiang National Nature Reserve according different management zones from 1986 2015. Results showed significant change characteristics...
Abstract Multienzyme cascade approaches for the synthesis of optically pure molecules from simple achiral compounds are desired. Herein, a cofactor self‐sufficient protocol asymmetric amination racemic secondary alcohols to corresponding chiral amines was successfully constructed by employing an alcohol dehydrogenase and newly developed amine dehydrogenase. The compatibility identical dependence two enzymes led ingenious in situ recycling system one‐pot synthesis. artificial redox‐neutral...
Grassland degradation has caused increasingly prominent conflict between ecological environment conservation and socioeconomic development in the Qilian Mountains, China. How to effectively trade-offs synergies is essential achieving sustainable of grassland ecosystem. However, few studies have addressed ecosystem services terms coupling natural system. Therefore, we constructed an index analyzed from perspective "ecological-production-living" functions (EPLFs) spatial-temporal...
The electronic spectrum and eigenstates of a one-dimensional aperiodic Thue-Morse crystal isstudied with an on-site tight-binding model. relation between the constructing elements andthe hierarchical splitting bands into subbands is analysed. are shown to be much more similar those periodic than Fibonacci quasicrystal. We thus claim that link quasicrystal theperiodic crystal, study non-Fibonaccian crystals promising steptowards desired unified theory disordered, systems. Since experimentally...
We study the on-site model of a one-dimensional Fibonacci lattice. It is found that, compared with transfer model, electronic spectrum has different global structure, but same branching rule in following hierarchies. The relationship between numbers constructing elements lattice and eigenstates subbands established. improved Dean method for solving eigenenergies eigenfunctions transfer-matrix are used to examine localization very large samples. Three kinds wave-function behavior (extended,...
Due to climate change and human activities, the eco-environment quality (EEQ) of eco-fragile regions has undergone massive change, especially in Tibet Plateau. The Qilian Mountains (QLM) region is an essential ecological function zone northeastern Plateau, which plays a vital role northwestern China’s eco-environmental balance. However, EEQ changes QLM during 21st century remain poorly understood. In this study, spatiotemporal variations were analyzed from 2000 2020 using remote sensing...
Acoustic band gaps can be opened and tuned by rotating square rods in two-dimensional liquid sonic crystals. For the systems of mercury with cross section a water host, width lowest increases as rotation angle increases. But opposite results are found for inverse mercury, where narrow an increase angle. This gap-tuning effect becomes more evident filling fraction increase. Such should open up new way designing acoustic phononic
Point defect modes of acoustic wave in two-dimensional square arrays water rods a mercury host were studied. The defects are created by three kinds geometry, namely, defect, circular and rectangular respectively. results show that for both the only related to filling fraction ${F}_{d}$, but not with geometry (square or circular), as well orientations defect. For could be tuned changing ratio edge width moreover, double degenerate one will split into two nondegenerate when widths...
