To link regional land use/cover changes with environmental effects, land cover changes are required to reflect vegetation successions, whereas the land cover cl
Based on the studies on diatom, ostracods and magnetism on a core acquired from lacustrine sediments, as well as correlation analysis between concentration of a
Modeling land use scenario changes and its potential impacts on the structure and function of the ecosystem in the typical regions are helpful to understanding
The crystal structure of astrophyllite K2Na(Fe, Mn, Mg, □)7[Ti2(Si 4O12)2|O3](OH, F)4 has been refined. The dimensions of the triclinic unit cell are: a = 0.53
Laser Raman spectrochemical analysis on single inclusion reveals that multi-phase fluid inclusions exist in the Xuebaoding Beryl- Scheelite Vein Deposit. Beside
The influence of pH on the partitioning behavior of REE at the water/particulate interface has been studied experimentally. At the beginning of colloid formatio

We constructed a coupled model for simulating plant photosynthesis and evapotranspiration (CPCEM). In the model, non-rectangular hyperbola is used to simulate l
On the basis of FTIR and Raman spectra studies on hydrous albite glasses, it is found that there exist two water solubility mechanisms in albite melts simultane
