摘要:

redundant factors were excluded from the initial fourteen landslide causal factors via factor correlation analysisTo determine the most effective causal factors, landslide susceptibility evaluations were performed basedon four cases with different combinations of factors ("cases").In the analysis, 465 (70%) landslide locations were randomly selected for model training, and 200 (30%The ROC curve analysis showed that the machine learning model performed better than the other three models

摘要:

on sustainability of water resources and ecology in the complex karst critical zone, we illustrated functionsof the hydro-geochemical analysis on hydrology from the aspects of connection and interaction amonghydrology-vegetation-soils/rock fractures along the karst subsurface profile.In this paper, the application of the hydro-geochemical analysis on the above aspects in the karst areas

摘要:

Studies have examined carbon storage density (CSD) distribution in temperate forests.A spatial heterogeneity analysis by semi-variogram revealed that CSD varied at less than the mesoscaleGlobal spatial autocorrelation analysis indicated that CSD was clustered at the village level (at 5%A geographically weighted regression model showed different impacts on the different areas for each determinantBased on these results, we propose certain measures to increase forest carbon storage, including increasing

摘要:

We present a systematic re-assessment on how the doped nickel may affect the iron isotope analysis inThus, caution is required when adding Ni to the analyte Fe solutions before analysis.

摘要:

estimation model were established on the basis of hyperspectral techniques, and their applicability in differentBoth models achieved optimal stability and reliability when AB was used as an independent variable.Both models could be applied to different soil types; however, MLR had better applicability comparedThe PCR model that distinguished different soil types had better reliability than one that did not.

摘要:

alluvial aquifer of Boumerzoug-El khroub valley has been processed simultaneously with Multivariate analysisCluster analysis identified three main water types based on the major ion contents, where mineralizationby FA/PCA, which demonstrated that groundwater quality is influenced by geochemical processes (water–rock

摘要:

The sampling campaign in 2019 based on 13 physicochemical parameters was carried out on the water fromPrincipal component analysis and hierarchical cluster analysis (HCA) methodologies are applied in orderThree distinct water groups were found, illustrating a different evolution of salinity (EC and TDS).

摘要:

To investigate the role of sulfuric acid-based carbonate weathering in global CO2 sequestration of climatechanges, we systematically discussed the pathway of sulfuric acid in rock chemical weathering and its

摘要:

The distribution and anomalies of rare earth elements (REEs) of granitic regolith were studied in InnerEu, Ce, and Gd anomalies of the two profiles are different.

摘要:

The samples were collected from various Unai geothermal location and analysis of chemical compositionof water obtained from different wells was done.been analyzed to delineate the path of water movement in the subsurface and classify the reservoir based
