The electronic properties of novel two-dimensional materials Cr4BA (A=C, N) predicted based on first-principles were studied, namely, the phonon spectrum, band structure, and … Read more →

Abstract.The Heihe River Basin was selected as the study area in this paper. Based on spatial and statistical data, the InVEST model and related formulas were used to quantify the supply and demand of four ecosystem services: Water Yield (WY), Soil Retention (SR), Carbon Sequestration (CS), and Food Production (FD). Using these results, the supply-demand ratio and Z-score standardization were applied to analyze the matching of supply and demand for ecosystem services in the basin. Finally, the driving factors affecting the ecosystem service supply-demand ratio were explored by using Geo Detector. The … Read more →
