| 英文摘要 | Magnesium (Mg) plays a crucial role in regulating plant photosynthesis and stress resistance. However, our under-standing of plant Mg at the community level remains limited because of lack of systematic investigations. This study, for the first time, comprehensively evaluated community-level Mg content and density, and determined their spatial patterns and driving factors, on the Qinghai-Tibetan Plateau (TP), using data from 680 ecosystems (169 forests, 22 shrublands, 466 grasslands, and 23 deserts). Mg density was 1.01, 2.36, 1.87, and 2.26 g m-2 in leaves, branches, trunks, and roots, respectively. Notably, we generated maps of plant Mg content and density with a 1 km x 1 km res-olution based on random forest models. Mg content decreased from northwest to southeast, but Mg density was higher in the east of the plateau, which reflected plant adaptive strategies to the unique radiation, oxygen, and temperature conditions (major driving factors) on the TP. Our findings provide insights into biogeochemical cycling and could fa-cilitate the optimization of remote sensing parameters. |
