The Alpine Grassland Biogeochemical Process Subject Group reveals that moderate grazing can significantly improve the water use efficiency of alpine meadows on the Qinghai-Tibet Plateau

Water use efficiency is an important indicator that affects the productivity of grassland ecosystems and grassland health

In late August of the 2020 growing season, the Alpine Grassland Biogeochemical Process Subject Group of the Northwest Plateau Institute of Biology, Chinese Academy of Sciences collected plant and soil samples in Huangcheng Township, Menyuan County, Qinghai Province, and studied different grazing based on the stable carbon isotope test index δ13C value Changes in water use efficiency of dominant species, coexisting species, functional groups, and community levels in intensity alpine meadows, and combining environmental factors to explore their adaptation mechanisms

The relevant research results were published in Frontiers in Ecology and Evolution (IF=4.
