Haibei Station has made new progress in the study of the influence of component attribute evolution on the water conservation function of alpine grassland

As the world’s “third pole”, the Qinghai-Tibet Plateau is home to a large number of glaciers, frozen soils, lakes, wetlands and alpine grasslands.

Grassland degradation can lead to major changes in its component attributes and ecological and hydrological processes, and affect the water conservation function of alpine grasslands.

1.

The cumulative rainfall of the alpine Kobresia humilis meadow from 2018 to 2019 at Haibei Station was 684.

Related research results were published in the International Journal of Ecological Hydrology Hydrological Processes (JCR area, impact factor 3.

2.

Haibei Station has continuously monitored the severely degraded grassland treated by reducing grazing for 7 years, and the grassland has been restored from the severely degraded stage to the moderately degraded stage

　　Relevant research results were published in Frontiers in Plant Science (JCR District 1, Impact Factor 5.

　　3.

　　The soil water conservation capacity of alpine shrub meadow is higher than that of alpine meadow, and the soil water conservation capacity of different vegetation types responds differently to grassland degradation

　　Related research results were published in the International Journal of Ecology Ecological Indicators (JCR District 1, Impact Factor 4.
