- Abstract:
- Grazing is one of the most important human disturbance factors in the global grassland ecosystem. In order to understand the influence of grazing on grassland community characteristics and ecological functions, the typical grassland of Xilingol League was taken as the research site, the above-ground biomass (AGB) and community structure of 26 different grazing conditions were investigated in the period 2015-2017, and the changes of AGB and community structure under different grazing conditions and elevations were analyzed. Based on global precipitation measurement remote sensing daily precipitation data, the impact of precipitation on grassland biomass under different grazing conditions was discussed. The results showed that:(1) there were significant differences in the elevation gradients between the grazing point plants, and there were significant differences in plant species G3 and G1 and G2 at the grazing point; with the increase of elevation gradient, the plant species increased at first and then decreased, the plant height, plant species and AGB of grazing points at the elevation between 860 m and 1 100 m was smaller than that of non-grazing, and the plant growth at grazing point was better at higher elevation; (2) regardless of whether grazing or non-grazing, plant height was significantly positively correlated with AGB accumulation and the correlation at grazing point was more significant, the correlation between plant species and AGB was significantly lower than that of plant height and AGB; grazing had the greater impact on AGB accumulation; (3) different grazing conditions changed the relationship between AGB and precipitation, but did not change the relationship between plant species and precipitation; the relationship between plant species and precipitation under grazing conditions was related to the amount of precipitation in the growing season.
