The change of soil temperature to stocking rate on the Stipa brevi f lora desert steppe
Stocking rates are one of the most important factors in grazing management,and are a key determinant in the grazing intensity of grasslands.In recent years,it has become widely accepted that over grazing can lead to grassland degradation.Many studies have shown that over grazing leads to significant reductions in plant communities.height,density and ground coverage.The changes in these grassland plant features can lead to changes in the grassland uptake of solar radiation energy and sun reflection,consequently effecting the change in soil temperature and atmospheric temperature in grassland ecosystems.Further it affects the nutrient cycle and energy flow of the whole grassland ecosystem.All these changes may lead to unpredictable changes on the whole climate system.As such,this experiment studied the effect of different stocking rates on soil temperature in the Stip a brev i f lora Desert Steppe,and in doing so tried to provide some scientific insights into grassland degradation and global warming.
