Current studies regarding the effects of grassland management strategies on soil nutrient cycle have mostly focused organic carbon (SOC). Less is known about responses SOC, total nitrogen (TN), and phosphorous (TP) stocks to at different depths. We therefore quantified vertical variations in TN, TP as well controlling factors under three (i.e., enclosure control, grazing twice a year, combined with mowing) 2014 2017 semi-arid northern China. found that year mowing led an increase plant production C N sequestration during 2017. Changes aboveground biomass (AGB), belowground (BGB), root-to-shoot ratio (R:S) all exerted significant positive changes surface layer (0–30 cm), while AGB community composition played more important role mediating C, N, P response subsoil (30–100 cm). Specifically, influence capacity by altering composition. The results this study provide new insights into mechanisms plants soils practices offer range possible might be applied effective grasslands.

ABSTRACT Overgrazing affects the grass‐livestock balance and endangers grassland ecological security. Despite extensive studies conducted on identifying quantifying grazing intensity, there is still room for improvement in research gridding particularly areas with limited data Qinghai–Tibet Plateau. Therefore, we proposed a intensity spatialization method using geographically weighted random forest (GWRF) to gain further insights into spatial heterogeneity of alpine intensity. This incorporates multiple remote sensing related human activities natural factors, as well annual livestock statistics at township level over several years, while adequately considering autocorrelation Additionally, employed Lindeman Merenda Gold (LMG), geographical detector model, structural equation model (SEM) assess contribution influence path driving factors We also utilize partial correlation analysis dual‐phase mapping examine impact distribution The results demonstrate that GWRF‐based accurately predicts by demonstrating its consistency township‐scale ( R 2 = 0.92 p < 0.01), RMSE 1.07). provides valuable technical support pastoral availability. evaluate trends observe an increase Gar Purang counties.

Abstract The problem of grassland degradation induced by livestock production at the expense local grasses has become a serious ecological worldwide. To maintain and sustainable development, extent intensity utilization needs to be better understood. In this study, model was developed monitor grazing in typical area (Tibet Selinco basin) Qinghai‐Tibet Plateau. Combining number township scale with their matching habitat location, biomass consumed assigned productivity supply map (NPP) using mathematical iterative algorithm from perspective different foraging habits livestock. objective accurately measure overall pressure on pasture as well estimate utilization. confirmed distinct spatial differences Tibet basin, which significantly low except southwestern region. found 150,000 km 2 , moderate occupied 130,000 overgrazing 20,000 accounting for 87% 13% total area, respectively. proposed can quantify human activities spatially provide reliable accurate scientific basis development environment management.
