Fig. 6: Spatial patterns of stocking rate thresholds predicted under different climate conditions and CO2 levels for period 2020–2100.
From: An early warning signal for grassland degradation on the Qinghai-Tibetan Plateau
a Simulation based on current climate conditions and CO2 level (2020) during period 2020–2100. b–d Simulations based on average climate conditions and CO2 levels of period 2020-2100 under the indicated representative concentration pathway (RCP) scenarios (RCP2.6, 4.5, 8.5). e Distribution of stocking rate thresholds in terms of area percentage of surface under different scenarios. Dotted lines represent the original data, for which the solid line indicates a 5-year running average. Maps were masked with an initial grassland distribution as showed in Fig. 1.
