  "abstract": "The degradation of salinized meadows under environmental change calls for reliable functional indicators to support adaptive grazing management. However, while plant functional traits mediate grazing effects, identifying those that can robustly indicate the coupling between environmental factors and productivity across different grazing systems remains unresolved. Through a four-year controlled grazing experiment in a salinized meadow, we evaluated whether grazing systems select leaf number (LN) as a functional indicator of environment-productivity linkages. By integrating structural equation modeling and random forest analysis, we disentangled the cascading network connecting climate, grazing, traits, diversity, and ecosystem functioning. Our results showed that rotational grazing enhanced community productivity through increased LN, whereas continuous grazing shifted the system toward a height-avoidance strategy. Air temperature emerged as the dominant climatic driver, promoting LN and productivity under rotational grazing, while precipitation played a secondary role. Across all grazing systems, LN was the most important predictor of aboveground biomass (relative importance: 18.4%), surpassing plant height and stem length. LN also showed a synergistic relationship with the Shannon-Wiener index ( P < 0.01). These results demonstrate that grazing acts as a selector of ecological pathways rather than merely an intensity gradient. We therefore propose LN as a practical indicator linking grazing management to ecosystem responses under the interannual climatic variability, providing a trait-based tool for forecasting salinized meadow functioning.",
