Abstract. Vegetation restoration is among the most effective measures for controlling runoff and soil erosion resulting from human activities. Nevertheless, few studies have been undertaken to analyze effects of grassland on maintaining local runoff, especially alpine degraded hillsides where mixed-cultivation grasslands predominate. In this research, plots were established investigate impact three grasslands, each sowing two grass species per plot a 20° slope: Deschampsia cespitosa Elymus nutans (DE), Poa pratensis L. cv. Qinghai (PE), (PD). The activation volume surface magnitude loss over 3 years (2019, 2020, 2022) assessed. A severely meadow (SDM) was used as control. findings indicated that can effectively maintain reduce planting age increases. Between 2019 2022, values average depth DE, PE, PD, SDM 0.47, 0.55, 0.45, 0.27 mm, respectively. Despite increase in favored conservation: net losses unit area 1.4, 1.3, 1.9 times greater than those key factors affecting rainfall amount, duration, intensity (60 min intensity). We conclude results study serve scientific guides formulate efficient policy decisions planning vegetation hillside meadows. To improve effectiveness restoration, we suggest protective should be prioritized during initial stage cultivated grasslands.

ABSTRACT The crucial role of soil water retention and storage in hydrology the cycle is well established. However, sensitive degraded ecosystems like alpine meadows, effectiveness revegetation enhancing these critical functions remains understudied. This study investigates effects revegetating severely hillside meadows with artificial grasslands on capacity Qinghai‐Tibetan Plateau. Soil analyses at a depth 0–20 cm revealed significant improvements properties after revegetation, increases organic matter content (86.8%), total porosity (11.9%), capillary (31.6%), clay (13.5%). Both saturated hydraulic conductivity ( Ks ) field (FC) increased markedly, by 9.7% 63.7% upper layer (0–10 cm) 21.7% 69.6% lower (10–20 cm), respectively. Structural equation modeling identified bulk density, root mass FC, porosity, as dominant direct factors influencing path coefficients −0.56, 0.30, −0.53, 0.57, −0.12, respectively, while vegetation cover aboveground biomass were found to have indirect influences. These findings demonstrate that effectively improves regulating key physical properties. enhanced water‐holding has implications for understanding dynamics grassland establishment improving ecosystem health eco‐hydrological vulnerable environments. Furthermore, provides valuable insights theoretical basis developing ecological restoration solutions other regions.
