The relationship between wetland water level changes and plant community has been a research hotspot. However, the gradient critical influencing factors of plateau lakeshore plants soils during wet-dry alternation remain unclear. Here, we studied variations in along Erhai across three elevation ranges (1965.0-1965.3m, 1965.3-1965.6m, 1965.6-1966.4m) flooding drought years. Our aimed to elucidate interrelationships mechanisms among hydrology, soil properties, dynamics. results showed that (1) In years, Shannon-Wiener index significantly decreased ranges, other diversity indices, biomass, coverage also varying degrees; (2) except for pH, (SW) nutrient content degrees year; (3) SW was primary factor coverage, 1965.0-1965.3m 1965.3-1965.6m ranges; nitrate nitrogen, C/N ratio, total phosphorus were 1965.6-1966.4m ranges. structural equation modeling revealed significant strong correlation pH. This suggests directly impacted biomass accumulation, subsequently affecting played role regulating study identified effects hydrological inter-annual on communities highlighted as crucial driver. strategies proposed protect improve stability lake ecosystems Lake similar lakes.
