The factors driving plant species diversity in different forest types and layers are still insufficiently understood. Therefore, we investigated the limiting of nutrient water use efficiency three (arbor, shrub herb layers) two (plantation natural forest), as well their potential relationship with diversity. study area is located mid-latitude evergreen broad-leaved ecosystems southern Anhui province. nitrogen content soil (2.90 g kg−1) exceeded national average for (1.06 kg−1), whereas phosphorus (0.43 was below such (0.65 kg−1). arbor layer comparatively low, exerted a more substantial influence on it. In contrast, had most significant impact layers. conclusion, has little effect growth patterns this area, while there role regulating succession rates. There phenomenon excessive deposition loss ecosystem. Despite fact that indices (the Pielou Evenness Index, Gleason Richness Shannon–Wiener Diversity Index Simpson Dominance Index) forests were higher than plantation forests, disparity between them not (p > 0.05). This may be due to similar climate. findings research hold significance forecasting alterations diversity, functionality, influencing within forests.
