Abstract Road construction constitutes a significant disruption to natural ecosystems. Globally, high-elevation regions are among the most fragile and sensitive ecosystems, while systematic information regarding impact of road on soil properties plant communities in these remains scarce. In this study, paired plots were established along route from Yunnan Province Tibet Autonomous Region Southwest China, with elevation ranging 2,400 m 4,900 m. Results revealed restoration post-disturbance had been multifaceted long-term progress. Specifically, disturbed exhibited increase pH, moisture, TC, TN, TP, NH 4 -N, AK suffered substantial loss. Moreover, strong recovery ability shrub herbaceous species was observed our tree difficult revert their original state. Furthermore, influence vegetation also varied depending life forms. light findings, appropriate strategies proposed mitigate negative impacts promote ecosystem after ecologically regions.

Projections of spatial biodiversity dynamics under climate warming are often based on models including only variables, and when non-climatic factors (e.g. soil) included, data at much coarser resolutions than those experienced by plants. Field studies along elevation gradients permit the gathering detailed soil data, while still covering a wide climatic gradient. Here, an intensive field survey four spring forest herbs gradient showed that properties had substantial impacts occurrence/abundance all species, effects were more pronounced higher elevations. For

Altitude, as a key environmental factor, shapes the spatial patterns of species diversity, phylogenetic and community structure. Studying grassland diversity structure along altitudinal gradients helps clarify how altitude-driven changes influence assembly, reveal vertical in formation. This study examines grasslands at 1300–2500 m elevation Two-River Source Forest Area, Altai Mountains, Xinjiang. Six (200 intervals) were surveyed with 90 quadrats, documenting characteristics data. The analyzes composition, phylogeny across different explores their relationships factors. results indicate that composition is dominated by from Poaceae, Rosaceae, Asteraceae families, Poa annua (annual bluegrass) being dominant within Poaceae. gradient exhibits bimodal trend, an initial increase, followed decrease, another finally decline rises. In contrast, shows unimodal pattern, characterized increase increasing elevation. Although did not exhibit significant trend transitioning divergence to clustering gradient, overall pattern communities tended toward clustering. Further analysis reveals correlations between factors such temperature, precipitation, forest cover, soil moisture. However, no found have correlation indices.

Soil asymbiotic nitrogen (N) fixation provides a critical N source to support plant growth in alpine grasslands, and precipitation change is expected lead shifts soil fixation. However, large gaps remain understanding the response of gradients.

Revealing alpine plant diversity patterns can contribute to conserving mountain diversity. However, the spatial variation in ecological niche and of community mechanism by which it maintains itself desert grasslands remain poorly understood. Here, we conducted a field investigation across altitudinal gradients (3093, 3296, 3549, 3790 m) northern Tibetan Plateau compared species composition, indices, Levins' breadth, Pianka's overlap. The results showed that perennial herbs replaced semi-shrubs xermesophytes mesophytes xerophytes with increasing altitude. heights decreased cover herb layer increased altitude, whereas shrub was hump-shaped. Species indices (Patrick, Pielou, Shannon-Wiener, Simpson) Sympegma regelii (1.05), Leymus chinensis (1.03), Reaumuria kaschgarica (0.94) had larger breadths were widespread. high overlap occupied considerable proportion at higher altitudes, indicating strong interactions among species. redundancy analysis revealed soil water content, organic matter pH main factors driving changes (P = 0.036, F 3.7). Our study illustrated environmental filtering biotic jointly shape composition along gradients.
