Forest biomass allocation is a direct manifestation of biological adaptation to environmental changes. Studying the distribution patterns forest along elevational gradients ecologically significant for understanding specific impacts global change on plant resource strategies. While aboveground has been extensively studied, research belowground remains relatively limited. Furthermore, and driving factors proportion (BGBP) are still unclear. In this study, we investigated influences climatic factors, soil nutrients, key leaf traits pattern BGBP using data from 926 forests at 94 sites across China. were calculated root depth 50 cm. Our findings indicate considerable variability in macro scale, showing increasing trend (p < 0.01). significantly decreases with temperature precipitation increases annual mean evapotranspiration (MAE) It phosphorus content pH Key (leaf nitrogen (LN) (LP)) positively correlated BGBP. Climatic (R2 = 0.46) have strongest explanatory power variation elevations, while 0.10) 0.08) also play roles. Elevation directly indirectly through influencing such as climate conditions, nutrient availability, traits, effects being more pronounced than indirect effects. This study reveals controlling forests’ gradients, providing vital ecological insights into impact strategies offering scientific guidance ecosystem management conservation.

Soil chemical properties and soil microbial communities are the key factors affecting content of tea. The mechanism by which altitude changes soil’s community structure to affect tea is unclear. This study was conducted on a typical plantation in Fenghuang Mountains Chaozhou, China. It systematically revealed relationship between with quality components different altitudes (396 m/517 m/623 m). We discovered that pH Catalase activity appeared decrease then increase altitude, SOM Acid Phosphatase were significantly higher at mid-altitude. TP TK lowest high (0.20 mg/kg, 5.98 mg/kg). Non-significant differences found spatial composition altitudes. abundance fungi (Sobol index) (p < 0.05) low than other groups. Redundancy analysis indicated drivers bacterial structure. Fibrobacteres, functional group bacteria, showed decreasing trend increasing Stachybotrys (fungi) likewise had 0.05). catechin, theanine, caffeine leaves accumulated least (12.91%, 0.39%, 2.88%). Fibrobacteres Stachybotrys, as well content, strongly associated accumulation major contents leaves. Meanwhile, fungal positively correlated theanine enhances our understanding property–soil community–tea tree interactions. By exploring nutrient flora driving altitudes, it provides basis for precise microecological management gardens.

Agricultural greenhouses (AGs) are an effective solution to address the growing demand for vegetables despite limited cropland, yet significant soil quality problems often accompany them, particularly in high-altitude regions. However, effects of natural factors and production management on not well understood such fragile environments. This study analyzed differences between AGs adjacent open cropland (OCs) Lhasa River Valley, Tibetan Plateau, based 592 samples 12 key physicochemical indicators. GeoDetector was used identify dominant their interactions with these differences. The results showed that AG soils had significantly lower pH, average decrease 20%, indicating acidification, while nutrient levels total salinity were higher compared OC soils. Specifically, available phosphorus, potassium, fertility index, soluble salt increased by 281%, 102%, 38%, 184%, respectively. Planting, topographic, fertilizer identified as contributing Interaction analysis interaction explanatory power 20.2% 41.32% individual factors. planting year type highest increases pH decline, amount slope aspect contributed accumulation. These findings provide valuable insights practical guidance optimizing ensuring sustainable agricultural development
