Vertical greening systems, in addition to enhancing the aesthetic design of building facades, contribute energy saving and carbon reduction. This study proposes a simplified calculation method for annual comprehensive reduction potential vertical considering both indirect direct sequestration. The energy-saving systems was numerically simulated using EnergyPlus 9.2.0 typical three-story office four cities different climate zones: Xi’an, Shanghai, Guangzhou, Kunming. that sequestration full year as result system these areas were calculated. results show Virginia creeper reduced consumption by 1.2%, 3.1%, 8.7%, 4.0% Kunming, respectively. impact most significant where air condition period longest. When leaf area index is 3, Guangzhou can reach 1105.45 kgCO2/a. In regions with higher summer conditioning consumption, exhibits better potential. Kunming growing season longer, shows total has highest overall provides benefits across all zones strongly support industry’s efforts achieve neutrality.

Stand States Drive Disparities in the Carbon Storage Within a Masson Pine Forest Ecosystem

Forests, Год журнала: 2025, Номер 16(3), С. 499 - 499

Опубликована: Март 12, 2025

Forest ecosystems are important for carbon storage but vary in their ability to do so. Here, we examined the relationship between stand state and ecosystem Pinus massoniana forests, pinpointed key indicators affecting storage, provided a basis management enhance storage. We selected nine representing structure (diameter at breast height (DBH) distribution, tree density), vitality (stand dominance, growth, health), diversity (species composition, species diversity, evenness) evaluate state. Multivariate statistical analyses, specifically Mantel test Canonical Correspondence Analysis (CCA), were employed explore complex relationships states of P. forests found that (1) has strong influence on there is autocorrelation among states; (2) structural attributes have stronger association with than diversity. The primary associated DBH distribution (H), growth (B), density (K), (V), evenness (P); (3) (K) significantly affects vegetation layer, while (H) soil layer. None stand-state indicators, however, major litter Our results indicate can be managed improve forest quality forests.

Estimating Spatiotemporal Dynamics of Carbon Storage in Roinia pseudoacacia Plantations in the Caijiachuan Watershed Using Sample Plots and Uncrewed Aerial Vehicle-Borne Laser Scanning Data

Remote Sensing, Год журнала: 2025, Номер 17(8), С. 1365 - 1365

Forest ecosystems play a pivotal role in the global carbon cycle and climate change mitigation. aboveground biomass (AGB), critical indicator of storage sequestration capacity, has garnered significant attention ecological research. Recently, uncrewed aerial vehicle-borne laser scanning (ULS) technology emerged as promising tool for rapidly acquiring three-dimensional spatial information on AGB vegetation storage. This study evaluates applicability accuracy UAV-LiDAR estimating spatiotemporal dynamics Robinia pseudoacacia (R. pseudoacacia) plantations gully regions Loess Plateau, China. At sample plot scale, optimal parameters individual tree segmentation (ITS) based canopy height model (CHM) were determined, was validated. The results showed root mean square error (RMSE) values 13.17 trees (25.16%) count, 0.40 m (3.57%) average (AH), 320.88 kg (16.94%) AGB. regression model, which links with AH generated estimates that closely matched observed values. watershed ULS data used to estimate R.

Comparison of Growth Strategies and Biomass Allocation in Chinese Fir Provenances from the Subtropical Region of China

Forests, Год журнала: 2025, Номер 16(4), С. 687 - 687

Опубликована: Апрель 16, 2025

This study aims to evaluate the growth characteristics of six Chinese fir (Cunninghamia lanceolata (Lamb.) Hook.) provenances (S1–S6) from different climatic regions in subtropical China order select superior with strong adaptability, fast growth, and reasonable biomass allocation. These results will provide references for genetic improvement resource utilization plantations. A total 385 trees, aged 26 48 years, were selected gene bank Anhui. Wood core sampling was used obtain tree ring width early/latewood data. Growth rate, fast-growth period, allocation each provenance analyzed using methods such as logistic equation, BAI (basal area increment), latewood percentage, estimation. The period starts 2nd 4th year, significant occurring around 14th year stabilizing between 30 50 years. Provenance S2 showed clear advantages rate biomass, while S6 relatively weak. analysis revealed that reached their peak 10 years age, a gradual decline afterward, but maintained higher levels longer period. Root-shoot ratio had most balanced ratio, promoting stable efficient water nutrient absorption, root-shoot indicating limitations. Furthermore, demonstrated continuous increase after excellent potential. provides quantitative adaptability provenances, offering scientific support construction breeding plantations, contributing enhancing productivity ecological plantations sustainable utilization.

Monitoring Changes in Composition and Diversity of Forest Vegetation Layers after the Cessation of Management for Renaturalization

Forests, Год журнала: 2024, Номер 15(6), С. 907 - 907

Опубликована: Май 23, 2024

Overstory and understory vegetation play a vital role in forest ecosystem functionality. However, it is necessary to enhance the knowledge of their diversity compositional dynamics following cessation disturbance, which required inform restoration approaches mechanisms for maintaining disturbance cessation. We conducted chronosequence spanning 0–1, 5–6, 11–12, 20–24, 28–34 years since cessation, old-growth forests investigate dynamic changes overstory composition, as well maintenance anthropogenic disturbances subtropical regions Eastern China. The current study results indicated decrease cover periodic fluctuations overstorey efforts. Specifically, shrub layer exhibited highest richness years, while herb showed lowest evenness. Multivariate analysis using multiple-response permutation procedures that species composition interspecific quantity ratio plants at significantly differ from those early closure stage. An indicator revealed more support was given sun-loving after 0–1 enclosure, with shade tolerance low nutrient requirements were supported years. structural equation model show 38.8% impact on evenness related light substrate diversity. ecological time mainly indirectly affects by influencing upper vegetation, availability, heterogeneity. Overall, this can maintain care understorey plant contribute sustainable management forests.
