Nowadays, climate change is recognized as one of the biggest problems world facing, posing a potential threat to environment and almost all aspects human life. Since United Nations Framework Convention on Climate Change in 1992, many efforts have been made mitigate change, with no considerable results. According projections, temperatures will continue rise, extreme weather events become more frequent, prolonged, intense. Reflecting these concerns, 2015 Paris Agreement was adopted cornerstone for reducing impact aiming limit global warming below 2 °C even keep temperature rise 1.5 °C. To achieve this international goal, focused mitigation actions be required. has strong forests, enhancing their growth but also risks them. Conversely, forests can they surface through influence land–atmosphere energy exchange absorption vast amounts CO2 photosynthesis. Consequently, afforestation reforestation integral components strategies worldwide. This review aims summarize cutting-edge knowledge role mitigation, emphasizing carbon storage capacity. Overall, afforestation/reforestation hinges strategic planning, implementation, local forest conditions. Integrating other removal technologies could enhance long-term effectiveness storage. Ultimately, effective entails both restoring establishing alongside greenhouse gas emissions.

Nutrient limitation is a universal phenomenon in terrestrial ecosystems. Root and mycorrhizal are critical to plant nutrient absorption nutrient-limited However, how they modified by N P limitations with advancing vegetation successions karst forests remains poorly understood. The present study compared the diversity indices, composition, co-occurrence network of arbuscular fungi (AMF) between grassland, shrubland, shrub-tree forest, tree forest subtropical forests, as well soil nutrients fine root functional traits (e.g., specific length (SRL), area (SRA), diameter, biomass, contents). roots contents increased succession, whereas SRL SRA decreased. Network complexity Richness Chao1 indices AMF from grassland but decreased forest. were positively related their diameter nutrients, composition negatively correlated SRA. Moreover, these two parameters increase nutrients. variations mainly explained interactions traits, other three stages. Additionally, interactive explanation shrubland Our results indicated that strategy might be main acquisition under co-limitation. In contrast, one when an individual subject or strategies generally mutualistic, enhances

Urban areas play a crucial role in carbon absorption, while also producing considerable amount of emissions. However, there has been lack research that systematically examined the storage and sequestration green spaces located within urban environments, at spatial scale. This study analyzes Yurim Park, Daejeon, South Korea on grid basis to fill gap. The compares variation capacity across different grids provides insights into development sustainable parks planning. classification is based specific site characteristics, such as land cover, tree distribution, type, density. results total seven distinct types. employs combination I-tree eco model, drone-based modeling, on-site surveys estimate parks. show average per unit area entire park was 15.3 tons hectare, ranging from minimum 5.0 maximum 21.4 hectare. For planted area, 8.6 Grids with dominated by broad-leaved trees closed canopy cover had highest values. planting ratio type were found directly influence stands out previous conducting detailed area-based comparison analysis using sophisticated measurement techniques. findings offer direct strategies policies for securing future sinks can be practical use this regard.

Factors driving carbon accumulation in forest biomass and soil organic carbon across natural forests and planted forests in China

Frontiers in Forests and Global Change, Год журнала: 2024, Номер 6

Introduction Forests play a pivotal role within the global carbon cycle. However, how to enhance storage in existing forests remains unclear. Methods In this study, we conduct comprehensive analysis of data from 2,948 forest sites across China. Utilizing structural equation modeling (SEM), investigate intricate relationship between climate, tree species diversity, stand structure, function traits, initial biomass stocks (BCi), soil organic (Soil C content), and accumulation (ΔBC) (ΔSOC) both natural (NF, n = 1,910) planted (PF, 1,038). Results Our findings underscore critical influence diversity structure drivers direct indirect accumulation, with distinct emerging based on pools NF PF. Specifically, increasing its minimum maximum value through management-results 14.798 tC/ha reduction BC 0.686 SOC NF. Conversely, amplifies PF by 0.338 0.065 tC/ha, respectively. Enhancing structure-such as density-results 231.727 NF, 10.668 64.008 increment Discussion Overall, our results indicate that higher density age-group limits further current contrast, low development potential forests. To sequestration capacity, China should change policy completely banning logging Natural need thinning reduced while increase density.

The potential of optical and SAR time-series data for the improvement of aboveground biomass carbon estimation in Southwestern China’s evergreen coniferous forests

Accurate assessments of forest biomass carbon are invaluable for managing resources, evaluating effects on ecological protection, and achieving goals related to climate change sustainable development. Currently, the integration optical synthetic aperture radar (SAR) data has been extensively utilized in estimating aboveground (AGC), while it is limited by using single-phase remote sensing images. Time-series data, which capture interannual dynamic growth seasonal variations photosynthetic phenology forests, can sufficiently describe characteristics. However, there remains a gap research focusing utilizing satellite-based time-series AGC estimation, especially SAR sensors. This study investigated potential AGC. Here, we undertook nine quantitative experiments estimation from Landsat 8 Sentinel-1 tested several regression algorithms (including multiple linear (MLR), random forests (RF), artificial neural network (ANN), extreme gradient boosting (XGBoost)) explore contributions spatiotemporal features estimation. The results suggested that XGBoost algorithm was suitable with explanatory solid power stable performance. temporal representing trends periodic characteristics (such as coefficients continuous wavelet transform) were more valuable than spatial both sensor types, accounting around 40% ~50% variance compared 17% ~25%. combination produced best performance (R2 = 0.814, RMSE 18.789 Mg C/ha, rRMSE 26.235%), when or alone (optical: R2 0.657 35.317%; SAR: 0.672 34.701%). Feature importance analysis also verified vegetation indices, SWIR 1/2 bands, backscatter VV polarization most critical variables Furthermore, incorporating into modeling illustrated be effective reducing saturation within high-biomass forests. demonstrated superiority While applicability this methodology only evergreen coniferous may provide viable approach needed make full use increasingly better free satellite estimate high accuracy, supporting policy making management

Implementing thinning practices can enhance the growth of plantation forests and improve soil health. Nevertheless, impacts applications on quality, large-diameter timber production Castanopsis hystrix, ecosystem multifunctionality are poorly understood. Therefore, we chose two sample plots, unthinned (control) thinned, to investigate productivity after for six years. Results revealed that significantly reduced soil’s bulk density, enhanced growth, undermined in short term compared control (unthinning) treatment. Compared control, treatment considerably organic carbon (0–30 cm layer) tree diameter at breast height (20–30 cm), shrub leaf nitrogen (N), root N, herb aboveground Gram-positive bacteria (0–10 layer), contents by 29.61%, 65.29%, 44.61%, 274.35%, 323.44%, respectively. Furthermore, application could N P resorption efficiency more than control. with maximized decomposition nutrient cycling function 11.81% 143.40%, Moreover, total PLFA content stocks, wood production, water regulation functions. In conclusion, this study underscores considerable potential augmenting stimulating positive effects forest stands. These findings provide valuable insights elevation judicious forestry productivity, facilitating sustainable development sector.
