Patterns of carbon (C) allocation across different stages stand development in Eucalyptus urophylla × E. grandis plantations are not well understood. In this study, we examined biomass and mineral soil C content five (1, 2, 3, 4–5, 6–8 years old) a southern China. The tree pool increased with age showed high annual rate accumulation. Stems accounted for the highest proportion sequestered. initially after afforestation then declined gradually, density decreasing depth. upper 50 cm contained...
Understanding the spatial distribution of tree species in subtropical evergreen-deciduous broadleaf karst forest is fundamental to studying coexistence and diversity. Here, complete randomness heterogeneous Poisson process models were used analyze patterns 146 with at least one individual per ha a 25-ha plot southwest China. We canonical correspondence analysis (CCA) torus-translation test (TTT) explain distributions observed species. Our results show that an aggregated was dominant pattern...
In karst ecosystems, plants absorbing smaller amounts of nutrients, owing to shallow soil, show limited growth. addition, fine roots (diameter < 2 mm) contribute the regulation nutrient cycles in terrestrial ecosystems. However, spatial and temporal variations root biomass different vegetation types region remains poorly understood. this study, we investigated seasonal vertical variation biomass, necromass, total mass using sequential soil coring under stages restoration (grassland,...
The conversion of farmland to forest in China has been recognized for its positive impact on above-ground vegetation and carbon sequestration. However, the soil quality during land conversion, particularly vulnerable karst areas, received less attention. In this study conducted a area southwest China, eight different strategies were investigated assess improvements surface carbon, nitrogen, ecosystem multi-functionality (EMF). Our results showed that converted afforestation areas or was...
Introduction Soil carbon and nutrient contents their stoichiometric characteristics play a vital role in indicating plant growth element balance, which can be used to indicate limitation. However, it has been less studied about driving factors within forest soils at the regional scale southern China. Methods In this study, soil organic (SOC), total nitrogen (TN), phosphorus (TP) were analyzed topsoil (0–10 cm) 345 sampling plots representing different types Guangxi Province. Results The...
We investigated the spatial patterns of woody species and their relationships with environmental factors in karst forest southwest China. Data for 30 plant an importance value ≥ 5 15 50 quadrats a plot 200 m × 100 were used this study. Two-way indicator analysis revealed that communities could be divided into 11 vegetation groups classified four ecotypes at third divisional level. Detrended canonical correspondence demonstrated variables significantly related to slope position, aspect,...
Soil organic carbon (SOC), nitrogen (N), and phosphorus (P) are three essential soil nutrients for plant growth, their stoichiometric ratios already important indices of elemental balance the fertility status in ecosystems. The evolution mechanism SOC, Total Nitrogen (TN), Phosphorus (TP), stoichiometry following “conversion cropland to forest program” (CCFP) southwest China is not yet clear. Seven different CCFP restoration models, including Zenia insignis (RD), Toona sinensis (XC),...
Spontaneous vegetation succession after agricultural abandonment is a general phenomenon in many areas of the world. As important indicators nutrient status and biogeochemical cycling ecosystems, stoichiometry key elements such as carbon (C), nitrogen (N) phosphorous (P) soil microbial biomass, their responses to recolonization remain poorly understood. Here, based on space-for-time substitution approach, surface samples (0–15 cm) were collected from four types, e.g., tussock grassland,...
The forest ecosystem is an important part of the terrestrial carbon sink, and its rate biomass accumulation influences sink potential. Therefore, it particularly to understand productivity ecosystems, their driving factors, especially in karst areas with a fragile ecological environment. We established 2 ha plot southwest China, investigated species composition, community structure, topography soil nutrients years 2007 2017. In this analysis, correlations between tree diversity each factor...
Spatial patterns and drivers of soil microbial communities have not yet been well documented. Here, we used geostatistical modeling Illumina sequencing 16S rRNA genes to explore how the main taxa at phyla level are spatially distributed in a 25-ha karst broadleaf forest southwest China. Proteobacteria, dominated by Alpha- Deltaproteobacteria, was most abundant phylum (34.51%) soils. Other dominating were Actinobacteria (30.73%), Acidobacteria (12.24%). Soil showed spatial dependence with an...
Soil bacteria participate in nutrient cycling above and below ground to promote ecosystem stability health. However, the relationship of soil environmental factors following Grain for Green (GfG) program remains poorly understood southwest China. samples were collected from seven sites that had been revegetated 15 years. Four these afforested with a different tree species: Zenia insignis (ZI), Toona sinensis (TS), Castanea mollissima (CM), Citrus reticulate (CR). One site was Guimu-1...
In karst regions, the spatial heterogeneity of soil mineral oxides and environmental variables is still not clear. We investigated SiO2, Al2O3, Fe2O3, CaO, MgO, P2O5, K2O, MnO contents in soils slope land, plantation forest, secondary primary as well their relationships with a region Southwest China. Geostatistics, principal component analysis (PCA), canonical correlation (CCA) were applied to analyze field data. The results show that SiO2 was predominant (45.02%–67.33%), followed by Al2O3...
Natural vegetation restoration has become an effective and rapid way for eco-logical in fragile areas. However, the response of soil microorgan-isms remains unclear. Using high-throughput sequencing methods, we evalu-ated dynamics bacterial fungal communities during forest suc-cession (shrubland, secondary forest, primary forest) karst region Southwest China. Secondary had significantly higher α-diversity than shrubland forest. Soil community was close to but diverged from that could be...
