Here, multi-proxy indicators including lithology, AMS¹⁴C dating, grain size, total organic carbon (TOC), total nitrogen (TN), elemental geochemistry, and microfossils in a new core (QTZ1) from the Wenzhou Coastal Plain (WCP) are employed to reconstruct sedimentary evolution, which experienced four phases as follows: (1) The terrestrial environment dominated by delta facies (before 11,700 cal a BP); (2) The marine-terrestrial transitional environment dominated by littoral facies (11,700–9,400 cal a BP); (3) The marine environment dominated by shallow marine facies (9,400–6,200 cal a BP), including the Holocene transgression maximum occurred during 8,400–7,400 cal a BP; (4) The marine-terrestrial transitional environment marked by littoral facies (after 6,200 cal a BP). A comparative analysis on the Holocene transgression intensity, as reconstructed by Sr/Ba in the WCP, and archaeological sites in the Ningshao Plain indicates that the ancestors gradually migrated to the eastern low-elevation plains and developed Neolithic rice cultivation after the transgression maximum.

Soil organic carbon (SOC) maintained high levels under light grazing, whereas it decreased with increasing grazing intensity. Reductions in plant carbon and absolute microbial abundance due to grazing, coupled with changes in soil carbon quality and the environment, drove the reduction in carbon mineralization.

This study analyzed the spatiotemporal changes of SOC in a typical agricultural region of the North China Plain from 1984 to 2019 and explored the potential for SOC sequestration. A total of 411 soil samples were collected in 1984, with subsequent sampling in 2009 (411 samples) and 2019 (181 samples). Geostatistical Sequential Gaussian Simulation (SGS) was utilized to quantify the spatiotemporal trends of SOC changes from 1984 to 2019. The SOC sequestration potential (SOC<em>_p</em>) was estimated using the Levenberg-Marquardt and Universal Global Optimization algorithms. The results revealed a significant elevation in mean SOC from 5.84 g kg⁻¹ in 1984 to 10.64 g kg⁻¹ in 2019, with an increasing trend observed from the northwest towards the southeast. The SOC increase rate during 2009–2019 (0.48 t/ha yr⁻¹) surpassed that of 1984–2009 (0.32 t/ha yr⁻¹). The fine-textured soil in the north showed a faster increase in SOC compared to coarse-textured soils in the south. Estimated SOC<em>_p</em> ranged from 2.81 to 24.34 t C/ha, with a mean of 12.43 t C/ha across the area. Loam clay, silt clay, clay loam and loam in the north exhibited lower SOC<em>_p</em> (0–10 t C/ha) compared to sandy loam in the south. The time required to reach SOC saturation (T<em>_s</em>) was high (&gt;20 years) in the south, an area dominated by sandy loam, compared to the north, with a low T<em>_s</em> (0–20 years) covered by fine-textured soil.

For example, low-relief, woodland regions have slope gradients, soil types, and substrate lithologies that contrast with steeper mountainous regions prone to rock fall and debris flows. Similarly, regional variations in precipitation, earthquakes, and other impacts on landslide surfaces create regional variations in landslide properties. While the controls on landslide characteristics have been extensively studied for high-relief coastal and tectonically active regions, controls on low-relief landslides have received comparatively less attention. We focus here on a part of the Ozark and Ouachita Mountains in the US southern mid-continent to explore such characteristics of landslides and potential controls in low-relief regions. The area exhibits frequent landslides in soil-covered low-relief forested hillslopes. We evaluated the frequency-size scaling of landslides occurred during periods of different earthquake frequency and precipitation amount (pre- and post-2005). We also produced maps of landslide susceptibility based on random forest machine learning applied to remotely sensed data. We found that landslides are clustered mostly in upland hillslopes, and that small landslides dominate the area, quantified by a landslide frequency-size distribution fitting a double Pareto curve. Additionally, the overall landslide frequency, and potentially the porportion of smaller landslides relative to the larger ones, significantly increased after 2005, the period during which the area also experienced increased induced seismicity and extreme storm events. Approximately 94 % of historical landslides were within random-forest-classified high-landslide probability (probability &gt; 0.5) zones, coinciding with moderate to steep (18° ± 9°) and convergent upland slopes underlain by shale and sandstone. Anomalously high frequency landslides appear to result from triggering by extreme weather, human-induced earthquake activity, and human-induced hillslope modification.</p></div>","PeriodicalId":9801,"journal":{"name":"Catena","volume":null,"pages":null},"PeriodicalIF":5.4,"publicationDate":"2024-08-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142083580","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The findings indicated pronounced differences in functional gene profiles between original remnant forests and created greenspaces. The artificial green spaces exhibited a heightened presence of genes related to aerobic methane oxidation, anaerobic carbon fixation, denitrification and nitrification, indicating that artificial green spaces may cultivate soil microbial communities with enhanced metabolic versatility. We revealed a positive correlation between soil nitrogen levels and the abundance of genes involved in various processes of the carbon and nitrogen cycles in these artificial green areas, highlighting the critical role of nitrogen in influencing the structure of microbial communities. Soil chemical properties (namely C, N, P, K content) and habitat type emerged as the most consequential for the gene composition related to the carbon and nitrogen cycles. The co-occurrence networks of functional genes constructed for these cycles suggest a tendency towards synergistic microbial interactions.

The studied Technosols were weakly developed soils with a simple soil profile comprising (1) C horizons in the subsoil and (2) O and A (or AC) horizons in the topsoil. The pH_H2O of soils was 5.5–8.1. High soil pH_H2O values were due to occurrence of carbonates (up to 25 %). The highest content of total organic carbon (TOC) and total nitrogen (TN) was found in O horizons as well as in A and AC horizons including buried A horizon. Soil magnetic susceptibility (χ) was 6.0–171.3 × 10^–8 m³ kg⁻¹. In each profile, the highest χ values were typical of A horizons including the buried A horizon. The most common minerals present in all profiles were quartz, kaolinite and mica. There were also admixtures of carbonates (dolomite, calcite), feldspars (orthoclase and albite), jarosite, goethite and traces of Fe sulphides. SEM-EDS analyses showed that soil substrate was subject to transformations of sulphides into Fe oxides. Moreover, pedogenic Cu carbonates were found in pores and on coarse materials. Technosols were enriched in Ag, As, Cd, Co, Cu, Hg, Mo, Ni, Pb, Sb, Zn, U and Th. The most mobile trace elements in the studied Technosols were Cd, Cu and Zn. Topsoil horizons of the studied soils contained a considerable share of Pb, Cu, Zn and Ni bound with soil organic matter. Arsenic was mostly bound with Fe oxides. First indicators of pedogenesis in the studied Technosols are (1) accumulation of soil organic matter in the topsoil followed by the decrease of soil pH and leaching of carbonates, (2) mineral transformations in the soil substrate (alteration of sulphides into Fe oxides and jarosite; origin of pedogenic Cu carbonates due to crystallization from soil solutions), (3) increase of magnetic susceptibility in the topsoil which may be an effect of atmospheric dust fall out or pedogenic transformation of Fe oxides into the phases with higher magnetic susceptibility and (4) the effect of soil properties, mineral composition and soil organic matter on geochemical forms of potentially toxic trace elements.

While, there is a scarcity of data evaluating the impact of land reclamation on peatland carbon stability. Here, based on ²¹⁰Pb dating of the Shenjiadian (SJD) peatland, we reconstructed historical variations in peatland carbon stability and assessed its response on regional land reclamation over the last century in the Sanjiang Plain. The results showed that the highest aromatic content (25.2 ± 0.7 %) and the lowest carbohydrate content (34.7 ± 2.5 %) occurred between 1950 and 1980, coinciding with the period of extensive second land reclamation in the Sanjiang Plain. The increase in regional human activities led to greater accumulation of pyrogenic carbon in the peatland, enhancing carbon stability in the 1950 s. However, as farmland area continued to grow in the 1960 s, local fires caused by agricultural activities led to more frequent peat fires, promoting the accumulation of herbaceous litter in the peatland, which decreased the stability of the peatland carbon pool but increased carbon accumulation rates. With the proportion of shrub litter increasing and regional land reclamation weakening after 1980, the accumulation of shrub litters has increased both carbon stability and carbon accumulation rates in the studied peatland, particularly after 2000.</p></div>","PeriodicalId":9801,"journal":{"name":"Catena","volume":null,"pages":null},"PeriodicalIF":5.4,"publicationDate":"2024-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142083586","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although biodiversity and other factors contribute to forest productivity to varying degrees, it is unclear whether spatial scale (or plot size) influences this relationship. In this study, we analyzed the impacts of biodiversity, trait composition, structural attributes, and soil fertility on forest productivity at three scales in two temperate old-growth forests. We found that structural attributes, including basal area and stand density, were positively correlated with productivity and were consistently the strongest drivers of productivity changes in both forest types. Trait composition had a weak direct positive correlation with productivity. Soil nitrogen had positive effects on productivity, and soil moisture content had negative effects, both of which increased with increasing plot size. Different results for the effect of biodiversity on productivity were found between the two forests. In the mixed broadleaved-Korean pine forest, diversity correlated positively with productivity, and the strength of the relationship increased with increasing plot size. In contrast, in the spruce-fir valley forest, diversity had a direct positive correlation with productivity at 10 m × 10 m, no significant effect at 20 m × 20 m, and a negative correlation at 30 m × 30 m. Our results suggest that the contribution of vegetation attributes and soil fertility to forest productivity varies with scale. Despite the fact that both the niche complementarity hypothesis and the mass ratio hypothesis act simultaneously in forests, they have limited effects on productivity. Stand structural attributes play a key role in elucidating the biodiversity-productivity relationships, and they may serve as a more significant regulator of forest productivity than diversity.
