There are four sizable black soil regions throughout the world, all of which valuable natural resources. The region in Northeast China is a major foundation for grain production. Serious risks erosion do exist, and they have an immediate impact on both country’s food security future ecological security. Many water conservation measures been put place to control erosion. However, how effective suitable these measures? Currently, systematic analyses assessments lacking. objective this study was assess effectiveness suitability hillslopes using comprehensive index method Pressure–State–Response model. categorization were similar methods: that is, very included no-tillage + straw mulch ridge belt or contour ridge. two methods validated one another. Thus, standard useful choosing best different regions.

Abstract Accurate information on the distribution of regional black-soil resource is one important elements for sustainable management soils. And its results can provide decision makers with robust data that be translated into better making. This study utilized all Sentinel-2 images covering area from April to July in 2022. After masking clouds, were synthesized monthly. Based revised random forest classification algorithm, model performance using different feature combination programs evaluated search an efficient, high-precision method mapping resource. The impact adding temperature, precipitation and slope geographic covariates was analyzed. robustness verified Landsat-8 lower spatial resolution. showed (1) based multi-temporal ensemble features shows best performance, OA 94.6%; (2) temperature covariate effectively improve accuracy mapping; (3) compared sentinel data, reduced but still plausible, verifying model. provides a rapid

Rapid urbanization and climate change exacerbate soil erosion globally, threatening ecosystem services sustainable development. However, current predictive studies on future often lack comprehensive consideration of the interactions between land use change. This study proposed a scenario analysis framework that integrated four Shared Socioeconomic Pathways (SSPs) from CMIP6 with bespoke land-use scenarios (Inertial Development (IDS), Urban Priority (UDPS), Ecological Protection (EPPS), Farmland (FPPS)) to create 16 scenarios, allowing for more nuanced understanding potential trajectories. The results indicated (1) compared baseline period (2000-2020), in Central Yunnan Agglomeration (CYUA) would improve, albeit significant differences among scenarios. most notable improvement was under EPPS + SSP1-2.6 (ScC1). (2) lower Jinsha, upper Nanpan, Red river basins were high-risk areas CYUA, each dominated by different factors, necessitating differentiated control measures. (3) Land-use jointly influenced direction development, lightest occurring heaviest FPPS. largest decrease occurs SSP1-2.6, whereas smallest SSP5-8.5. (4) Climate had impact than change, reduction rates modulus area relative past 20 years being 9% 3.77%, respectively, approximately eight times magnitude recommends reducing carbon emissions, enhancing vegetation cover, controlling slope development effectively mitigate risk CYUA promote regional method provides new insights into global small-scale predictions.

Black soils refer to with black, thick upper layers containing 0.6% or more soil organic carbon in the tropical region. This high content makes these essential for climate change control and food production. In Indonesia, black are found under forests, shrublands, grasslands monsoon savannah climates. Land clearing agricultural uses will properties; however, knowledge of (level, direction, sensitivity) is limited. Meanwhile, surveying records land-use types collects samples, resulting voluminous legacy data. study aimed compare mean difference properties between two land-cover/use types. We used 142 datasets data on particle size distribution (sand, silt, clay), pH, (SOC), total nitrogen (TN), available P2O5 (AP), exchangeable cations (Ca, Mg, K, Na). calculated Hedges’s g-index effect assessment performed a Welch’s t-test significant differences. The results show that, compared forest, dryland monoculture home gardens have large trigger changes many properties. contrast, mixed paddy fields small size. decreasing order, sensitive TN > SOC = K Mg phosphorus pH Na sand silt clay Ca. suggest that combination better supports security mitigates soils. addition, can be monitor property changes.

Understanding the spatial variability and driving mechanisms of humus horizon thickness (HHT) degradation is crucial for effective soil prevention in black regions. The study compared ordinary kriging interpolation (OK), inverse distance weighted (IDW), regression (RK) using mean error (ME), absolute (MAE), root square (RMSE), relative RMSE to select most accurate model. Environmental variables were then integrated predict HHT characteristics. Results indicate that: (1) RK was superior OK IDW characterizing with smallest ME (11.45), (14.98), MAE RRMSE (0.44). (2) average annual temperature (0.29), precipitation (0.27), digital elevation model (DEM) (0.21) primary factors influencing HHT. (3) exhibited notable variability, an increasing trend from southeast towards central northern directions, being thinnest southeast. It thicker northeast southwest regions, but less dense along southern Bohai coast, yet sporadically distributed northwest (especially Chaoyang Fuxin), thick aggregated distribution over a smaller area northeastern direction (e.g., Tieling). These findings provide scientific basis management Liaoning Province.

The Northeastern Black Soil Region in China is recognized as one of the three major black soil regions globally and often regarded a cornerstone national food security. However, prolonged agricultural practices have led to increasingly severe degradation, mechanisms driving factors behind degradation quality remain unclear. Therefore, this study examines historical current characteristics quality, focusing on influencing factors, such 70-year history reclamation climate change. By accessing different databases, reviewing relevant literature, performing Pearson correlation redundancy analyses (RDA), investigated variation patterns significant indicators their 0–20 cm layer along latitudinal direction (Nenjiang, Beian, Hailun, Harbin) typical region Northeast China. main conclusions are follows: organic matter (SOM) content experienced rapid decline 30 years preceding cultivation (1950~1980), with greatest rate Beian area (about 1.10 g/kg per year). SOM Harbin areas decreased from north south, changing at rates 9.40–21.67 g/kg/degree 0.15–0.34 g/kg/m latitude elevation, respectively. Elevation impacts annual change through its influence mean maximum temperature (AMXT) atmospheric pressure (AP). AMXT AP exhibit linear relationship based which regression models were established. key include (Y), minimum temperatures (AMXT AMNT), relative humidity (ARH), AP. An increase chemical fertilizer application among critical affecting pH. Additionally, extensive use machinery can reduce porosity cause water salt accumulation, ultimately leading This offers theoretical support for mitigating China’s region, thereby contributing security promoting sustainable development.
