Summary: Studies on vertical soil nutrient distribution beneath different types of artificially restored vegetation in a transition zone from desert to loess revealed distinct hierarchies in soil nutrient content, with Medicago saliva vegetation being the most suitable for restoration. Soil nutrient content was positively correlated with soil water content, plant coverage, and clay, silt, and litter nutrient content, but negatively correlated with soil bulk density, sand content, and litter C/N ratio.

Summary: The study investigated the influence of collapsing gully management restoration on soil quality and function, finding that different vegetation restoration types significantly impacted soil properties. Natural restoration mixed forest (NF) showed the highest soil quality index (SQI) value, followed by replanted arboreal forest (RA) and replanted scrubland (RS), all of which were significantly higher than the SQI value of the erosion area (EA) in the collapsing gully. Vegetation type explained the most substantial proportion of total variability (46.41%), and restoration time showed a positive correlation with SQI.

Summary: The construction of high-speed roads has led to an increase in hazards from steep cut slopes. Restoring vegetation on these slopes using outside soil spray seeding is effective, but challenging. This study found that adding 5-10% cement and 0.09% soil aggregate to artificial soil can improve adhesion and nutrient availability, making it a viable option for ecological restoration of steep slope vegetation.

Summary: Forest disturbances and restoration are crucial for carbon transmission. This study focused on the Greater Hinggan Mountains forest area in China and used remote sensing techniques to monitor post-fire vegetation restoration. The results showed that the chosen remote sensing indexes were sensitive to fire and burn severity levels, and natural restoration was faster than artificial methods. Additionally, forest canopy density did not differ significantly between severity levels and restoration methods after 33 years of recovery.

Summary: Understanding the integrated effects of different vegetation types on sandy soil physicochemical properties and quality is crucial for guiding vegetation reconstruction and ecological restoration in desertified areas. This study found that the different vegetation types significantly influenced soil properties, with fenced Leymus secalinus Tzvel. grassland (LS) having the greatest impact. LS may be the preferred vegetation restoration type for ecological restoration and reconstruction in this region.

Summary: Forest fires can have significant impacts on soil nutrient availability and plant diversity, especially in ecosystems where fires are infrequent. After a fire, the availability of nitrogen (N) increases in the first year but rapidly decreases in the following years, particularly in areas of high fire severity. However, phosphorus (P), potassium (K), and soil organic matter (SOM) are less affected and remain relatively stable over time. In the short term, plant species richness and diversity decrease in severely burned areas, but they gradually recover and become similar to those of unburned forests over time.

Summary: Restoration has become a global priority, with initiatives such as the UN Decade on Ecosystem Restoration. Monitoring vegetation recovery using NDVI and EVI showed non-linear patterns in forest regeneration, with an initial increase in both indices indicating successful onset of forest recovery. Differentiation between primary forests and regenerating forests was possible based on unique combinations of low mean and seasonal variation in EVI.

Summary: The study found that there was a significant increase in leaf area index (LAI) and evapotranspiration across most regions of the Loess Plateau, but a decrease in the evaporative stress index (ESI) overall. This decrease in ESI was mainly attributed to the increase in LAI rather than climatic influences. Additionally, soil moisture storage showed an increasing trend in the central and eastern parts of the plateau.

Summary: This study conducted a decomposition experiment across four successional stages to investigate the dynamics and mechanisms of litter decomposition and soil organic carbon (SOC) sequestration following vegetation succession. The results showed that litter decomposition rates decreased gradually with vegetation succession, and litter quality was the major factor controlling the decomposition rate. The early successional stage had higher rates of litter decomposition and SOC turnover, while the late successional stage showed lower rates. Litter inputs significantly increased SOC content in the early stage, but soil carbon sequestration reached saturation in the late stage.

Summary: This study analyzed the relationship between vegetation dynamics and drought in the Pearl River Basin using long time series data. The results showed that solar-induced chlorophyll fluorescence (SIF) had a more significant response to meteorological drought compared to the normalized difference vegetation index (NDVI). The vegetation response time also varied among different vegetation types. Furthermore, the El Nino Southern Oscillation, Pacific Decadal Oscillation, and sunspots were identified as important driving factors in the response relationship between drought and vegetation.

Summary: This study explores the relationship between snow cover and spring soil moisture in different land use types in Northeast China. The results show that snow cover significantly impacts farmland soil moisture, while there is little correlation between snow cover parameters and soil moisture in woodlands and grasslands. Future climate warming may introduce drought risk to woodland and grassland areas, requiring advance preparations, while farmland areas will continue to maintain appropriate soil moisture, which is beneficial for agricultural development.

Summary: In recent years, the synthesis of artificial humic substances (A-HS) through alkaline hydrothermal processing of waste biomass has been described. These A-HS have shown to have various effects on soil, including water and mineral binding, soil structure alteration, inhibition of fertilizer mineralization, and promotion of plant growth. The observed macroscopic effects have been attributed to the stimulation of the microbiome, which plays a key role in this anthropogenic soil system. By understanding this complex system, it is possible to address global issues such as soil fertility, nutrition for a growing population, and climate change.

Summary: In this study, the effects of freeze-thaw cycles, straw and biochar applications on soil hydrothermal parameters were investigated. The results showed that freeze-thaw cycles affected soil porosity and destroyed soil aggregates, while straw and biochar applications increased total soil porosity and enhanced soil aggregate stability. The applications of straw and biochar also increased soil saturated hydraulic conductivity, with biochar showing a stronger improvement effect. A 1% biochar application was recommended as the optimal soil amendment.
