The Yixing Yuantianjian small watershed is a provincial soil erosion key management area in the hilly region of southern Jiangsu. It has been implemented national control project for management, which typical and representative region. important to quantitatively evaluate quality under different land use modes then select suitable ecological restoration measures promote economic construction watersheds Used four types (forest land, garden arable abandoned land) as research object, 13 physical chemical property indicators were screened based on principal component analysis, correlation analysis Norm value calculation construct minimum data set (MDS) evaluation. results showed that variability was higher than study area. MDS affected by are sand content (Sand), total nitrogen (TN), available (AN), potassium (AK), porosity (TSP) bulk density (BD), provide valid information with high accuracy. index areas Jiangsu SQI forest (0.83) > cultivated (0.74) (0.66) (0.46), at medium level. AN factor limiting this watershed. This can scientific basis enhancement

Different vegetation restoration methods have improved soil quality to varying degrees. This study, focused on the forest-grassland-desert transition zone in Hebei-Inner Mongolia border region, and employed a systematic grid sampling method establish fixed monitoring plots Saihanba Mechanized Forest Farm Ulan Buh Grassland. The differences evolution across various under same climatic historical conditions were analyzed, elucidating roles of these degraded forest ecosystems, with aim providing reference for ecological similar land conditions. study used sample points transitional assessed five sites: artificial composed native species Larix principis-rupprechtii (FL), exotic Pinus sylvestris var. mongolica (FP), natural secondary broad-leaved (FN), open grassland (GO), enclosed (GC). organic carbon (SOC), total nitrogen (TN), phosphorus (TP), potassium (TK), alkaline hydrolysis (AN), rapidly available (AP) (AK) among different sites compared via variance analysis, index (SQI) was calculated assess at points. SOC, TN, AN contents significantly greater than those grassland, TP, AN, AK, SOC FL, FN, GC FP GO. Among them, highest reaching 2.74, 0.39, 47.27 g kg

Soil carbohydrates and glomalin-related soil proteins (GRSPs), as important components of organic matter, are the essential basis for maintaining aggregate stability. They interact with each other influence other. Exploring relationships mechanisms action between these two aggregates is great significance improving quality promoting sustainable development forest stands. This study focused on investigating composition (including >2, 2–1, 1–0.25, <0.25 mm fractions) stability (as indicated by mean weight diameter (MWD) geometric (GMD)) well aggregate-associated GRSP in Chinese fir plantations different stand types, including × Michelia macclurei (stand I), Mytilaria laosensis II), pure III). The results that 0–20 cm 20–40 layer, MWD GMD mixed stands were significantly (p < 0.05) higher than stand. contents also showed similar trends. suggests (especially macclurei) enhance soil. revealed although both contribute to formation large aggregates, PLS-PM analysis path coefficient was 0.840 0.576, while 0.134 0.398. Therefore, compared carbohydrates, easily extractable fraction GRSP) has a more pronounced effect finding provides scientific practical guidance enhancing productivity plantations.

Eucalyptus plantations suffer from soil degradation and reduced productivity due to short rotation cycles multiple generations of replanting. This study investigated the effects different thinning intensities (CK, 30%, 45%, 60%) on size composition, stability, distribution metal nutrient elements (K, Ca, Mg, Fe, Mn, Cu, Zn) aggregates in by collecting 0–20 cm samples using dry-sieving method separate into four sizes (>2 mm, 1–2 0.25–1 <0.25 mm). Our findings were as follows: (1) The majority comprised larger sizes, predominantly exceeding 2 mm diameter, which most abundant. (2) Compared with unthinned stands (CK) that thinned those 45% 60% demonstrated enhanced aggregate stability. (3) 30% had highest Mg Fe content, whereas contained levels Zn. Larger mm) harbored greatest quantities nutrients, smaller (<0.25 stored least. (4) primary determinants content soil’s pH organic carbon levels. (5) played a pivotal role influencing reserves within aggregates. Overall, this intensity not only impacts stability plantations, but also influences accumulation these aggregates, confirms significance macroaggregates reservoir for elements. To preserve enhance macroaggregates, it is recommended implement measures such reducing amount mechanical disturbance, increasing matter, optimizing stand structure, mitigating water erosion risks, promoting biological activity while conducting regular assessments
