“…Soil pH was measured using a pH meter in a 1:2.5 soil-water dilution sample. Soil particle composition (clay, silt, fine sand, and sand) was measured by a laser particlesize analyzer, and soil organic matter (SOM) and plant C content was measured using a potassium dichromate oxidation method [26]. Soil and plant total phosphorus (TP) content was measured with the colorimetric method using ammonium molybdate after acid digestion.…”

“…The TP content in forestland and farmland was higher than grassland and shrubland. In the Nianchu River Basin, P content was related to soil [26], and it can be shown that forestland and farmland soil P content was higher than grassland and shrubland. Grasslands had the lowest TP content, as discovered by Li et al, 2016, [34].…”

Land use types can cause changes in soil chemical characteristics, such as altering soil C, N, and P contents and distribution. The aim of this study was to investigate the status of soil C, N, P and other nutrient contents and their stoichiometric ratios in the terrestrial ecosystem of Nianchu River Basin, Tibet. A total of 102 sample plots with 306 soil samples and 102 plant samples were investigated in August 2021 along the Nianchu River basin by selecting four land-use types: grassland, shrubland, forestland, and farmland. The soil’s basic physical and chemical properties (soil organic matter (SOM), total nitrogen (TN), total phosphorus (TP), alkaline nitrogen (AN), available phosphorus (AP), pH, and soil particle composition) were examined at each sampling point, and the stoichiometric characteristics of C, N, and P of the soils were analyzed using one-way analysis of variance (ANOVAs). The results revealed that the C and N contents of shrubland were significantly lower than those of grassland, forestland, and farmland, with farmland having the highest P content. For all land types, C:N increased with increasing soil depth, while C:P and N:P decreased with increasing soil depth. PCA and RDA analyses revealed that soil texture and pH had an impact on soil C, N, and P contents, as well as stoichiometric ratios.

“…Soil, as the basis for supporting vegetation growth, has strong explanatory power in terms of the variation in ESs of ESB2 based on its texture. The wide variation in soil texture across the ESB2 area may limit the supply of water and nutrients required for vegetation growth in different areas (Jiang et al, 2020b;He et al, 2021). Landscape composition factors also represent certain human activities.…”

The degradation of ecosystem structure and function on the Qinghai-Tibet Plateau is the result of a combination of natural and anthropogenic factors, with landscape change driven by global change and human activities being one of the major ecological challenges facing the region. This study analyzed the spatiotemporal characteristics of ecosystem services (ESs) and landscape patterns in eastern Qinghai province (EQHP) from 2000 to 2018 using multisource datasets and landscape indices. Three ecosystem service bundles (ESBs) were identified using the self-organizing map (SOM), and changes in ecosystem structure and function were analyzed through bundle-landscaped spatial combinations. The study also explored the interactions between ESs and natural and human factors using redundancy analysis (RDA). We revealed an increase in total ecosystem service in the EQHP from 1.59 in 2000 to 1.69 in 2018, with a significant change in landscape patterns driven by the conversion of unused land to grassland in the southwest. Forestland, grassland, and unused land were identified as important to the supply of ESs. In comparison to human activities, natural environmental factors were found to have a stronger impact on changes in ESs, with vegetation, meteorology, soil texture, and landscape composition being the main driving factors. However, the role of driving factors within different ESBs varied significantly. Exploring the response of ecosystem services to changes in landscape patterns can provide valuable insights for achieving sustainable ecological management and contribute to ecological restoration efforts.

“…Several methods of SQ evaluation have been developed, among which the soil quality index (SQI) is the most commonly used (Askari & Holden, 2014; Paul et al., 2020; Rahmanipour et al., 2014). This index has been applied to evaluate the effects of different managements on SQ even crop productivity in various systems (e.g., Amorim et al., 2021; Askari & Holden, 2014; He et al., 2021) for its quantitative flexibility and accuracy. The SQI combines soil physical, chemical, and biological properties into a single indicator through three steps: indicator selection, indicator scoring, and integration of scores into an index (Andrews et al., 2002; K. Li et al., 2022; Wander & Bollero, 1999).…”

Biological conservation measures are better than engineering conservation measures in improving soil quality of eroded orchards in southern China

Both biological and engineering measures have proven to be effective soil and water conservation practices for eroded environments, whereas how the soil quality varies with them remains unclear. In this study, we measured soil properties in the 0-to-100-cm soil layer of eroded orchards in southern China after 17-yr of application of different conservation measures. The purpose of the experiment was to examine the effect of biological (grass planting, intercropping) and engineering measures (terrace) on the soil quality of eroded orchards. We selected an orchard plot with traditional clean-tillage as control. In comparison, soil pH, organic carbon, total phosphorus, microbial carbon, available potassium, and available microelements contents increased significantly in orchards with biological measures, and the improvements were more dramatic in orchards planting grass in strips. However, biological measures significantly reduced the mean weight diameter of aggregates. Engineering measures significantly increased the soil pH of orchards but decreased the contents of available iron and available manganese. The soil quality index (SQI)
