“…This results in a gradual decrease in δD values of meteoric water, with a decline rate of -0.26‰/100m with altitude [12]. The δD value of meteoric water in this study is -126‰, sourced from the rainwater data of the Lhasa Meteorological Station [10].…”

The Woka-Cuona rift zone, situated in the easternmost portion of southern Tibet, displays complex geological conditions. It consists of three distinct grabens or half grabens, spanning the Himalayan and Gangdese terranes from south to north. Examining the distribution patterns and genetic mechanism of the geothermal system in the Woka-Cuona rift zone holds significant guidance for studying the genetic mechanisms of geothermal systems and the production and utilization of ge-othermal resources in the rift zones of southern Tibet. Based on the geological conditions of the study area, the mechanism of rift formation and the distribution characteristics of geothermal water in the three distinct grabens were analyzed through data collection, ground surveys, geochemical analysis, and isotope analysis. Alongside topographic, drainage, and structural features, the Woka-Cuona rift zone was subdivided into four zones from north to south - Woka, Qiongduojiang, northern Cuona, and southern Cuona grabens. Additionally, the study investigated the geochemical char-acteristics, recharge sources, and water-rock interactions of geothermal water in different zones, providing a scientific foundation for subsequent geothermal energy production.

“…While the diversity and evenness of soil fauna were not significantly different between sampling months (P > 0.05), the differences in evenness were significant (P < 0.05), indicating that different sites in the Poyang Lake region had significant effects on soil fauna diversity, while the date of sampling only significantly impacted soil fauna evenness. Previous studies have shown that soil fauna composition is also related to the complexity of soil ecosystems and is strongly influenced by soil environmental factors (Lu et al, 2013;Yin et al, 2015). This study only explored the relationship between the structure and diversity of soil fauna at different locations of Poyang Lake beach wetlands; the reasons for the changes should be further studied in combination with soil environmental factors.…”

“…However, the number of functional groups was stable and was not significantly affected (P > 0.05). We believe that the functional groups were stable in the same habitat, but the soil fauna community was affected by soil properties (Scheunemann et al, 2010;Sylvain et al, 2014;Yin et al, 2015;Korboulewsky et al, 2016). The dominance of the Acarina in the wetland environment and the ratio of Acari to Collembola (A/C > 1) are characteristics of wetlands (Wu et al, 2008).…”

We examined the soil fauna community composition and structure of Poyang Lake beach wetlands using the modified Tullgren and Baermann methods during September and December 2015. A total of 3755 individuals were obtained from 2 samplings, which were found to belong to 7 classes, 8 orders, 3 suborders, and 17 families. Among these, the Oribatida, Prostigmata, Nematoda, and Onychiuridae were dominant. The functional groups of soil animals included omnivores, saprozoics, predators, and phytophages. Analysis results of the soil fauna composition and diversity showed that the soil animals were mainly concentrated at the 0-10 cm depth, presenting as a significant surface convergence phenomenon. The numbers of individual soil animals differed significantly between sampling sites (P < 0.05), with the beach wetland in Lianhu Township having the highest numbers of individuals and groups. The effect of water level variability on numbers of soil animals was not significant (P > 0.05). Habitat type and sampling time both had highly significant effects on diversity and evenness (P < 0.01), and significant effects on species richness (P < 0.05). During water level changes in Poyang Lake, the individual number, group number, and diversity of the soil animals were closely linked to the sampling site. These results provide basic data for further studies on soil fauna ecology in Poyang Lake beach wetlands.

“…Soil is an important component of terrestrial ecosystems, providing the mineral nutrient elements for plant growth, especially carbon (C), nitrogen (N), and phosphorus (P), which are the main components of soil nutrients, play a crucial role in ensuring ecosystem health and its nutrient cycling [1][2][3]. Ecological chemometrics, as a science to study the energy balance and multiple chemical element balance of biological systems, has become a new method to study the change pattern and coupling relationship of nutrient elements such as C, N and P in the ecosystem [4][5][6][7][8].…”

The vertical distribution and stoichiometry characteristics of soil organic carbon (SOC), total nitrogen (TN), total phosphorus (TP) of soil profiles along an altitude gradient were investigated in Luofu Mountain, Guangdong. A total of ten sites at different altitude gradients in Luofu Mountain were selected and soil genetic horizon samples were collected. Soil physic-chemical properties, such as bulk density, soil particle-size composition, pH, SOC, TN, TP, total iron oxides (Fe t ), free iron oxides (Fe d ), amorphous iron oxides(Fe o ), CEC, etc, were
