“…5 also reveals that the SOC content at 50-60 cm failed to follow the linear relationship. A similar trend was reported by Aminem et al (2014), which focused on the SOC content and its influencing factors in the P. schrenkiana forest on the north slope of the Tianshan Mountains. As reported in Wu et al (2009), the soil above 50 cm is the soil formed since 1995 when the "Grain for Green" program started.…”

The effect of land-use changes on soil carbon stocks has been an increasing concern in the context of global climate change. Through natural reforestation programs, abandoned cropland holds the potential of sequestering soil organic carbon (SOC) if the original forest could be recovered. In this study, we initially delineated the potential distribution of forest species on the north slope of the Tianshan Mountains using species distribution models. We then estimated the corresponding sequestration potential of SOC in the area delineated for reforestation. The deforestated area of a Picea schrenkiana forest converted to cropland (PSC) was defined by the potential and actual distributions of forest and cropland. The SOC contents of the forest and cropland soils were obtained through field sampling and laboratory analysis. We found that the area of the PSC was 26.77 × 105 ha, and the SOC loss (per unit area) derived from the conversion of forestland to cropland was 171.70 ± 28.20 Mg ha−1. The total SOC loss from the study area was 459.70 ± 75.49 Tg. This result implies that continuing the reforestation programs being implemented in the study area would increase SOC by the same amount. Additionally, we also estimated the total amount of carbon that would be sequestered in the aboveground and underground forest biomass on former cropland.

“…However, the increased VWC in natural wetlands would have dissolved more carbon dioxide, which might lead to a decrease in pH. (Liu et al, 2021). Similar experimental results were found in swamp wetland located in Zhejiang province, which was endangered by drought and human activities (Yang et al, 2022).…”

Land use conversion on river plain has profound impacts on soil characteristics and elemental stoichiometry. Four wetland types (Riparian lower‐beach wetland [RLW], Riparian higher‐beach wetland [RHW], Cultivated wetland [CW] and Mesophytic wetland [MW]) were selected in the lower Yellow River area to investigate the consequence of wetland type conversion on soil carbon (C), nitrogen (N) and phosphorus (P) stoichiometry. The results demonstrated that wetland conversion induced significant spatio‐temporal variations in soil C, N and P stoichiometry and physicochemical characteristics in soil. Frequent agricultural activities (fertilizer input) raised the nutrient content of natural wetland, particularly in surface soil (0–30 cm). Soil volumetric water content (VWC), soil bulk density (SBD), pH and soil enzyme activity varied significantly in different wetlands. Total carbon (TC) and total nitrogen (TN) contents in MW decreased with increasing soil depth (<40 cm layers), as did TN and total phosphorus (TP) contents in CW. On the other hand, TC, TN and TP contents in RLW and RHW did not change significantly with soil depth. However, the contents of TOC, and Fe/Al‐P, etc., varied among soil layers and among wetland types. Furthermore, the stoichiometric characteristics changed significantly in some soil layers, with mean values being less than the Chinese average. Statistically, significant positive correlations were determined between TC and TN (r = .56), TDC and TP (r = .62), N:P and pH (r = .57) (p < .05) and and pH (r = .66, p < .01). VWC was negatively correlated with pH (r = −.56, p < .05), while C/P was negatively associated with soil temperature (ST) and SBD (r = −.55, r = −.64, p < .05). TDC, IP, TN, Fe/Al‐P and ST were identified as the dominant factors, with the percentage of variance 41%, 20%, 12%, 9% and 6% respectively. These findings have a great scientific significance for the ecological conservation of wetlands in the lower Yellow River area.
