“…Soils store more organic carbon than exists in the vegetation and atmosphere combined (Jobbágy & Jackson, 2000), and a slight fluctuation in soil organic carbon (SOC) may alter the terrestrial ecosystem carbon cycle and climate (Kooch et al, 2022). Forest soils, in particular, have well‐developed organic layers that store a considerable amount of organic carbon.…”

Understanding the dynamic relationships between soil organic carbon (SOC) and stand age are essential to quantify and predict the terrestrial carbon sequestration potential. However, the spatial patterns in the response of rubber plantation SOC to stand age and their driving factors remain unclear. Based on SOC and its components measurement at different soil depths (0–40 cm) in rubber plantations under five different age classes (0–5, 5–10, 10–20, 20–30, and >30 years) in three major rubber cultivation regions in China, distribution pattern and controlling factors of SOC were investigated. We found that SOC and its components showed significant spatial variability vertically with soil depth and laterally across sampling sites. SOC contents in three major rubber cultivation regions range from 4.48 to 20.13 g kg−1 at a depth of 0–40 cm. Among the sampling sites, Jinghong had the highest SOC content at a depth of 0–10 cm (20.13 g kg−1). On a large‐scale, the relationship between SOC and stand age in rubber plantations did not show a consistent pattern among different sampling sites. Additionally, annual rainfall, soil moisture content, and soil pH had a stronger impact on SOC in rubber plantations compared to stand age. The results indicated that the spatial variability of SOC in rubber plantations with stand age could be influenced by specific soil properties and climate‐related variables at each sampling site. This study emphasized the significance of conducting multi‐site, multi‐scale studies to enhance our understanding of SOC dynamics and its influencing factors, and help to more accurately predict the dynamic changes of soil carbon storage in rubber plantations.

“…Forest SOC are influenced by a variety of biotic, abiotic, and anthropogenic factors, either independently or in combination. Therefore, identifying the primary factors that affect the spatial distribution of forest SOC characteristics often requires specific case studies (Kooch et al, 2022).…”

“…al., 2021), and in North Asia, warming is accelerating the accumulation of vegetative carbon(Liu et al, 2022)3. Appropriate grazing management may be a critical control in dryland rangelands to maximize the provision and control of ecosystem carbon services(Onatibia et al, 2015); the level of household residential a uence is also an important driver of household carbon footprint(Feng et al, 2021); arti cial treatment of dryland straw is an effective channel for increasing soil organic carbon(Li et al, 2016); and soil organic carbon is negatively affected by land use change in semi-arid environments in northern Iran(Kooch et al, 2022); land occupation by solar power plants has also become one of the most popular ways to achieve global carbon neutrality targets in Korea(Kim et al, 2022); and in Bangladesh, the development of rice-vegetable land farming practices has led to an increase in soil carbon stocks with soil depth(Munny et al, 2021). It is clear that there is no single driver for the evolution of carbon stocks, but they are all dependent on the diversity of surface land use practices, which directly or indirectly exert their potential in uence on carbon stocks.…”

Terrestrial ecosystems are significant carbon sinks and are crucial for understanding the regional and global carbon cycles, energy flow, and climate change. As land use change is a significant factor affecting ecosystem carbon stocks, studying it is essential to comprehending the evolution of regional carbon sink functions and achieving sustainable development goals. The drastically diverse land use patterns in each of the study area's functional areas resulted in significant differences in carbon stocks between them. This study explores the evolution traits of carbon stocks based on land use data and their driving mechanisms in Chongqing during the past 30 years by using spatial analysis, the InVEST model, and geographic probes. The results demonstrate the significant change in land use change in the study area, which led to a 5.1078Tg decrease in total carbon stock, a decline of 1.5%. The main pathway for carbon loss pathway in the evolution of carbon stock is the conversion of cropland to construction land, and the primary carbon compensation pathway is the conversion of grassland and cropland to forest land, with a spatial distribution characterized by "higher in the whole area and obvious local differences". The degree of land use contributes most to the evolution of carbon stocks. Moreover, the interaction of pairwise factors played a more important role in affecting the evolution of carbon stocks than did each factor individually. The case study in this paper shows that land use change is a significant driving mechanism for the evolution of carbon stock, and the development of a driving model theory is appropriate for deciphering the trajectory of carbon stock evolution and offering research suggestions for other regions.
