Special Issue Information

Dear Colleagues,

Forest soils store vast amounts of organic carbon, potentially more than above-ground biomasses in many ecosystems. Understanding the mechanisms governing soil carbon storage and the threats posed by climate change is fundamental to predicting future carbon dynamics and developing sustainable land management practices.

We now have a relatively comprehensive understanding of the process of soil carbon dynamics. The size of a soil C pool depends on the balance between the input of plant material (litter, roots, and woody debris) and SOC mineralization. The stability of carbon in forest soils depends on various factors such as temperature, moisture levels, microbial activity, and soil type. However, climate change increases the uncertainty of this complex process. Therefore, this Special Issue aims to collect recent findings from different geographic locations to improve our ability to understand and predict the evolution of forest soil C accumulation and SOC stability under a changing climate. 

You are welcome to submit your research to this issue. All topics related to forest soil carbon are encouraged, including the following:

  • New technologies in forest soil carbon research;
  • Climatic effects on soil C storage and stability;
  • Soil carbon fractions and formation;
  • Temperature sensitivity of C mineralization;
  • Forest management and climatic changes.

Topsoil organic carbon (SOC, 0–20 cm) is crucial for terrestrial carbon stocks and the global carbon cycle. This study integrated field survey data, re-analysis climatic data, and remote sensing-derived environmental factors to examine SOC distribution and its drivers across forest types on Hainan Island using machine learning models and statistical analysis. The results showed that univariate analysis had limited explanatory power for forest SOC, with terrestrial plantations exhibiting significantly lower SOC than mangroves and natural forests. For mangroves, vapor pressure deficit (VPD) was the most influential factor, followed by precipitation (PRE), the normalized difference vegetation index (NDVI), and forest age; meanwhile, for terrestrial forests, VPD, altitude, PRE, and NDVI were vital drivers. The optimal models demonstrated relatively stronger predictive performance (R2 = 0.71 for mangroves; R2 = 0.81 for terrestrial forests). Mangroves showed higher average SOC (27.91 g/kg) than terrestrial forests (15.82 g/kg), while higher concentrations in the central–western region were attributed to natural terrestrial forests. This study reveals the spatial variation patterns of forest SOC and its environmental regulation mechanisms on Hainan Island, providing important references for forest carbon stock management and environmental protection.
