本研究は、イリノイ州の高台林と氾濫原林における土壌有機炭素（SOC）ストックとその垂直分布を比較した。結果、氾濫原林のSOCストック（100.7 Mg/ha）は高台林（80.1 Mg/ha）より有意に高いが、垂直分布パターンに差はなかった。これらの知見は森林管理と気候変動緩和戦略に科学的根拠を提供する。
English
This study compares soil organic carbon (SOC) stocks and vertical distribution in upland and floodplain forests in Illinois. Floodplain forests had significantly higher total SOC stocks (100.7 Mg/ha) than upland forests (80.1 Mg/ha), but no difference in vertical distribution. Findings provide scientific basis for forest management and climate mitigation.

📄 Abstract（原文）
Soil organic carbon (SOC) is a key indicator of soil health, fertility, and ecosystem productivity. It plays a central role in nutrient cycling, water retention, soil structure formation, and microbial activity, while also contributing to climate regulation through carbon sequestration. Increasing SOC enhances soil resilience to erosion and drought, making it essential for sustainable land management. In forest ecosystems, understanding SOC dynamics is critical for developing science-based policies and management strategies aimed at climate change mitigation and sustainable resource use. However, comparative information on SOC stocks between upland and floodplain forests remains limited. In this study, SOC stocks and their vertical distribution were investigated in upland and floodplain forests along Thorn Creek in northeastern Illinois. Soil samples were collected at three depths (0-15, 15-30, and 30-45 cm). Soil organic carbon concentrations were determined using the Walkley-Black chromic acid wet oxidation method, and soil bulk density was measured using metal core sampling cans to calculate SOC stocks. Results showed that total SOC stocks were significantly higher in floodplain forests (100.7 Mg ha⁻¹) than in upland forests (80.1 Mg ha⁻¹). However, no significant differences were observed in the vertical distribution pattern of SOC along the soil profile between the two forest types. Soil water content was generally higher in floodplain forests than in upland forests, although the difference was not statistically significant. These findings improve our understanding of SOC storage across contrasting forest types and provide a scientific basis for forest ecosystem management and climate change mitigation strategies.
