Short Summary

This study analyzed the impacts of litter and slope gradient on soil moisture content (SMC) in a temperate deciduous broadleaf forest over two years, finding that both factors significantly influence SMC dynamics, with litter interception and slope affecting rainfall absorption and SMC response, which also varies seasonally and temporally due to litter decomposition.

Objective

• To analyze the impacts of litter and slope gradient on soil moisture content (SMC) in a temperate deciduous broadleaf forest, considering seasonal variations between foliage and non-foliage periods.

Study Configuration

• Spatial Scale: Mt. Jeombong, a specific location within a temperate deciduous broadleaf forest.
• Temporal Scale: From 2020 to 2021 (a 2-year period), categorized into foliage and non-foliage seasons.

Methodology and Data

• Models used: No explicit models were mentioned; the study appears to be based on field observations and analysis.
• Data sources: Field measurements of soil moisture content, rainfall, litter layer characteristics, and slope gradient.

Main Results

• Soil moisture content (SMC) was significantly influenced by both slope gradient and the litter layer.
• Gentle slopes exhibited higher rainfall absorption, leading to greater SMC.
• The litter layer intercepted rainfall, affecting the amount of water reaching the soil.
• The correlation coefficient (R²) between SMC increment and rainfall was lower in the non-foliage season (0.37–0.56) compared to the foliage season (0.72–0.84).
• Over time, the SMC response to rainfall increased in areas with thick litter accumulation, suggesting that litter interception gradually diminished due to decomposition.
• Spatial heterogeneity in the litter layer and slope gradient substantially influenced the supply of soil moisture from rainfall.

Contributions

• Provides empirical evidence on the combined and interacting effects of litter layer and slope gradient on soil moisture content in a temperate deciduous broadleaf forest.
• Highlights the seasonal variability and temporal changes in litter interception efficiency due to decomposition.
• Emphasizes the importance of considering spatial heterogeneity of these factors for a comprehensive understanding of soil moisture dynamics.
