Comparing time-series characteristics of soil moisture with different land-use in rural areas of Gangwon State

초록

Efficient water resource management has gained increasing significance in light of the rising frequency of droughts attributed to climate change. This study focuses on unraveling the variation and time series characteristics of soil moisture in relation to land use, a crucial factor influencing groundwater recharge. Soil moisture content measurements were conducted in rural areas with diverse crop cultivation, and subsequent time series analyses were performed. Auto -correlation analysis, spectral density analysis, and cross -correlation analysis were employed, utilizing precipitation and temperature data as inputs. The findings revealed a short-term increase in soil moisture content immediately following precipitation, followed by a gradual decline. Monthly auto -correlation patterns exhibited similarity, with amounts of variation contingent upon land use and depth. Cross -correlation analysis showed a swift positive impact of precipitation on soil moisture content, while temperature exerted a relatively slow negative effect. This study contributes valuable insights into understanding the dynamics of soil moisture in agricultural landscapes, aiding in the development of effective water resource management strategies.
