气候变化改变空气温度、降水量和降雨模式，从而影响土壤环境，包括土壤含水量和温度。气候变化对土壤环境的影响因地区而异。因此，重要的是要评估气候变化对土壤环境的影响，利用气象和土壤信息的具体到每个地区。日本岐阜县面积大，地形多样性丰富。本研究旨在阐明气候变化对岐阜县平原和山区土壤环境的影响。利用HYDRUS-1D和农业气象网格数据计算了当前（2011 -2020年）和未来（2091-2100年）的土壤温度、含水量和积雪深度。分析预测未来土壤温度将上升3摄氏度。平原区土壤温度的升高幅度大于山地区。未来平原样地土壤含水量增加（增加0.01× 10 - 3 m3 m-3），山地样地土壤含水量减少（减少0.67× 10 - 3 m3 m-3）。这些结果可能会有所不同，这取决于所选择的全球环流模式。山区样地冬季降雪量较大，影响土壤含水量。平原土壤温度对气候变化的敏感性高于山地，山地土壤水分对气候变化的敏感性高于平原。本研究揭示了气候变化对两个地区的影响，今后我们将把分析范围扩大到整个岐阜县。
Climate change alters air temperature, precipitation, and rainfall patterns, thereby affecting the soil environment, including soil water content and temperature. The impact of climate change on soil environment varies from region to region. Therefore, it is important to evaluate the impacts of climate change on the soil environment using meteorological and soil information specific to each region. The Gifu Prefecture, Japan, has a large area and rich topographical diversity. This study aimed to elucidate the impact of climate change on the soil environment in the plain and mountainous regions of Gifu Prefecture. The present (2011–2020) and future (2091–2100) soil temperature, water content, and snow depth were calculated using HYDRUS-1D and Agro-Meteorological Grid Square Data. The analysis predicted an increase in soil temperatures by 3 C in the future. The increase in soil temperature at the plain site was larger than that at the mountainous site. The future soil water content in the plain site increased (by 0.01× 10− 3 m 3 m− 3) and that in the mountainous site decreased (by 0.67× 10− 3 m 3 m− 3). These results may differ depending on the global circulation model selected. The mountainous site indicated heavier snowfall in winter, affecting the soil water content. The plain site was more sensitive to climate change than the mountainous site with respect to soil temperature, and the mountainous site was more sensitive to climate change with respect to soil moisture. This study revealed the impacts of climate change on two regions, in the future we will expand our analysis to cover the entire Gifu prefecture.
