摘　　要：土壤水分是土壤学与水文学等相关学科研究的重点领域和热门话题,是岩石圈—大气圈—生物圈—水圈中水分循环的关键环节。本研究从小区、坡面、流域、区域四个空间尺度探讨土壤水分时空分布格局及主要影响因子,发现各空间尺度土壤水分的研究侧重点及主控因子均不相同,因此提出了不同空间尺度上土壤水分的未来研究方向,为多方位、多角度、多视野探索土壤水分变异及拓展相关领域的研究提供理论依据。Soil moisture is a key field and hot topic in related disciplines such as soil science and hydrology,and a key link in the water cycle in the lithosphere-atmosphere-biosphere-hydrosphere.This study explores the spatial and temporal distribution patterns of soil moisture and the main influencing factors from four spatial scales of plots,slopes,watersheds,and regions.It is found that the research focus and main controlling factors of soil moisture at different spatial scales are different.The future research direction of soil moisture provides a foundation for multi-directional,multi-angle,multi-view exploration of soil moisture variability and the expansion of research in related fields.
