土壤水分条件在崩岗沟的形成过程中起着重要的作用，但由于缺乏高频率的连续野外观测，我们仍然处于了解不同降雨事件后坡面土壤水分变化的早期阶段。基于2017 - 2019年对广东省五华县典型崩岗沟坡面土壤水分的连续多深度观测，研究了不同坡向和坡位土壤水分动态对降雨事件的响应。调查了植被特征和土壤性质，计算了土壤贮水量。结果表明，土壤水分的动态和贮量随坡向、坡位和植被覆盖度的不同而不同。阳坡土壤水分对强降雨事件的响应时间短于阴坡，土壤贮水量显著低于阴坡（p
Soil water conditions play an important role in the formation of a collapsing gully, but we are still at the early stages of understanding how the soil water changes on the slope after different rainfall events due to a lack of high-frequency continuous field observations. This study aimed to reveal the response of soil water dynamics to rainfall events for different slope aspects and positions based on continuous multi-depth observations of soil water on a typical collapsing gully slope from 2017 to 2019 in Wuhua County, Guangdong Province, China. The vegetation characteristics and soil properties were investigated, and the storage of soil water was also calculated. The results showed that the dynamics and storage of soil water varied with the slope aspect, slope position and vegetation cover. The response time of the soil water to intensive rainfall events on the sunny slope was shorter than that on the shady slope, while soil water storage in the sunny slope was significantly lower than in the shady slope (p
