data for "Reduced Soil Moisture in Edge Zones along Deep-Cut Channels of Rainfed Agricultural Plateaus"

Edge zones in overbank areas along deep-cut channels, on rainfed plateaus, constitute vital farmlands in land-scarce agricultural regions. Soil moisture (SM), a critical constraint of local productivity, is typically lower in these zones than in the inner zones farther from the channels. However, to date, spatiotemporal dynamics of reduced SM in edge zones remain unquantified along deep-cut channels. Measurements of hourly SM were taken at 10, 40, and 70 cm depths, across three sites (at 3.5m, 7 m, and 11.5 m from the channel edge), during the 2023-2024 growing season of apple trees in the Weibei rainfed Plateau.雨养高原深切河道岸带漫滩区域的边缘地带，是土地资源匮乏的农业区的重要耕地资源。土壤湿度（Soil Moisture，SM）是制约当地农业生产力的关键限制因子，这类边缘地带的土壤湿度普遍低于远离河道的内部区域。然而迄今为止，沿深切河道分布的边缘地带土壤湿度降低的时空动态特征仍未得到量化解析。本研究于渭北雨养高原的苹果树2023-2024生长季期间，在距河道边缘3.5m、7m及11.5m的三个采样位点，分别于10cm、40cm、70cm的土层深度开展了逐小时土壤湿度监测。
