本数据集为2025年黄土丘陵沟壑区第一副区桥沟流域不同地貌类型径流场土壤含水率观测数据。桥沟流域位于陕西省榆林市绥德县，流域面积0.45平方公里，流域形状为叶面状，长宽为1.4KM和0.32KM,相对高差132m,沟壑密度5.4km²，属于裴家峁沟（无定河一级支流）的一级支流。本数据集对桥沟8个不同地貌类型径流小区土壤含水量进行观测，每天采集土壤样品，降水日对样品进行测定，没有降水则不作测定。径流场基本情况见《桥沟不同地貌类型径流场情况说明》。主要观测指标有：场号、测次、取样日期、测点土壤含水率（％）、两测次间降水量（mm）。每月固定观测3次（1号、11号、21号），雨前雨后加测。", "ds_source": "

This dataset is the observation data of soil moisture content in runoff fields of different landform types in the Qiaogou Basin, the first sub-district of the Loess Hilly-Gully Region in 2025. The Qiaogou Watershed is located in Suide County, Yulin City, Shaanxi Province, with a drainage area of 0.45 square kilometers. The drainage area is leaf-shaped, with a length and width of 1.4KM and 0.32KM, a relative height difference of 132m, and a gully density of 5.4km2. It belongs to the first-class tributary of Peijiamaogou (a first-class tributary of Wuding River). This dataset observes the soil water content of 8 runoff plots with different landform types in Qiaogou. Soil samples are collected every day and measured on precipitation days. No measurement is made if there is no precipitation. For the basic information of the runoff field, see the \"Description of Runoff Fields of Different Landforms in Qiaogou\". The main observation indicators include: site number, measurement times, sampling date, soil moisture content at the measurement point ( %), and precipitation between two measurement times (mm). Make regular observations three times a month (No. 1, No. 11, and No. 21), with additional measurements before and after rain.", "ds_time_res": "minutes, days, times", "ds_acq_place": "Qiaogou watershed, Suide County, Yulin City, Shaanxi Province", "ds_space_res": "", "ds_projection": "", "ds_process_way": "
