本数据集为1986-1990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，属于裴家茂沟（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1986-1990年情况说明》。主要监测指标有：\"场号\"、测次、取样日期、\"测点土壤含水率（％）取样深度0-10cm）\"、\"两测次间降水量（mm）\"、月日。", "ds_source": "

In this data set, the soil water content of eight runoff plots with different geomorphic types in Qiaogou was observed. Soil samples were collected every day, and the samples were measured on the day of precipitation, but not on the day of no precipitation. The basic situation of runoff field is shown in the description of runoff field of different geomorphic types in Qiaogou from 1986 to 1990. The main monitoring indicators include: field number, measurement times, sampling date, \"soil moisture content (%) sampling depth 0-10cm\", \"precipitation between two measurements (mm)\", month and day.

When the intermittent time of precipitation is more than 15 minutes, it is observed as two times of precipitation before and after the interval. When the intermittent time is less than 15 minutes, it is recorded as one-time precipitation observation. If one-time precipitation crosses 8 hours and 20 hours, it should be measured at 8 hours and 20 hours. Dsj2 type adopts 24 section system for flood season observation. In case of failure of self recording rain gauge, the observation data of ordinary rain gauge is used for supplement.
