本数据集为2011-2020年黄土丘陵沟壑区第三副区罗玉沟流域径流场数据。2006年在罗玉沟试验场集中布设不同坡度、不同措施的17个坡面径流小区，2008年开始观测；2016年改造了之前项目布设的17个径流小区，增加布设了具有地区代表性的林地（刺槐林）、经济林（樱桃）径流小区各1个，自2018年开始观测。径流场汛期观测，观测降水量、径流、泥沙、地表植被、土壤含水率等参数指标。本数据集包括径流小区基本情况表、逐次径流泥沙测验成果表、径流小区土壤含水量人工观测成果表。

<pre><code> <pre><code> &lt;pre&gt;&lt;code&gt; &amp;lt;p&amp;gt;This data set is the runoff field data of Luoyugou watershed in the third sub region of Loess Hilly and gully region from 2011 to 2020. In 2006, 17 slope runoff plots with different slopes and different measures were set up in Luoyugou experimental field, and the observation was started in 2008; in 2016, the 17 runoff plots set by the previous project were reconstructed, and one runoff plot with regional representative forest land (Robinia pseudoacacia forest) and economic forest (Cherry Blossom) were added, and the observation began in 2018. Runoff field observation in flood season mainly includes precipitation, runoff, sediment, surface vegetation, soil moisture content and other parameters. Precipitation is observed by rain gauge; runoff of catchment basin is observed manually; sediment concentration is calculated by artificial sampling and replacement method, and then sediment yield is calculated; vegetation coverage is observed by visual estimation method, canopy closure is observed by needle method; soil moisture content is measured by manual observation, soil moisture content is measured by drying method, and observation is started in 2018. This data set includes the basic information table of runoff plot, the result table of successive runoff and sediment measurement, and the manual observation result table of soil moisture content in runoff plot. &amp;lt;/p&amp;gt;\n <pre><code> <pre><code> &lt;pre&gt;&lt;code&gt;\nRain gauge is used to observe precipitation; catchment basin is used to observe runoff; sand sample is taken manually and sand content is calculated by replacement method to calculate sediment yield; vegetation coverage is observed by visual estimation method, canopy density is observed by needle method; soil moisture content is observed by manual observation and soil moisture content is measured by drying method.
