<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;

Rain 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.
