2000-2010年黄土高塬沟壑区南小河沟流域径流场数据集

本数据集为2000-2010年南小河沟流域径流场观测数据，观测要素有产生径流的次降雨量、次径流量、次泥沙量、土壤含水量、被覆度。次降雨量观测用该站点设的专用雨量站或借用临近雨量站的SM1型雨量器或自计雨量计进行雨量摘录；径流、泥沙采用径流桶（池）人工观测。土壤含水率采用人工取土烘干法观测，被覆度采用人工目测。

This dataset comprises runoff plot observation data collected in the Nanxiaohegou Basin from 2000 to 2010. The observed variables include event rainfall amount triggering runoff, event runoff volume, event sediment yield, soil moisture content and vegetation coverage. Event rainfall amount was recorded using either the dedicated rain gauge station installed at the site, or the SM1-type rain gauge or automatic rain gauge borrowed from adjacent rain stations for rainfall data extraction. Runoff volume and sediment yield were manually monitored using runoff barrels (ponds). Soil moisture content was measured via manual soil sampling and gravimetric drying method, while vegetation coverage was assessed through manual visual inspection.
