摘　　要：南小河沟流域是黄河水利委员会西峰水土保持科学试验站开展黄土高塬沟壑区水土流失规律观测和水土保持试验研究的典型小流域。从1954年开始先后在南小河沟流域的塬面、坡面、沟道分别布设径流场,对高塬沟壑区典型小流域径流泥沙来源及水土保持单项治理措施效益进行定量观测与研究。本数据为1954-2018年南小河沟流域154个径流场观测数据集,观测要素包括降水量、径流量、泥沙量、土壤含水率。可为黄土高塬沟壑区水土流失规律研究、土壤侵蚀预测模型构建、水土保持措施配置提供科学、可靠和长期连续的观测数据。Nanxiaohegou watershed is one of the experimental basins used to study soil and water conservation in the gully regions of Loess Plateau by Xifeng Soil and Water Conservation Scientific Experimental Station of the Yellow River Conservancy Commission(hereinafter referred to as Xifeng Station).The establishment of Xifeng Station is approved in 1951.And Nanxiaohegou was selected as a comprehensive treatment experimental base in 1952.Runoff fields and precipitation stations have been set up since 1954.Long-term runoff and sediment yields from different runoff fields designed with different micro-topography,slopes,land cover types and treatment measures have been obtained.This dataset is a collection of observation data from 154 runoff fields in Nanxiaohegou Watershed from 1954 to 2018.The observation data includes precipitation,runoff,sediment volume,and soil moisture content.This dataset will provide scientific,reliable,and long-term observation data for studying the law of soil and water loss in gully regions of Loess Plateau,building a model for predicting soil erosion,and developing soil and water conservation measures.
