1945-1957年黄土丘陵沟壑区第三副区大柳树沟梁家坪径流场基本观测数据集

本数据集为1945-1957年黄土丘陵沟壑区第三副区大柳树沟梁家坪径流场基本观测数据。数据集包括径流场土壤含水率、降水及泥沙观测数据。大柳树沟梁家坪径流场是我国最早开始长系列观测的坡面径流场。主要对不同水土保持措施径流小区产生径流的次降水量、径流量、泥沙量进行观测，对比不同措施的减水减沙效益。径流场情况见径...

This dataset comprises basic observation data collected at the Liangjiaping Runoff Plot of Daliushougou, located in the third sub-region of the loess hilly-gully region, spanning the years 1945 to 1957. The dataset encompasses observation records of soil moisture content, precipitation, and sediment for the runoff plot. The Liangjiaping Runoff Plot of Daliushougou stands as one of the earliest slope runoff plots in China to carry out long-term serial observations. It mainly monitors the single-event precipitation, runoff volume and sediment yield of runoff plots under different soil and water conservation measures, and compares the water and sediment reduction benefits of various measures. Details regarding the runoff plot are available in the runoff...
