sediment box

A dual-box system, consisting of a feeder box, located at up-slope, and a test box, located at down-slope was used to quantify impacts of runoff and sediment from up-slope on rill hydraulic parameters under different rainfall intensities of 50,90 and 130 mm/ h.

利用供沙土槽和细沟土槽双土槽径流小区系统，定量分析了粘黄土陡坡地在50、90和130mmh降雨强度下上方来水来沙对坡下方细沟水流水力学参数变化的影响。

Loess Hill Slope Erosion and Sediment Yield Process Using A Dual Box System

基于双土槽试验研究的黄土坡面侵蚀产沙过程

A dual box system ( one is rill box and the other is feeder box) with 15 gradient and clay loess is used to quantify effects of runoff and sediment from up slope on down slope rill erosion and sediment under different sediment concentrations and rainfall intensities.

利用双土槽系统径流小区（供沙土槽和试验土槽），定量研究了不同上方来水含沙量和不同降雨强度下15°坡面上方来水来沙对坡下方细沟侵蚀产沙过程的影响。

Simulated rainfall and text box are used to quantify impacts of straw cover amount and stubble height on volume and processes of Runoff-sediment-yield. Probe into the effect and mechanism of conservation tillage reduce soil and water loss. The main results are as follows: 1.

本论文利用模拟降雨方法和土槽径流小区系统，定量分析秸秆覆盖和留茬高度对产流产沙量和产流产沙过程特征的影响，探讨了保护性耕作减少水土流失的作用与机理。
