黄土高原地区水土流失对土地利用和降水变化的响应

Shuitu Baochi Xuebao
[目的] 为阐明不同降雨类型下各土地利用类型产流产沙规律,评估不同降雨类型下各土地利用类型的减流减沙效益。[方法] 基于黄土高原地区自然降雨条件下31个径流场连续2年(2015—2016年)的径流量和土壤流失量监测数据,探讨不同土地利用类型(农地、撂荒地、人工草地、自然草地、灌丛地、人工林地)的产流产沙特征,明确不同降雨类型下各土地利用类型的减流减沙效率。[结果] 年降雨尺度下撂荒地径流量与土壤流失量最大(30 mm, 86 t/hm2),人工林地最小(8 mm, 24 t/hm2 ...

紫色土丘陵区生物埂不同植被类型土壤分离水动力学特征

Shuitu Baochi Xuebao, 2019
野外采集紫色土区六棱型预制网格式护坡生物埂内不同植被类型原状土样，通过室内模拟细沟水槽（长4 m，宽0.12 m，深0.1 m）冲刷试验，探究不同植被类型影响下土壤分离能力与水动力学参数之间的关系。选择麦冬、韭菜2种生物埂类型，以单一网格式裸坡为对照，在3个坡度（15°，20°，25°）、5个流量（39.86，59.98，79.67，100.45，121.16 L/min）组合条件下进行冲刷试验。结果表明：生物埂内不同植被类型下土壤分离能力差异显著（P 对照（均值1.34 kg/（s·m2）） > 韭菜（
