[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 ...

针对单一径流调控措施难以得到较好水土保持效果的问题,本研究通过天然降雨径流、产沙的试验定位观测,对几种措施复合后的次降雨径流、产沙的调控率,及对作物产量的影响做了分析。研究表明:复合措施可以有效地对坡面径流、产沙进行调控,减少坡面径流量和产沙量90%以上,同时提高农作物的产量10%以上。复合措施因其优异的径流、产沙调控能力,增产明显,成本低廉,实施简便 ...
