间歇性降雨对黄土坡地水土养分流失的影响

Shuitu Baochi Xuebao, 2018
坡面水土养分流失是研究农业非点源污染方面的核心问题，涉及土壤侵蚀、坡地水文和环境治理等方面的内容。以黄土坡地为研究对象，利用人工降雨模拟试验，分析间歇降雨时坡地产流-入渗-土壤侵蚀过程，以及通过预先在坡地喷施养分（NH4+-N、NO3--N、PO43--P），研究间歇降雨时坡面水土流失以及土壤溶质的迁移规律。试验采用针孔式人工模拟降雨器进行模拟降雨，对试验坡地间歇性进行3次降雨，雨强恒为100 mm/h，每次降雨历时60 min，降雨间隔时间60 min。结果表明：（1）3次降雨的初始含水率不同 ...

连续性与间歇性降雨下土壤结皮与入渗的关系模拟

Shuitu Baochi Xuebao
[目的] 为探究连续性和间歇性降雨条件下土壤结皮与入渗性能间的变化关系。[方法] 选取3种典型耕作层黄土,通过室内模拟降雨试验,分析不同降雨条件下土壤结皮强度和黏结力与入渗性能的关系。[结果] (1)入渗性能随连续性降雨历时及间歇性降雨场次的增加而减小;同等降雨历时和降雨强度下,间歇性降雨的减渗效应高于连续性降雨。(2)土壤结皮强度和黏结力随连续性降雨历时和间歇性降雨场次的增加而增加;褐土和黑垆土的入渗性能与结皮强度和黏结力呈显著线性相关(p＜0.05),连续性降雨历时越长、间歇性降雨场次的越多 ...
