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 ...

1970—2020年秦岭南北夏季昼晴夜雨强度变化趋势及其影响因素

Shuitu Baochi Xuebao
[目的] 在陕西3大地理单元中,秦巴山区土壤侵蚀强度仅次于黄土高原。明晰秦岭南北夏季昼晴夜雨强度与气候变暖的响应关系,对区域土壤侵蚀防治具有重要的意义。[方法] 基于1970—2020年逐日降水数据,辅以BG分割法、经验正交函数和Lasso回归等方法,对秦岭南北地区夏季昼晴夜雨强度时空变化特征及其影响因素进行分析。[结果] 1970—2020年,秦岭南北夏季昼晴夜雨强度呈现显著增加趋势。空间上,秦岭南北夏季昼晴夜雨强度主导模态为全区一致增强。其中,1 000 m以下的谷地和平原区 ...
