采用运动波理论和两次改进后的Green-Ampt入渗模型建立了坡面降雨入渗产流的动力学模型,并得到了实验资料的良好验证。运用该模型研究了简单坡面上降雨入渗产流的动力学规律,分析了雨强、土壤初始含水量、渗透系数、坡面阻力,以及坡长、坡度等因素对坡面产流过程的影响规律 ...

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
[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 ...

目的为探究细沟侵蚀及其形态特征的变化规律和横断面分布特征。方法通过室内人工模拟降雨试验和三维激光扫描技术,分析不同降雨强度和坡度条件下细沟侵蚀产流产沙和细沟形态分布特征。结果1)降雨强度增大时,坡面产流产沙增幅显著,90 mm/h降雨强度时,细沟侵蚀量对总侵蚀量的贡献率达90%以上。2)细沟宽度、深度和细沟割裂度受降雨强度的影响明显,且均呈不同程度的增加,细沟割裂度、细沟最大深度与细沟侵蚀量呈极显著正相关。3)细沟横断面沿坡向变化较大,沟壁崩塌现象明显,60 mm/h降雨强度时细沟横断面多呈“窄浅 ...
