不同坡形坡面径流流速时空分异特征研究

Shuitu Baochi Xuebao, 2007
通过室内模拟降雨试验分析了不同坡形坡面径流流速的时空分异特征,研究结果表明:同雨强、同坡度条件下,直线形坡的坡面流速最大,凸形坡的其次,凹形坡的最小,并且在同坡形条件下,坡面流速随雨强、坡度的增加而增加。另外,不同坡形坡面径流流速在空间上也存在一定的差异,坡面径流流速基本上沿着坡面向下逐渐增大,并且坡面上各段流速随坡度、雨强的增大而逐渐增大。

黄绵土坡耕地磷素迁移与土壤退化研究

Shuitu Baochi Xuebao, 2003
坡地水土流失是导致区域土壤质量退化与土地生产力下降的重要原因。采用野外天然降雨-径流小区试验法,初步研究了黄土高原黄绵土休闲坡耕地一次轻度侵蚀(侵蚀量410～435t/km2)降雨前后土壤质量的退化特征。试验结果表明,降雨侵蚀前后坡地表层(0～5cm)土壤性质均具有相似的波状变化特征,其中>50μm砂粒含量与50～20μm微团聚体含量随坡长的增加呈降低趋势,而粘粒含量、比表面积(SSA)、20～2μm微团聚体含量、土壤有效磷(AP)与全磷(TP)含量以及土壤含水量均为增大趋势 ...
