  • Ii ) runoff erosivity reflects relationship of water erosion forces and sediment yield more directly than rainfall erosivity . it intergrated ability of runoff volume and flood peak on detaching soil and transporting sediment and is more reasonable than single runoff depth or flood peak volume
    ( 2 )以径流侵蚀力代替降雨侵蚀力来反映水蚀营力与产沙量的关系更加直接,而且综合了径流量与洪峰在剥蚀土壤和搬运泥沙能力,比单独运用径流深或洪峰流量更加合理。
  • In order to eliminate the hidden trouble caused by storm runoff erosion , the mechanism of the storm runoff erosion on the slope surface of the yellow river dykes has been studied in this thesis . through the simulation rainfall experiments and field observations , the formation mechanism of storm runoff scouring , rills and sockets have been opened up . meanwhile the possible control measures have been suggested
    为了防治黄河大堤由于暴雨径流冲刷造成的不安全隐患,本文针对黄河大堤上的暴雨径流侵蚀进行了实地设站观测及室内模拟降雨侵蚀试验,通过揭示大堤暴雨冲刷过程机理,查清水沟、水穴(浪窝)等的成因,提出相应的防治对策。
  • Moreover , hedgerow ecosystems were effective in controlling water and soil loss in june and august . under simulated rainfall , hemercoallis citrina baroni and p . rotation flligg hedgerow ecosystems had a significant effect on reducing water and soil loss in their later stages of plant growth , and there was a significant positive correlation between the effect on reducing water and soil loss and the rain intensities . moreover , hedgerow ecosystems decreased more soil loss than runoff , and the initial time of runoff incidences could well represent the water and soil conservation effects of hedgerow ecosystems
    Rotatumflligg )植物篱笆生态系统年径流量、年侵蚀量分别减少10 . 14 11 . 56倍和135 . 34 165 . 84倍;植物篱笆生态系统和大豆单作处理的径流量、侵蚀量、可产生侵蚀的降雨量之间呈极显著正相关,建立了相应的降雨产流、降雨产沙、径流侵蚀模型,通过侵蚀雨量可以了解水土流失的发生特征; 6月和8月份(多短时暴雨)水土保持能力较明显。
  • Relationship model among topography fractal dimension , runoff eroding power and sediment transport modulus was established after proposing topography fractal dimension as comprehensive quantitative index for topography by replacing rainfall erosivity with runoff erosivity . based on this model , relationship between watershed topography parameter and sediment yield were setup using the observed data from cha bagou watershed , together with parameter calibration
    提出了以地形分维数作为地貌形态综合量化的指标,以径流侵蚀力代替降雨侵蚀力的思想,建立了模型流域地形分维数、径流侵蚀力与输沙模数之间的关系模型;在此基础上,应用岔巴沟流域实测资料,建立了流域地貌形态参数与侵蚀产沙关系模型,并进行参数率定和检验。
