本文根據598084號年浙江省自然科學基金項目和g59901號國家教育部回國留學人員科研啟動基金項目的部分研究目標和研究內容的要求應用概率分析方法研究了在隨機風浪荷載作用下和築堤材料隨機性影響下防護堤壩抗滲流、抗沖刷穩定性的分析計算模型；用數值分析方法研究了在浪潮能量作用下岸灘侵蝕造成海岸演變問題的數學分析模型。( 1 ) in newly - constructed stage and early stage of reclamation, the most important factor of runoff is 30min rainfall intensity. in later stage of reclamation, the most important one is 45min rainfall intensity. and the runoff capacity is the most important influence factor to soil erosion always ; ( 2 ) on the certain degree, loosening surface has an active function to infiltration condition but not to conserve soil ; ( 3 ) the most runoff is formed on platform of stackpile and the soil erosion often happens in the slope ; ( 4 ) stone - soiled dumps have an advantage over soil at respect of erosion resistance so that soil is not adapt in covering slope ; ( 5 ) grass has a better role in conservation of water and soil than arbor in early stage of reclamation ; ( 6 ) arbor - arboret - hemp mix is the best model for conservation
結果顯示：在未復墾時期和復墾初期， 30min降雨強度對徑流影響最大，復墾後期徑流與45min雨強相關性最強，而徑流量對土壤侵蝕量的影響始終最大；通過疏鬆地表巖土只在一定程度上改善地表的入滲條件，並不能起到保土的作用；平臺為徑流的主要形成區，而土壤侵蝕主要集中在斜坡；土石混排坡的土壤抗蝕性比覆土坡的要大得多，在排土場形成過程中不宜用厚層黃土覆坡；在復墾初期，純草模式水土保持效果明顯好於純喬模式。In this dissertation, rainfall infiltration, runoff, and soil water redistribution on a hillslope were studied by simulated rainfall experiments, and soil water cycling was investigated by site observation and soil sampling methods. moreover, the reasons for the desiccation of deep soil layer were analyzed, and its assessment indexes and standards were presented. the main results are as follows : ( 1 ) rainfall infiltration into a planar hillslope with a homogeneous isotropic soil could be simply regarded as one - dimensional infiltration process, if soil erosion was prevented
針對當前該區植被恢復重建中存在的科學問題，以植被建設的關鍵性限制因素?土壤水分為出發點，通過室內外模擬降雨試驗，研究了坡地降雨入滲、產流及土壤水分再分佈規律，同時採用定位觀測和采樣分析相結合的方法，分析了坡地土壤水分的循環與轉化特徵，並初步建立了深層土壤乾燥化程度的評價標準，取得的主要結論如下： （ 1 ）在防止土壤侵蝕的條件下，均質坡地的降雨入滲過程可以簡化為一維。By means of prototype observation, analysis with materials and theories, and laboratory test, the author deeply analyzed the causes and procedure of canal cross section erosion, and obtained eight causes which resulted the canal deform including flow, seepage, runoff, collapse of bank, dry effect, human activity, wave flush, frozen, and then stressed to discuss the frozen process
本文通過原型觀測、資料分析、理論分析、室內試驗對北引渠道變形的成因和發生機理進行了較為深入的分析研究，給出了造成北引渠道變形的八大原因：流水引起的變形、滲透引起的沖刷、地表徑流引起的沖刷、滑坡變形、乾燥作用、人類和動物活動的影響、風浪引起的沖刷、凍融侵蝕，並著重闡述了凍融侵蝕的機理。From the changes in soil erosion upon the slope, the dynamic processes of runoff and soil erosion along slope was analyzed. with ree to trace the processes of soil erosion
結皮對土壤侵蝕的影響主要反映在徑流造成的土壤侵蝕中，給出了結皮效應率的定義，並據此定量評價了結皮對土壤入滲、土壤侵蝕的影響。Soil crust, a common phenomenon for many soils worldwide, plays an important role in water and soil losses. soil seals and crusts can significantly reduce soil infiltration rate and subsequently lower the utilization of water resources, increase runoff, and induce heavier soil erosion
造成水土流失一個極其重要的原因是降雨引起的土壤表面結皮，降低了土壤的入滲性能，增加丁土壤表面的徑流，加大了土壤侵蝕。The objectives of this study were : i ) to understand the mechanism of applying polyacrylamide ( pam ) to control crust formation, to increase infiltration and reduce soil erosion ; and ii ) to quantify the dynamics of soil erosion processes with rare earth elements ( ree ) tracers
