  1. 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 )植物籬笆生態系統年徑流量、年侵蝕量分別減少10 . 14 11 . 56倍和135 . 34 165 . 84倍;植物籬笆生態系統和大豆單作處理的徑流量、侵蝕量、可產生侵蝕的降雨量之間呈極顯著正相關,建立了相應的降雨產流、降雨產沙、徑流侵蝕模型,通過侵蝕雨量可以了解水土流失的發生特徵; 6月和8月份(多短時暴雨)水土保持能力較明顯。
  2. There was a highly significant correlation between the highest rain intensity in 30 minutes ( abbreviated as i30 ) and rv, and no significant correlation between rainfall capacity and 130. the soil conservation effects were better than the water conservation effects. the order of importance for water and soil conservation effects in different treatments was eragrostis curvula, kummerowia atriata, ixeris denticulata, with the most significantly positive correlation between each runoff and soil loss

    與裸坡相比,嚴重侵蝕地上植物籬笆的保土效果比保水效果更明顯,其中畫眉草( eragrostiscurvula )水土保持能力最強,雞眼草( kummerowiaatriata )次之,苦蕒菜( ixerisdenticulata )只具有保土作用;同時每次降雨產生徑流量與侵蝕量之間為極顯著相關關系。
  3. 2. on the basis of analyzing experimental data for slope land of loess plateau in different slope gradient and rain intensity and soil and water conservation tillage measures, using curve - fitting techniques, a soil infiltration rates model was woke out, the accuracy of the model is tested by a series of experiment data, the result of these indicate that the soil infiltration rates model is accurate and has good stability for slope land of loess plateau. 3. using soil infiltration rates and runoff time and wetting frontal surface depth of soil infiltration reflect effect of factor affecting soil infiltration rates

    ( 3 )採用土壤穩定入滲速率、坡面開始產流時間、土壤濕潤鋒面下滲深度三個指標來反映坡耕地土壤入滲影響(土壤性質、土壤初始含水率、地面坡度、降雨強度、積水深度、水土保持耕作措施等)因素效用大小,建立了各因素與三個指標的關系模型,詳細分析了不同水土保持耕作措施強化土壤入滲的影響,其中等高耕作作用最為顯著,其次是人工掏挖和人工鋤耕。
  4. The proportions of soil and water losses caused by heavy rain ( or storm ) were 65 % ~ 75 % and > 80 % respectively. there was extremely significant positive correlation between rainfall and runoff amount, while not - significant correlation between rainfall and soil loss was found

    降雨量與徑流量的均呈極顯著線性相關,降雨量越大,徑流量越大;而降雨量與土壤流失量的相關性明顯小於降雨量與徑流量的相關性,影響土壤流失量的因素比徑流量復雜。
  5. In the topic 2, based on the theory of rain - runoff and soil water moving, a practical soil moisture forecasting model expressed by moisture index has been provided. the techniques of moisture forecasting and drought evaluating have been combined with the techniques of network and gis, and the detailed way and contents about establishing information system of moisture and drought extent have also been presented, and provide direct services for preventing and controlling drought

    在墑情監測預報研究中,採用降雨產流預報和包氣帶水運移理論和方法,提出了由墑情預報指數表示的實用墑情預報模型,並把墑情預報技術、旱情災情評估技術與現代網路技術、 gis信息技術緊密結合,提出了建設墑情監測預報和抗旱減災信息系統的技術思路和具體內容。
