  1. And the major results and some new viewpoints were presented as follow : 1 ) sediment content of cn tillage system in runoff process is substantially low compared to st under rainfall with high intensity, showing cn bear the efficient capacity of control soil loss. nevertheless, when soil is saturated, the runoff intensity of both tillage systems is near, implicating cn has the limited function of reducing runoff. 2 ) based on the case analysis of observed all rainfall - runoff generation processes, a ) the initiation time hysteresis of surface runoff generation is notable when rainfall fall upon the unsaturated purple soils, which is attributed to the property of rapid water sorption and much non - capillary porosity

    經近幾年的觀測和理論分析,取得了以下結果和創新的認識: 1 )在降雨強度較大的情況下,保護性耕作制? ?聚土免耕的產沙強度明顯較常規耕作制? ?順坡耕作的小,說明聚土免耕耕作制防治土壤流失是有效的;但當土壤達到飽和后,聚土免耕的徑流強度與常規耕作的差異較小,產沙強度也增大,因此,聚土免耕防治水土流失的能力是有限的。
  2. When soil antecedent condition is dry and the initial rainfall intensity is high, peak surface runoff also considerably lag behind that of rainfall, because of the formation of temporary relative impermeable top layer ; b ) surface runoff is controlled primarily by infiltration - excess runoff mechanism under unsaturated condition ; the major fraction of surface runoff are dominated by saturated infiltration - excess runoff response, only a small fraction by return flow mechanism when soil is saturated ; c ) subsurface flow is dominated by saturated runoff mechanism, and the duration of subsurface post the rainfall end is dependent upon rather the soil properties than the rainfall characteristics ; d ) subsurface flow intensity in cultivated soil layer ( 0 ~ 20cm ) is high up to 35mm / h when rainfall intensity is up to 120mm / h, indicating the existing of macropores and pipe flow in cultivated layer

    2 )耕作制下紫色土的產流主要機制是: 1 )當雨前土壤含水量未達到飽和狀態時,表面產流起始時間有明顯滯后現象,這與紫色土的快吸水性和較多非毛管孔隙密切相關;當雨前土壤較乾燥,降雨初期雨強較大時,易形成臨時相對不透水表層,表面產流峰也有明顯滯后現象。 2 )表面徑流的產流方式主要是超滲產流,當土壤達到飽和狀態后,有四川大學博士學位論文小部分回歸流發生,但主要是飽和超滲產流發生,因為紫色土的相對不透水層和其它透水障礙層不明顯。 3 )壤中流主要是飽和產流,與降雨過程有明顯的滯后,而且雨停后的壤中流產流歷時與降雨特徵無關。
  3. Three - dimensional high - density space / time soundings serve as the main body of data consisting of 3 - hr interval doppler probings, 10 - 30 min rainfall intensity, surface raindrop sizes sampling and gps - guided flight cloud physics detections with output taken at 2 - sec and 200 - m intervals. and specific systems associated therewith are developed for multiple - way communication and data collection and storage, a platform for analysis, retrieval softwares for dominant items and multi - scale cloud models - all constitute a system of techniques for meso to microscale observations and analysis. 2 ) atmospheric water resource and macroscopic rainfall properties in dry periods of spring and autumn of the target region

  4. The results show that selection of radiation parameterization schemes has distinct impact on the simulated results. the results simulated by the group with detailed long - wave and short - wave radiation parameterization scheme reflect plateau terrain and typhoon, cloud, subtropical high, trough / ridge more particularly and reasonably ; intensity of typhoon rainfall center is improved 1 / 3, there have been some improvements on intensity of the north heavy snow, more approach the observation

    通過對2002年第16號臺風個例和2002年12月19 24日降雪個例的模擬,結果表明:選用不同的輻射參數化方案對模擬結果具有明顯的影響,較詳細的長短波輻射參數化方案組合模擬的各種輻射量和雲對地形以及臺風、副高和槽脊等天氣形勢的反映更加細致合理;降水的預報也更加接近實況。
  5. The experiment indicated that the lower rainfall intensity treatment, lasting longer time, caused more losses amounts of runoff nitrogen than that under the high rainfall intensity with same total rainfall amount

    試驗還表明,在降雨量相同的條件下,降雨持續時間長的小雨引起的農田氮素徑流流失量要超過降雨持續時間短的大雨。
  6. Soil erosion was extremely serious by high intensity storm with high rainfall energy

    這種高強度暴雨所具有的特高降雨能量造成的土壤侵蝕是極嚴重的。
  7. The instantaneous unit hydrograph theory would be suitable for the high antecedent baseflow and the high rainfall intensity to estimate the direct runoff, but it still needs to prove its fitness with much more cases

    在臨前基流量較大或降雨強度較大時,應用瞬時單位歷線理論分析逕流特性之準確性較高,然確實之適用條件仍有待進一步之研究。
  8. Because of the existence of meiyu precipitating cloud band the temperature dv is faint inside the meiyu trough and on account of large - scale prominent terrain available, significant temperature dv occurs on both sides of the trough, leading to the reinforcement of the subtropical high and middle latitude transformed high, and the deepening and narrowing of the trough in the night with the result that the relative intensity and precipitating function of the meiyu frontal rainfall system are changed at day and night, resulting in precipitation dv

    由於梅雨雲帶的存在,梅雨鋒低壓槽內溫度日變化很微弱;由於梅雨系統四圍高大地形的存在,梅雨鋒低壓槽南北兩側溫度日變化非常明顯,使南海副高和中緯度變性高壓在夜間增強,梅雨鋒低壓槽也在夜間變深、變窄,改變了早、晚時刻梅雨系統的相對強度和降水功能,導致降水日變化。
  9. The soil co2 dynamics response to rainfall in the soil section was regular migration process : one gradient with up - high and down - low before rainfall - two gradient with up and down high and middle - low from the beginning rain - one gradient with up - high and down - low. the intensity of rainfall will influence the co2 concentration in the soil

    濃度動態對降雨的響應表現為一個完整的有規律的動力遷移過程:降雨前上低下高單向梯度一降雨過程中及降雨後一段時間內上高下高中低的雙向梯度一恢復上低下高的單向梯度。強度不大的降雨可能會促進土壤co 。
