  • erosion modulus
  • modulus of erosion

例句與用法

  • The results show that the annual mean erosion rate ( ca . 45 years ) is 15850 t / km2 - yr and its spatial distribution has clear difference
    研究表明,坡耕地年平均侵蝕模數為15850叭燦2 . a ) ,具有明顯的空間分異格局。
  • There was no direct correlation between runoff module and erosion module , but there was an obvious consistency between runoff module variation and erosion module variation . the catchments with large runoff module variation also had a large erosion module variation . 5
    徑流模數和侵蝕模數多年平均值之間沒有直接的相關性,而徑流模數的變化和侵蝕模數的變化之間有很好的協同性,徑流模數變異大的集水區對應的侵蝕模數變異也大。
  • The land use spatial distribution pattern had a decisive impact on the inter - year variation characteristics of both runoff and sediment . the catchments , which had even land use spatial distribution , had small inter - year variation of both runoff and sediment , and vice versa . 6
    集水區內土地利用類型空間分布均勻,則該集水區對應的徑流模數和侵蝕模數年際變化小;反之,土地利用類型空間分布格局不均勻的集水區,徑流和泥沙的年際變化則大。
  • Fourthly , critical value of erosive modulus , which may cause soil carbon and nutrient changing , has been taken . the results of simulation showed that different soil nutrient element ( c , n , p , k ) have different soil acceptable erosive modulus in different land use types . for example , in this study , the critical value for nitrogen is located in the range of 1500 - 2000t / km2for forest land , 2000 - 2500 t / km2 for tillage land , 2500 - 3000 t / km2 for garden land , and 1000 - 1500 t / km2
    四、得到了引起土壤碳和養分發生變化的侵性模數閥值:通過對地塊土壤侵蝕模數、碳和養分含量變化的計算,得到了不同利用類型中不同元素含量出現下降的最低侵蝕模數閥值,如耕地全氮為2000一2500噸,果園全氮為3000一3500噸,林地全氮為1000一1500噸,草地全氮為1000 - 1500噸,從而為流域侵蝕治理規劃和生態環境建設提供了科學依據。
  • The results show that topographic slope gradient has important influence on soil and water loss , the bigger slope gradient and the more soil and water loss , and the slope gradient 15 is a relative threshold of soil erosion modulus , but the influences of topographic height and slope aspect are slight
    結果表明:地形坡度是影響徑流和泥沙產生的重要因素,產生徑流和泥沙的模擬值隨地形坡度的增大而增大,地形坡度15是坡耕地土壤侵蝕模數的相對質變點;地形高程和坡向對產生徑流和泥沙的影響不大。
  • The paper establishes a mathematical model for calculating soil erosion modulus and a method for calculating new soil loss by using annual rainfall data and individual rainfall data , taking the outcomes of tests and study of natural rainfall , artificial rainfall and washout as a basis , rainfall erosion force , soil resistance to erosion and ground slope as main factors and combining with the study on new soil loss in typical regional development and construction
    摘要以天然降雨、人工降雨、放水沖刷等試驗研究成果為基礎,結合典型區域開發建設新增土壤流失分析的研究成果,以降雨侵蝕力、土壤抗沖性和地面坡度為主要因子,建立了用年降雨資料和次降雨資料計算土壤侵蝕模數的數學模型和開發建設新增土壤流失量的計算方法。
