modulus of soil erosion 解釋
土壤侵蝕模數
  • modulus : n. （pl. -li ） 【數、物】模數，模量；系數。 a modulus of elasticity 彈性模量。
  • of : OF ＝Old French 古法語。
  • soil : n 1 泥土，土壤；土質。2 土地，國土。3 滋生地，溫床。4 農業生活，務農。n 1 臟東西，污物，污穢，污...
  • erosion : n. 1. 腐蝕，侵蝕（作用）。2. 【醫學】糜爛，齒質腐損。
  1. 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。
  2. 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。
