erosion modulus
解釋
侵蝕模數-
Using emended gauss diffusion mode, taking wind erosion modulus as the ground oil pollutant sources, dust and oil pollutant quantity in air and polluting load in water were calculated, a relative model was founded
本文以土壤侵蝕的風洞實驗求得污染源源強，採用高斯模式對地表風蝕作用的傳輸量進行估算，進而對石油開發區落油通過大氣傳輸途徑對區域水環境（博斯騰湖）的影響進行了預測，建立了相應的模型。 -
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。 -
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。 -
