soil erosion modulus meaning in English

土壤侵蚀指数

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
结果表明：地形坡度是影响径流和泥沙产生的重要因素，产生径流和泥沙的模拟值随地形坡度的增大而增大，地形坡度15是坡耕地土壤侵蚀模数的相对质变点；地形高程和坡向对产生径流和泥沙的影响不大。
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、放水冲刷等试验研究成果为基础，结合典型区域开发建设新增土壤流失分析的研究成果，以降雨侵蚀力、土壤抗冲性和地面坡度为主要因子，建立了用年降雨资料和次降雨资料计算土壤侵蚀模数的数学模型和开发建设新增土壤流失量的计算方法。
