侵蚀模数 meaning in English
erosion modulus
modulus of erosion
Examples
- 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，坡耕地年平均侵蚀模数为15850叭灿2 . a ) ，具有明显的空间分异格局。 - 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
径流模数和侵蚀模数多年平均值之间没有直接的相关性，而径流模数的变化和侵蚀模数的变化之间有很好的协同性，径流模数变异大的集水区对应的侵蚀模数变异也大。 - 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
集水区内土地利用类型空间分布均匀，则该集水区对应的径流模数和侵蚀模数年际变化小；反之，土地利用类型空间分布格局不均匀的集水区，径流和泥沙的年际变化则大。 - 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养分发生变化的侵性模数阀值:通过对地块土壤侵蚀模数、碳和养分含量变化的计算，得到了不同利用类型中不同元素含量出现下降的最低侵蚀模数阀值，如耕地全氮为2000一2500吨，果园全氮为3000一3500吨，林地全氮为1000一1500吨，草地全氮为1000 - 1500吨，从而为流域侵蚀治理规划和生态环境建设提供了科学依据。 - 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。
