slight erosion 中文意思是什麼
slight erosion
解釋
輕度糜爛-
Experiments of artificial rainfall showed that sediment is the main body of total nutrient loss and runoff is the main body of available nutrient loss when erosion is slight, but sediment become the main body of total and available nutrient synchronously while erosion is intense. concentration of nutrient in runoff is most likely to be affected by concentration in topsoil. the higher concentration in topsoil is, the more possible nutrient loss by runoff is
人工降雨實驗結果表明，在降雨強度和侵蝕強度不大時，侵蝕泥沙是全量養分流失的主體，地表徑流則是速效養分流失的主體；而當在降雨強度和侵蝕強度極為劇烈時，侵蝕泥沙成為全量養分和速效養分二者流失的主要載體；地表徑流中的養分含量很大程度上受土壤中養分含量的影響，土壤中養分含量越高，養分徑流流失的可能性越大。 -
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。
