annual soil loss 中文意思是什麼
annual soil loss
解釋
年土壤流失量-
Runoff amount in rainy season for different land - use types constituted more than 50 % of annual amount, while the proportion in drought season was less than 17 %. of annual total soil loss amount, the control accounted for 60 % and complex proportions for other lands. however, soil loss amounts in drought season for all lands were lowest in one year
雨季徑流量均佔全年的50以上,而旱季徑流量佔全年的17以下;而不同土地利用方式的土壤流失量佔全年流失量的比例則較為復雜,對照土壤流失量佔全年的60 ,而其它土地利用方式由於植被覆蓋、耕作和管理措施的季節性可能發生3 6月的土壤流失量小於7 10月的流失量,但旱季土壤流失量所佔比例均最小。 -
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。
