摘要
在理论分析、试验观测、外业调查的基础上,从黄土成土速度、坡耕地表土养分平衡、保持坡耕地土地生产力基本稳定、黄河河道的容许来沙量、当地经济的不断发展及土壤培肥和施肥能力的巨大潜力等角度综合分析,确定2.00t/(hm^2·a)作为半干旱黄土丘陵区坡耕地的土壤容许流失量,在较长时期内是比较合理的。
Based on theoretical analysis, field examination and investigation, it is considered that the 2. 0t/ (hm2 . a) is the rational soil loss tolerance of sloping field in semi-arid hill-gully area of the Loess Plateau during the long period according to soil formation velocity, top soil nutrient balance, land productivity stability in sloping field, sediment transport tolerance of the Huanghe River course, and regional economic development and so on.
