中文摘要 | 本文运用137Cs法,对陕北峁坡耕地的土壤侵蚀与泥沙运移进行了研究,定量地分析了峁坡侵蚀的特征,指出峁坡侵蚀存在由上往下呈强烈、减弱,再强烈、再减弱的波动。并利用非农耕地和农耕地土壤侵蚀公式,计算了峁顶非农耕地自1963年以来的侵蚀模数为1068t/(km2·a);农耕地的侵蚀模数为4059t/(km2·a)。并与径流试验场实测的梁峁坡坡耕地侵蚀模数进行了对比分析。 |
英文摘要 | 137Cs method was used to study soil erosion and sediment transportation in the farmlands on Mao (round loess mound) and slopes in North Shaanxi in this paper. A quantitative analysis was made of the erosion properties on Mao and slopes. The results indicated that erosion on Mao and slopes appeared to fluctuate very strongly, weakly, and very strongly again, and then weakly from the ups to the downs. Also, erosion equation for non-agricultural lands and agricultural lands has been used to calculate the modulus of erosion in non-agricultural lands on the Mao top since 1963, being 1 068 t/(km2·a), while the modulus of erosion in agricultural lands is 4059 t/(km2·a), Also, a comparative analysis was made of actual determined modulus of erosion of sloping farmlands in the runoff experimental fields on Liang (elongated loess mound) , Mao and slopes. |
