摘要:
运用137Cs示踪法和网格点采样法对陕北典型的农耕地坡面的土壤侵蚀空间分布特征进行了研究，发现在坡脊和坡沟，随坡长的增长，137Cs含量分布呈增加、减少、再增加的波动趋势．而侧坡则呈相反的波动趋势；并利用新的公式计算了农耕地的侵蚀模数[11570t/（km2·a）]。
Abstract:
The soil erosion spatial variation feature of typical farmland slope was studied in North Shaanxi by 137Cs and grid sampling. the results indicatedthat the 137Cs amount appeared fluctuation strongly, weakly, and strongly again along incremental slope length on the slope back and gully, but the trend on the slope side appeared inversely; Also, the modulus of erosion in agricultural land was calculated by using a new model, being 11 570t/(km2·a).
