摘要
应用13 7Cs示踪法对陕西延安燕沟流域自然坡面上坡度与侵蚀强度之间的关系进行了研究。结果表明 ,坡面各点的坡度与侵蚀强度之间呈幂或指数函数关系 ,且相关性极显著 ,即随着坡度的增加 ,侵蚀强度呈幂或指数函数增加 ;偏相关分析结果表明 ,侵蚀强度与坡面平均坡度之间呈正相关关系 ,其相关系数为 0 4447。
By using 137 Cs as tracer, the relationships between slope gradient and soil erosion intensity were studied on the natural slopes in Yangou gully,Yan′an,Shaanxi Province. The results shows that the power functions or exponential functions exist between the gradients and erosion intensities on the slope points, and this kind of relativity is very notable. Positive partial correlation exists between average gradients and soil erosion intensities, the coefficient is 0 4447
