In this paper, the spatial distribution of soil erosion intensity on a long and straight cultivated slope was studied using 137Cs measurement and wavelet analysis. The results showed that there existed an fluctuant period of soil erosion intensity with 142m along 4 transects downslope, which suggested that the intensity of soil transporting changes between weak and strong alternately downslope during the impact of long-term erosive rainfall.

本研究通过采集开垦近100年的黑土直型坡耕地的土壤样品，利用137Cs示踪技术，结合小波分析方法，研究了长坡长直型坡耕地50多年来土壤侵蚀强度的空间变化规律，结果显示4个断面顺坡方向上的坡面侵蚀强度均存在着坡长为142 m的强弱交替变化的波动周期，这反映了长坡长直型坡土壤在长期的降雨侵蚀过程中，泥沙沿坡面输移的强弱交替变化。
