通过11年的坡耕地径流小区试验,获得了较为系统的坡耕地土壤流失资料,经分析整理确定了影响坡耕地土壤流失之因子参数,以这些参数为基础建立了辽北地区坡耕地土壤流失方式E=12.66RKLSCP,经实际检验,此方程式的标准差为59.Ot/(km~2·a),相对误差极值为63%。
Through 11 years of experiment on slope farmland runoff plots, the soil erosion data of sloping farmland was systematically obtained. Factors affecting the soil loss on sloping farmland were determined and analyzed. Based on these parameters, the soil loss patterns of sloping farmland in northern Liaoning were established E = 12.66RKLSCP, the actual test, the standard deviation of this equation is 59. Ot / (km ~ 2 · a), the relative error of the extreme is 63%.
