一、土壤流失预报日本湿润地区的土壤侵蚀,主要是水力侵蚀,在制订土壤保持规划时,需要对降雨引起的耕地土壤流失量进行预报。为此作者利用了美国农业部农业研究机构提出的土壤流失通用公式:A=RKSLCP并研究了该公式中的各项因素,使之适用于计算日本的土壤侵蚀。
Soil Loss Prediction Soil erosion in humid areas of Japan is dominated by hydraulic erosion. Soil erosion planning needs to be predicated on the amount of soil loss caused by rainfall. For this reason, the authors used the general formula for soil erosion proposed by the USDA Agricultural Research Institute: A = RKSLCP and studied the factors in the formula to make it suitable for calculating soil erosion in Japan.
