摘　　要：土壤侵蚀是地质、地貌、气候、土壤、植被以及人类活动综合作用的结果。本文以通用土壤流失方程为基础,选取了降雨侵蚀力、地形起伏度、土壤可蚀性及植被覆盖等因子作为土壤侵蚀敏感性的评价指标,对山东省土壤侵蚀敏感性的影响因子进行了分级和综合评价,明确了山东省土壤侵蚀发生的可能程度及空间分布特征。结果表明:山东省土壤侵蚀敏感性以轻度和中度为主,轻度敏感区和中度敏感区面积8.48×10~4 km^2,占全省陆域面积的53.69%。空间分布差异明显,鲁中南山地丘陵区土壤侵蚀敏感性程度最高,其次为胶东丘陵区,鲁西南与鲁西北黄泛平原区土壤侵蚀敏感性较弱。Soil erosion usually results from the comprehensive effects of geology,geomorphology,climate,soil,vegetationand human activity.Based on the Universal Soil Loss Equation,this paper classified and evaluated impact factors of soilerosion sensitivity in Shandong Province,with the index of rainfall erosivity,topographic relief,soil erodibility andvegetation coverage.Also,we pointed out the possible degree of occurring soil erosion and its spatial distributioncharacteristics.Results were as follows.The soil erosion sensitivity of Shandong Province was mainly mild and moderate.The two together areas were8.48×104km2,accounting for53.69%of Shandong Province’s land area.There were obviousdifferences in spatial distribution.The degree of soil erosion sensitivity was highest in hilly and mountainous area of centralsouth of Shandong Province,which was followed by the Jiaodong hilly region,and it was weakest in southwest andnorthwest yellow flood plains of Shandong Province.
