山东省土壤侵蚀敏感性评价及其空间分布特征
Evaluation on Soil Erosion Sensitivity and Its Spatial Distribution Characteristics in Shandong Province
摘要
Abstract
Soil erosion usually results from the comprehensive effects of geology, geomorphology, climate, soil, vegetation and human activity. Based on the Universal Soil Loss Equation, this paper classified and evaluated impact factors of soil erosion sensitivity in Shandong Province, with the index of rainfall erosivity, topographic relief, soil erodibility and vegetation coverage. Also, we pointed out the possible degree of occurring soil erosion and its spatial distribution characteristics. Results were as follows. The soil erosion sensitivity of Shandong Province was mainly mild and moderate. The two together areas were 8.48×104 km2, accounting for 53.69%of Shandong Province's land area. There were obvious differences in spatial distribution. The degree of soil erosion sensitivity was highest in hilly and mountainous area of central south of Shandong Province, which was followed by the Jiaodong hilly region, and it was weakest in southwest and northwest yellow flood plains of Shandong Province.关键词
