选用SLEMSA土壤侵蚀修正模型,在安徽省选择129个代表站点,分别计算了土壤流失比率、裸地土壤流失量、地形因子,得出安徽省土壤侵蚀量为7 683万t/a。分析发现,安徽省每年63.2%的土壤侵蚀分布在大别山区(占全省年土壤侵蚀总量的30.2%)和皖南山区(33%),提出这2个区域应作为安徽省水土保持综合防治工作的重点。
Select SLEMSA soil erosion correction model, selected 129 representative sites in Anhui Province, were calculated soil loss ratio, bare soil loss, topographical factors, resulting in soil erosion in Anhui Province was 76.33 million t / a. According to the analysis, 63.2% of the soil erosion in Anhui Province is distributed in the Dabie Mountains (accounting for 30.2% of the total annual soil erosion in the province) and the mountainous areas in Southern Anhui (33%). These two regions should be regarded as the comprehensive prevention and control of soil and water conservation in Anhui Province the key of.
