利用CSLE模型计算并分析了在无水土保持工程和耕作措施条件下黄河中游河龙区间土壤侵蚀各因子特征值以及2011年的潜在土壤侵蚀情况.结果表明:降雨侵蚀力因子和坡度坡长因子的分布与潜在土壤侵蚀的分布呈一定的相反趋势,土壤可蚀性因子和植被覆盖与生物措施因子则表现出一致性.2011年潜在土壤侵蚀模数为2 600.1 t/(hm2·a),潜在土壤侵蚀面积占整个区间总面积的50.45%,并且以强烈侵蚀为主,造成的水土流失较为严重.
Based on the CSLE model, the eigenvalue of soil erosion factors and the potential soil erosion in the middle reaches of the Yellow River under the condition of soilless soil conservation and tillage were calculated and analyzed. The results showed that the factors of rainfall erosivity and longitude slope Distribution of soil erosion and potential distribution of soil erosion showed a certain opposite trend, and soil erodibility factor and vegetation cover and biological measures were consistent. The potential soil erosion modulus in 2011 was 2 600.1 t / (hm2 · a) The area of soil erosion accounts for 50.45% of the total area of the whole section, and is dominated by intense erosion, resulting in serious soil erosion.
