朝阳县土壤侵蚀特征研究

Study on Soil Erosion Characteristics in Chaoyang County

研究分析了USLE方程中的各因子计算方法,并计算分析2021年朝阳县土壤侵蚀受坡度和土地利用类型影响后具备的特征。结果表明:2021年朝阳县水土流失面积1481.39km^(2),其中轻度、中度、强烈、极强烈及剧烈侵蚀面积分别为1108.92km^(2)、206.87km^(2)、77.46km^(2)、70.17km^(2)和17.97km^(2),中度及以下侵蚀面积占比88.82%,平均侵蚀模数1285.42t/(km^(2)·a)。结合具体情况提出相应的预防保护管理与控制措施。

This study analyzes the calculation methods of each factor in the USLE equation,and calculates and analyzes the characteristics of soil erosion affected by slope and land use type in Chaoyang County in 2021.The results showed that the soil erosion area of Chaoyang County in 2021 was 1481.38km^(2),of which the mild,moderate,strong,extremely strong and severe erosion areas were 1108.92km^(2),206.87km^(2),77.46km^(2),70.17km^(2) and 17.97km^(2),the moderate erosion area accounted for 88.82%,and the average erosion modulus was 1285.42t/(km^(2)·a),and corresponding preventive protection management and control measures were proposed according to the specific conditions.
