东北典型厚层黑土区坡耕地侵蚀对土壤质量的影响

open access: yesShuitu Baochi Xuebao
目的阐明东北黑土区土壤侵蚀-沉积对坡耕地土壤质量的影响,可为黑土资源保护和可持续利用提供重要科学依据。方法选取黑龙江省克山县的2块厚层黑土区的坡耕地,采用137Cs示踪技术估算土壤侵蚀速率,基于最小数据集方法构建土壤质量评价指标,分析典型厚层黑土区土壤侵蚀-沉积对坡耕地土壤质量的影响。结果1)研究区坡耕地土壤侵蚀-沉积速率为-1 563.2~7 916.1 t/(km2·a),平均侵蚀速率为2 669.0 t/(km2·a)。且土壤侵蚀速率在坡面空间分布上均表现为坡中下部侵蚀强烈,坡顶和坡中上部为轻度 ...
