通过137Cs示踪和土壤粒度分析,着重探讨了河北坝上地区土地利用与土壤风蚀的关系,揭示了不同土地利用类型的侵蚀强度为沙质丘陵草原>耕地>退耕还草地>人工林>石质丘陵草原,提出了对研究区保持石质丘陵草原现状、保护原有人工林等植被恢复的建议。
Through 137Cs tracing and soil particle size analysis, the relationship between land use and soil wind erosion in Bashang area of Hebei Province was discussed emphatically. It was revealed that the erosion intensity of different land use types was sandy hilly grassland> arable land> returning farmland to grassland> artificial forest> stony Hilly grassland, put forward the suggestion to maintain the status quo of stony hilly grassland in the study area and protect the original plantation and other vegetation restoration.
