河北坝上地区不同土地利用类型的土壤风蚀研究

Soil Wind Erosion under Different Land Use Types in Bashang of Hebei Province

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。

By the trace of ^137Cs and soil granularity analysis,the relationship between land-use and soil wind erosion was investigated in Bashang of Hebei Province.The results indicate that the land use types with erosion intensity,from the higher to the lower,are sandy hilly grassland 〉cultivated land 〉grassland converted from cultivated land artificial forest gravel hill grassland.Hence,to recover the vegetation,the gravel hilly grassland in this region should be reserved and the original vegetation in it should be protected.
