pollen tracing孢粉示踪
1.Therefore, can pollens be used as tracers for soil erosion and sedimentation studies? Surface soils, modern and ancient reservoir deposits were sampled as a test of the pollen tracing technique for studies of vegetation changes, erosion, and sedimentation in the Zhouwan Reservoir Catchment of the Loess Plateau, Wuqi County, North Shaanxi, China.如同137Cs和210Pbex核尘埃,土壤和坝库沉积物中的孢粉也源于大气沉降,是否能用于侵蚀产沙的示踪研究?在陕北吴旗周湾水库采集了一些表层土壤和现代淤地坝、古代聚湫坝沉积泥沙的样品,尝试土地利用/覆被变化和侵蚀产沙的孢粉示踪研究。
