In spring 2005, daily particulate matter (PM 2.5 ) aerosol samples were collected at Tongliao, a site in the Horqin sand land of northeastern China. The concentrations 20 elements, 9 water‐soluble ions, and elemental organic carbon (EC OC, respectively) determined filter samples. Crustal material was major contributor to PM mass, but rural biomass burning local urban pollution also influenced composition aerosol. mean mass concentration 126 ± 71 μ g m −3 (arithmetic standard deviation), with...
To provide a basis for tracing changes in vegetation and tree cover density, we studied the phytoliths of 129 common temperate plant species, extracted from 75 surface soil samples sites grassland, forest−grassland ecotone forest habitats northeast China. From analysis shapes morphological parameters samples, developed reference data set herbaceous woody phytoliths, subsequently identified 21 13 phytolith types samples. test reliability distinguishing forest, grassland ecotone, used...
Phytoliths are a reliable paleovegetation proxy and have made an important contribution to paleoclimatic studies. However, little is known about the depositional processes affecting soil phytoliths, which limits their use for paleoclimate reconstructions. Here, we present results of study vertical translocation characteristics phytoliths in 40 natural profiles Northeast China. The show that phytolith concentration decreases within humic horizon ∼22% translocated below surface studied soils....
High-resolution proxy-based paleoenvironmental records derived from peatlands provide important insights into climate changes over centennial to millennial timescales. In this study, we present a composite climatic index (CCI) for the Hani peatland northeastern China, based on an innovative combination of pollen-spore, phytolith, and grain size data. We use CCI reconstruct variations East Asian summer monsoon (EASM) intensity during Holocene. This is accomplished with complete ensemble...
The Songnen grasslands were traditionally thought to be dominated by Artemisia and Chenopodiaceae plants as early the late Pleistocene. However, increasing evidence has called that interpretation into question. To shed new light on paleovegetation evolution of arid semi-arid steppe in North China, phytolith assemblages preserved region’s sand-paleosol sequence (section Daike) are used a proxy for structure. Results show both sand paleosol layers grassland sections contain well-preserved...
