Proxy-based reconstructions and modeling of Holocene spatiotemporal precipitation patterns for China Mongolia have hitherto yielded contradictory results indicating that the basic mechanisms behind East Asian Summer Monsoon its interaction with westerly jet stream remain poorly understood. We present quantitative derived from 101 fossil pollen records analyse them help a minimal empirical model. show jet-stream axis shifted gradually southward became less tilted since middle Holocene. This...
Understanding the history and regional singularities of human impact on vegetation is key to developing strategies for sustainable ecosystem management. In this study, fossil modern pollen datasets from China are employed investigate temporal changes in composition, analogue quality, diversity during Holocene. Anthropogenic disturbance vegetation's responses also assessed. Results reveal that assemblages non-forest communities fail provide evidence western part (annual precipitation less...
Abstract Vegetation around the Daihai Lake, northern China, is very sensitive to climate changes. In this paper, pollen-based quantitative reconstructions using three methods [weighted averaging partial least squares method (WAPLS), modern analog technique (MAT), and pollen response surface (PRS)] were conducted obtain robust of Holocene changes in Lake area. The result obtained by all consistently show annual precipitation have been 50–100 mm lower early Holocene, 100–200 higher...
Abstract. We collected the available relative pollen productivity estimates (PPEs) for 27 major taxa from Eurasia and applied them to estimate plant abundances during last 40 ka cal BP (calibrated thousand years before present) using counts 203 fossil records in northern Asia (north of 40∘ N). These were organized into 42 site groups regional mean calculated REVEALS (Regional Estimates Vegetation Abundance Large Sites) model. Time-series clustering, constrained hierarchical detrended...
Abstract. A modern pollen dataset with an even distribution of sites is essential for pollen-based past vegetation and climate estimations. As there were geographical gaps in previous datasets covering the central eastern Tibetan Plateau, lake surface sediment samples (n=117) collected from alpine meadow region on Plateau between elevations 3720 5170 m a.s.l. Pollen identification counting based standard approaches, data interpolated a robust meteorological dataset. series numerical analyses...
Abstract Aim Fossil pollen spectra from lake sediments in central and western Mongolia have been used to interpret past climatic variations, but hitherto no suitable modern pollen–climate calibration set has available infer climate changes quantitatively. We established such a dataset it develop transfer function model that we applied fossil record order investigate: (1) whether there was significant moisture response the Younger Dryas event north‐western Mongolia; (2) early Holocene...
Abstract. Pollen records from Siberia are mostly absent in global or Northern Hemisphere synthesis works. Here we present a taxonomically harmonized and temporally standardized pollen dataset that was synthesized using 173 palynological adjacent areas (northeastern Asia, 42–75∘ N, 50–180∘ E). data were harmonized, i.e. the original 437 taxa assigned to 106 combined taxa. Age–depth models for all revised by applying constant Bayesian age–depth modelling routine. The is available as count...
This study examines the course and driving forces of recent vegetation change in Mongolian steppe. A sediment core covering last 55 years from a small closed-basin lake central Mongolia was analyzed for its multi-proxy record at annual resolution. Pollen analysis shows that highest abundances planted Poaceae diversity occurred during 1977–1992, reflecting agricultural development area. decrease an increase Artemisia abundance after 1992 indicate enhanced degradation times, most probably...
