European pollen-based REVEALS land-cover reconstructions for the Holocene: methodology, mapping and potentials

چکیده
Abstract. Quantitative reconstructions of past land cover are necessary to determine the processes involved in climate–human–land-cover interactions. We present first temporally continuous and most spatially extensive pollen-based land-cover reconstruction for Europe over Holocene (last 11 700 cal yr BP). describe how vegetation has been quantified from pollen records at a 1? × spatial scale using “Regional Estimates VEgetation Abundance Large Sites” (REVEALS) model. REVEALS calculates estimates regional proportions or percentages. applied 1128 across part eastern Mediterranean–Black Sea–Caspian corridor (30–75? N, 25? W–50? E) reconstruct percentage 31 plant taxa assigned 12 functional types (PFTs) 3 (LCTs). A new synthesis relative productivities (RPPs) European was performed this reconstruction. It includes multiple RPP values (?2 values) 39 single 15 (total 54 taxa). To illustrate this, we distribution maps five (Calluna vulgaris, Cerealia type (t)., Picea abies, deciduous Quercus t. evergreen t.) three (open land, OL; trees, ETs; summer-green STs) eight selected time windows. The reliability issues related interpretation results terms landscape openness human-induced change discussed. This is followed by review current use its future potential utility development. data quality primarily determined count (pollen sample, identification, chronology) site number (lake bog, large small, one vs. sites) used analysis (for each grid cell). sites with high-quality will produce more reliable lower standard errors compared low lower-quality data. presented here can be downloaded https://doi.org/10.1594/PANGAEA.937075 (Fyfe et al., 2022).

Pollen-based quantitative reconstructions of Holocene regional vegetation cover (plant-functional types and land-cover types) in Europe suitable for climate modelling.
We present quantitative reconstructions of regional vegetation cover in north-western Europe, western Europe north of the Alps, and eastern Europe for five time windows in the Holocene [around 6k, 3k, 0.5k, 0.2k, and 0.05k calendar years before present (bp)] at a 1° × 1° spatial scale with the objective of producing vegetation descriptions suitable for climate modelling. The REVEALS model was a...
متن کاملLate-glacial and Holocene European pollen data
The European Pollen Database (EPD) is a community effort to archive and make available pollen sequences from across the European continent. Pollen sequences provide records that may be used to infer past vegetation and vegetation change. We present here maps based on 828 sites from the EPD giving an overview of changes in postglacial pollen assemblages in Europe over the past 15,000 years. The ...
متن کاملComparing the Capability of Sentinel 2 and Landsat 8 Satellite Imagery in Land Use and Land Cover Mapping Using Pixel-based and Object-based Classification Methods
Introduction: Having accurate and up-to-date information on the status of land use and land cover change is a key point to protecting natural resources, sustainable agriculture management and urban development. Preparing the land cover and land use maps with traditional methods is usually time and cost consuming. Nowadays satellite imagery provides the possibility to prepare these maps in less ...
متن کاملLand cover land use mapping and change detection analysis using geographic information system and remote sensing
Land cover/land use categories are relevant components in land management. Understanding how land cover/land use change over time is necessary to assess the consequences of humans and natural stressors on the earth’s environment and resources. The aim of the study was to map and monitor the spatial and temporal change in land cover/land use for the periods of 1977, 1991 and 2016 and to predict ...
