SATELLITE MODIS-AND MODERN POLLEN-BASED QUANTITATIVE VEGETATION COVER SIMULATION IN CHINA

Gushengwu xuebao (2009)

Zhuo Zheng Yanwei Zheng Huang Kangyou Jinhui Wei Chuanxiu Luo

Based on a set of 1 127 modern surface pollen assemblages from China and NASA MODIS 500m resolution image,this paper presents the preliminary reconstructions of vegetation cover of China using modern analog technique. Trees,herbs and bare land coverage data were extracted from MODIS images. A total of 64 pollen types was selected for estimating the vegetation cover. The modeling result shows that the evaluated vegetation covers based on pollen data were coherent with the observed value of MODIS,and the correlation coefficient is reliable and significant:the bare cover is as high as 0.99,the tree cover is 0.97 and the herbs 0.95. As a result,the vegetation cover can be accurately simulated with MAT technique based on Chinese modern surface pollen dataset. Furthermore,the simulated result shows a concordant spatial distribution in the vegetation cover with Chinese vegetation map. The characteristic pollen types corresponding to the high tree cover samples include mainly:Pinus,Castanopsis,Quercus,Dacrydium,Alnus,Betula,Myrica,Podocarpus,Abies,Mallotus,Ericaceae,Ilex,Tsuga,Symplocos,Liquidambar and Platycarya. The typical pollen taxa in the highest herbaceous cover samples are Cyperaceae,Artemisia,Chenopodiaceae,Poaceae,Asteraceae,Rosaceae and Fabaceae. And the bare cover is characterized by Ephedra and Chenopodiaceae.

East Asian pollen database: modern pollen distribution and its quantitative relationship with vegetation and climate

Journal of Biogeography (2014)

Zhuo Zheng Jinhui Wei Kangyou Huang Qinghai Xu Houyuan Lü

Abstract Aim Our aims were to provide new pollen data for establishing a sub‐continental surface pollen database (East Asian Pollen Database, EAPD) and to study relationships between vegetation and climate. Location The sample sites covered most regions of East Asia, including China, Mongolia, the Russian Far East, Vietnam, Cambodia and Thailand. Methods Data quality control procedures were applied, including taxonomic standardization, removal of duplicates, and adjustment of geographical coordinates. Vegetation types and climate parameters were assigned to each sample. Modern pollen distribution maps were drawn using circle scattergrams. The plots of pollen percentages versus climate variables allowed quantitative estimates of climate values. The modern analogue technique (MAT) was used to predict modern biomes and climate parameters. Results Pollen assemblages extracted from 2858 sites were used to model the geographical distribution of selected taxa and their relationships with climate. For most taxa, the reconstructed range fitted the observed geographical distribution rather well. Arboreal pollen (AP) and Pinus dominated the transition zone between forest and steppe. Use of the MAT revealed that the predicted and observed biomes matched in 71% of the cases. The warm temperate evergreen broadleaf forest had the best agreement between predictions and observations. Climate values reconstructed using MAT were highly correlated with observed values in January temperature. The correlation coefficient of the temperature variables ranged from 0.799 to 0.930 and was as high as 0.939 for precipitation. Main conclusions This paper documents a new modern pollen database for East Asia and makes the data readily available. The reconstructed biomes and climate variables are significantly correlated with the observed values, thus demonstrating the utility of the pollen database for future multiscale palaeoenvironmental studies.

Rapid climatic variability in the west Mediterranean during the last 25 000 years from high resolution pollen data

Climate of the past (2009)

Nathalie Combourieu‐Nebout Odile Peyron Isabelle Dormoy Stéphanie Desprat Célia Beaudouin

Abstract. High-temporal resolution pollen record from the Alboran Sea ODP Site 976, pollen-based quantitative climate reconstruction and biomisation show that changes of Mediterranean vegetation have been clearly modulated by short and long term variability during the last 25 000 years. The reliability of the quantitative climate reconstruction from marine pollen spectra has been tested using 22 marine core-top samples from the Mediterranean. The ODP Site 976 pollen record and climatic reconstruction confirm that Mediterranean environments have a rapid response to the climatic fluctuations during the last Termination. The western Mediterranean vegetation response appears nearly synchronous with North Atlantic variability during the last deglaciation as well as during the Holocene. High-resolution analyses of the ODP Site 976 pollen record show a cooling trend during the Bölling/Allerød period. In addition, this period is marked by two warm episodes bracketing a cooling event that represent the Bölling-Older Dryas-Allerød succession. During the Holocene, recurrent declines of the forest cover over the Alboran Sea borderlands indicate climate events that correlate well with several events of increased Mediterranean dryness observed on the continent and with Mediterranean Sea cooling episodes detected by alkenone-based sea surface temperature reconstructions. These events clearly reflect the response of the Mediterranean vegetation to the North Atlantic Holocene cold events.
