Abstract

ABSTRACT Vegetation reconstruction from fossil pollen records depends on an adequate understanding of the relationship between modern pollen-rain and the extant vegetation. Modern pollen assemblages, that reflect the extant vegetation of an area, have been documented through the palynological analysis of 30 modern moss cushions from Rourkela, Sundargarh District (Odisha State), India. The study demonstrated the dominance of non-arboreal pollen taxa (NAPs; herbs) over the arboreal pollen taxa (APs; trees and shrubs). Tree pollen taxa, among the APs, contributed with an average sum of 23% of the total pollen sum, whereas shrubby taxa have an average pollen sum of 17%. Among the herbs (NAPs), Poaceae is the dominating herbaceous taxon in the total pollen-rain, whereas Cerealia and other cultural pollen taxa are the other prominent herbaceous taxa of the pollen-rain, besides Asteroideae. The overall pollen assemblages suggest an open nature of the forest around the study area. Insights into pollen source, representation (production and dispersal), transport and preservation of certain taxa around the study area have been also provided. Comparison of the pollen assemblages in present study with the pollen assemblages from other areas (especially from central India) has been also been made in order to have a broad overview of such study around the study area. The present study could improve our understanding of the modern pollen-rain/vegetation relationship and further aid in calibration and interpretation of the fossil pollen records.

印度奥里萨邦Rourkela（Sundargarh区）现代花粉与植被关系的初步研究与比较

根据花粉化石记录重建植被取决于对现代花粉雨和现存植被之间关系的充分理解。通过对印度Sundargarh区（奥迪沙州）Rourkela的30个现代苔藓垫的孢粉学分析，记录了反映该地区现存植被的现代花粉组合。该研究表明，非树栖花粉类群（NAPs；草本植物）比树栖花粉分类群（AP；树木和灌木）占优势。在AP中，树木花粉分类群的花粉总数平均占花粉总数的23%，而灌木分类群的平均花粉总数为17%。在草本植物（NAPs）中，禾本科是花粉雨中占主导地位的草本分类单元，而禾谷属和其他栽培花粉分类单元是除小行星科外花粉雨中其他突出的草本分类群。总体花粉组合表明研究区域周围的森林具有开放性。还提供了对研究区域周围某些分类群的花粉来源、表现（生产和传播）、运输和保存的见解。还将本研究中的花粉组合与其他地区（特别是印度中部）的花粉组合进行了比较，以便对研究区域的花粉组合研究有一个大致的了解。本研究可以提高我们对现代花粉雨/植被关系的理解，并进一步帮助校准和解释花粉化石记录。缩写：AP：乔木花粉；NAPs：非树栖花粉；TPS：花粉总量；ISM：印度夏季风；SWSM：西南夏季风；BSIP：Birbal Sahni古科学研究所
