摘要:: 以赣南红壤崩岗侵蚀区野外调研孢粉资料为基础,分析了8个表土样品。结果发现:赣南红壤崩岗侵蚀区表土样品孢粉种属类型丰富,共鉴定出131种,统计有效孢粉2 694粒;表土孢粉组合为乔木、灌木、草本、蕨类和苔藓植物,其中乔木和蕨类植物的孢粉占优势,平均分别为48.49%和37.10%,灌木和草本花粉含量较低,平均为3.00%和8.43%。乔木植物中的马尾松(Pinus massoniana)平均浓度为28.0%,蕨类植物中里白厥(Hicriopterisglauca)平均浓度为26.09%,均具有超代表性;植物花粉亚热带特征明显;不同母岩崩岗侵蚀区优势科属种方面存在一定的差异;孢粉组合反映出马尾松、...

Abstract:: Based on the sporopollen data of eight surface samples in red soil avalanching erosion of Gannan region,using LuoPacias sporepollen appraisal system identification of sporepollen, sum up to 131 species, and statistics valid pollen 2 694. The production of sporespollen are rich in species and genus in red soil avalanching erosion in Gannan region, surface sporopollen assemblages: trees ,shrubs,herbs，pteridophytes and moss, but trees and pteridophytes of them are in a dominant position, each average value is 48.49% and 37.10% in which the percentage of shrubs and herbs is a little lower than that of trees and pteridophytes, each average value is 3.00% and 843%. Average thickness values of masson pine in the trees vegetation is 28.0%, average thickness values of the hicriopteris glauca in the pteridophytes vegetation is 26.09%, both of them are superrepresentative. Plant pollen subtropics characteristics are obvious.There are some differences in the dominant familia and genus among different mother rock. The palynological assemblage characters reflect that Pinus massoniana and Hicriopteris glauca can adapt the red soil avalanching erosion and has representativeness. Our objective is to provide and improved information for the study of paleovegetation and paleoclimate and palaeoenvironment etc in Gannan areas. To find pioneer plants for avalanching erosion in Gannan region.
