Based on the U-series dating and sporo-pollen analysis, this paper presents a discussion on the paleovegetation and paleoclimate of the Buqu Basin and its adjacent regions during the interval 88.
结合孢粉分析结果 ,本文探讨了青海省西部地区通天河及布曲流域晚更新世早中期的古植被与古气候。
A preliminary study of ancient vegetation in Xishui Swan Pool;
习水天鹅池古植被的初步研究
In this paper, the vertical evolution characteristics of palaeo-vegetation, palaeoclimate and palaeo-environment in Tuha basin are probed through the study of the Jurassic palynoflora, special lithology, and the distribution law of elements and clay mineral in argillaceous rock.
通过吐哈盆地侏罗系孢粉植物群、特殊岩性、泥质岩中元素、粘土矿物分布规律研究,探讨了古植被、古气候及古环境的纵向演化特点,认为区内侏罗纪古气候为:早侏罗世至中侏罗世早期区内气候为温暖潮湿的亚热带,局部有干旱趋势;中侏罗世中晚期半潮湿、半干旱的温带-亚热带气候;从中侏罗世末期开始转为炎热干旱的亚热带气候。
This paper presents the high-resolution sequence of vegetation change of the last inter-glacial period in Xishan Mountain,Beijing by pollen analysis and thermoluminescent dating technology with reconstruction of the palaeo-vegetation and palaeo-environment of this region.
末次冰期—间冰期气候旋回研究是过去的全球变化(PAGES)研究的三大重点之一,通过孢粉分析和热释光断代建立了北京西山末次间冰期植被的演化序列,研究了该地区古植被与古环境的演化规律。
The fossil plants were very rich in different strata of geological age, such as Bennettites, Baiera, Ginkgo, Cycas and Gigantopterides, etc.
地层中存在大量的古植物化石,如本内苏铁、银杏、苏铁等就极为丰富,种子蕨特别是大羽羊齿尤为突出,而且在白垩纪晚期至第三纪的广东(及广西西南)地层中,存在着丰富的现代植物的化石或化石孢粉组合,如朴树、桦木、鹅耳枥及松、冷杉、雪松等,还有其它阔叶树和针叶树,所有这些都与广东复杂的地质发展史密切相关,它预示着广东植物区系可能起源于亚热带山地,而且广东无疑是华夏植物区系或东亚植物区系的萌芽和发源地之一。
Research on the Microplants in Late Precambrian of China;
中国晚前寒武纪微古植物研究
In order to probe the relation of the fossilmaterials and the trend of environment change during the Luotuolingian and Xiamalingian stages, Qinbaikouan Period, this paper discusses the paleobiological evidence from three aspects: ① the distribution of microplants .
因此,笔者认为青白口纪微古植物和宏观藻类化石在区域丰度和形态变化方面与水深、水动力条件及水团性质等环境因素的变化密切相关。
