川北若爾蓋高原紅原泥炭剖面孢粉記錄的晚冰期以來古氣候古環境的演變The research during the prehistoric period is a base and difficult palynology which provides numerous evidences plays an important role and makes great contributions to the research on holocene environment changes
其中全新世以來史前時期是全新世環境變化研究的基礎和難點。孢粉學在全球環境演變研究中提供了大量證據，發揮了重大作用，成果顯著。According to the re - analyses on pollen assemblages and archeological evidences in the site and related documents, this paper reconstructs the sequence of fossil pollen - pollen - vegetation - paleoclimate during the prehistoric period, emphatically discussing environment changes, the space - time distributed law on archaeological sites, the origin of culture fault and formation mechanism
本文根據孢粉學和考古學證據，結合相關文獻資料，從古地理學、考古學、歷史學等綜合研究的角度，重建史前時期化石花粉? ?孢粉植被? ?古氣候環境的演變序列，著重探討太湖流域新石器時期的環境變遷與古文化遺址的時空分佈規律、文化斷層的成因及其機制。The neogene is a key stage of terrestrial environmental evolution in yunnan. three stratigraphic sections including luhe ( late miocene ), yangyi and longling ( late pliocene ) were selected to reconstruct vertical landscape of paleovegetation in these areas, based on palynological data. according to principle of the coexistence approach, seven quantitative paleoclimatic parameters of each deposit area were obtained by using meteorological data ( 1951 - 1980 ) of the distribution area of extant taxa found each palynoflora in china
晚第三紀是雲南地區環境演變過程中的關鍵地質歷史時段，本論文以晚第三紀晚中新世（呂合） 、晚上新世（羊邑和龍陵）地層中的孢粉為研究對象，結合同層位大化石植物證據，參照現代植被，恢復了雲南三個化石出產地區的古植被垂直分佈景觀，並定性地描述了古氣候；同時運用共存分析方法（ theco - existenceapproach ）定量化地重建了三個地區的古氣候參數值；初步推測了沉積地可能的古海拔。By spore - pollen analysis of 10 samples and combining the features of spore - pollen assemblage and climatic environment, the features of evolvement of climatic environment of this sedimentary area since the middle holocene are obtained
本論文還選取其中10個樣品進行了孢粉分析，並結合鄰近地區的孢粉組合特徵和氣候環境特徵，總結出該沉積區中全新世以來氣候環境演變特徵。Will be discussed in this paper, based on the analysis of the sedimentary facies characters and paleo - environment indexes such as clay mineral, chemical element and spore - pollen of the sediment samples collected from the middle - part of the stratigraphic profile including upper and lower cultural layers of the dongfang plaza cultural site
依據對遺址區剖面中段包含了上下兩個文化層沉積樣品的沉積相特徵以及粘土礦物化學元素和孢粉等古環境指標的分析，探討了2 . 6萬年前後至1 . 4萬年前後古環境的演變過程。Based on the above analysis, the other factors reflecting the features of environmental evolvement and the spore - pollen assemblage of huabei plain, the features of environmental evolvement in the south coastal plain of laizhou bay since the middle holocene is summarized
根據上述分析研究，再綜合萊州灣南岸平原其它反映該研究區環境演變特徵的要素，以及鄰近的華北平原的孢粉組合，分析總結出萊州灣南岸平原中全新世以來的環境演變特徵。分享友人
