Benthic foraminifer fauna, ams14c dating and acoustic sub - bottom profile was analyzed in the core ey02 - 2 and ey02 - 1 drilled from the muddy deposit in the middle southern yellow sea and the mid - shelf of north east china sea. considering the results of core qc2 ? dz4 and the standard oxygen isotope curves, we discussed the late - quaterenary paleo - environment evolution, benthic foraminifer fauna, paleo - climate, the climate events and water mass in postglacial period, average sedimentation rates, paleo - water depth, origin of sediments, average sea level rise rate in the shelf of south yellow sea and east china sea. at last we discussed the condition of sea level rise in the east china, green house effect and the protection of coastal zone
本文根據南黃海中部泥質區和東海中陸架的兩個鉆孔巖芯的古生物、 ams ~ （ 14 ） c測年、淺地層剖面等，參考qc _ 2 、 dz _ 4成果及標準氧同位素曲線探討了黃東海陸架晚第四紀古環境演化、底棲動物群特徵、古氣候、冰後期以來氣候事件、古水團、沉積速率、古水深、沉積物源、海平面平均上升率，討論目前中國東部海平面上升的狀況、溫室效應及海岸帶保護。This work carries out a temporal - spatial analysis and comparison in facial pattern, grain - size, and susceptibility of the sediments of the hunshandake sandy land ( hsl ) on the basis of studies of more than fifty geological sections, a number of samples collected from surface sands as well as results derived from previous studies. the preliminary results of this work provide new environmental information of the working area, which makes it possible to have a brief discussion about the evolution of the hsl since the late glacial epoch. this work can be summarized as the followings
晚冰期，渾善達克沙地全面擴張，達到了沙漠化最大規模，剖面中的古風成砂是最直接的證據，此時氣候乾冷；全新世早中期，渾善達克沙地成壤比較好，是一個大面積成壤期，相當于全新世適宜期，此時氣候暖濕；全新世晚期，渾善達克沙地沙漠化正過程加強，在沙地各剖面上普遍發育風沙沉積，氣溫較乾冷；目前：渾善達克沙地為另一成壤期，成壤作用相對于適宜期較差，氣候乾暖。Paleoclimatic and paleoenvironmental evolution since the late glacial epoch as recorded by sporopollen from the hongyuan peat section on the zoig 234 ; plateau, northern sichuan, china
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Setenaly according to the analyses from selected profiles, we know that, it is cold and dry in this region during the early holocene when east asian winter monsoon ' s influence is obvious, so, it is a transition period from sand deposit to sandy soil deposit, when the layers become thinner gradually from north to south. during middle holocene, it is warm and humid, influenced evidently by east asian summer monsoon, so, it is an obivious pedogenesis, when there are generally well - developped holecene palaeosol ( so ) from north to south, and the pedogenesis in the south is better than that in the north, the soil is also thicker than that of the north. from late holocene to now, the climate changes to be dry and cold, but its changing scope is smaller than that of last glacial period
2 、就所選剖面分析來看，本區在全新世早期氣候回返，相對較寒冷乾燥，東亞冬季風影響較明顯，此時為沙層堆積向砂質土壤過渡，自北至南堆積的沙粒漸細；全新世中期氣候溫暖濕潤，東亞夏季風影響顯著，此時為明顯的成壤期，表現在自北至南普遍可見發育較好的黑壚土層，且南部的成壤作用比北部好，土壤的厚度也要大；全新世晚期至今，氣候向乾冷方向轉化，但變化幅度遠小於末次冰期。The carbonate content varied from 0 to 34. 55 % in the column of drilling core ey02 - 2, the higher carbonate content related to materials of modern and old yellow river in postglacial period, while the peak carbonate content related to the shell fragment in the sediment, the dissolved cycle appeared to be the carbonate dissolved cycle of the atlantic mode
Ey02 - 2孔柱樣碳酸鹽含量在0 - 34 . 55之間變化，呈現大西洋型caco _ 3溶解旋迴，冰後期以來碳酸鹽高含量與高碳酸鹽的現代黃河和廢黃河物質有關，而中晚更新世碳酸鹽極高含量與貝殼含量有關。Late - glacial and holocene climate change recorded in loess profile in weibei loess tableland
