According to the basic principle of sedimentary geochemistry , two geochemical sections from dongying sag of bohai bay region and turpan basin were selected as the standard models of deep - water rift - subsidence basin and shallow water coal measure basin , respectively 结果表明，该盆地侏罗系地层元素特征与东营凹陷很相似，由此推知其古环境在更大程度上倾向于东部深水断陷湖盆。

It is important to study salawusu stratum using paleomagnetism method , to give some magnetic proof in age range , stratum correlation , paleoenvironment and paleoclimate , to test former research result . this paper has done systemic paleomagnetism investigation , at dishaogouwan section its magnetic character is : susceptibility value is relatively high and its curve fluctuates little , magnetic mineral is mainly magnetites . the susceptibility ams ellipse is oblate 随着古地磁学及其分支学科的发展和成熟，以及在一些古人类遗址研究中的成功运用，对萨拉乌苏地层进行系统的地磁学研究，从磁学的角度提供一些年代归属、地层划分与对比、古环境、古气候方面的成果，对近年来的研究成果进行印证或检验，为研究的焦点问题提供古地磁学依据很有必要。
Through the research of paleo - environment change and process with regard to east asia monsoon environment system , loess , karst , ice core , lakes , paleo - oceanography , the impact of human activities over terrestrial ecological system , and marine ecologic dynamics , they rebuild the natural environment evolution regularity of east asia , thus actively and effectively push forward the research of global change study 通过东亚季风环境系统、黄土、岩溶、冰芯、湖泊、古海洋学和人类活动对陆地生态系统影响以及海洋生态动力学等方面，开展古环境变化和过程研究，重建了东亚自然环境演化规律，积极而卓有成效地推动了全球变化研究。
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 依据对遗址区剖面中段包含了上下两个文化层沉积样品的沉积相特征以及粘土矿物化学元素和孢粉等古环境指标的分析，探讨了2 . 6万年前后至1 . 4万年前后古环境的演变过程。
Through investigating and analyzing cave deposits samples at tuozidong of tangshan , nanjing , combining previous research results and geological history of the tangshan area , we discuss the geochronology , depositional processes and modes of the tuozidong cave deposits , and logically elaborates on its paleoenvironments , geomorphology , paleoclimate and biological evolution at tuozidong 摘要通过对南京汤山驼子洞洞穴堆积观察描述和样品分析测试，结合前人研究成果和汤山地区地质地貌演化的历史，讨论了驼子洞堆积的时代、堆积过程和方式，井对其蕴含的构造、地貌、气候和生物进化等古环境信息进行了合理的挖掘。
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 本文根据南黄海中部泥质区和东海中陆架的两个钻孔岩芯的古生物、 ams ~ ( 14 ) c测年、浅地层剖面等，参考qc _ 2 、 dz _ 4成果及标准氧同位素曲线探讨了黄东海陆架晚第四纪古环境演化、底栖动物群特征、古气候、冰后期以来气候事件、古水团、沉积速率、古水深、沉积物源、海平面平均上升率，讨论目前中国东部海平面上升的状况、温室效应及海岸带保护。
The global change study is one of the most spectacular and interesting environment scientific questions in the 1990 s . the message of global change stores in tree rings , ice core , loess , underground water , lake sediment and deep sea sediment , all these proxies record the information of global change . with the advances in stable isotope techniques , the isotopic tracer records the message of climatic variation and becomes a powerful tool that can understand paleoenvironment reconstruction and modern environment changing 全球变化研究是90年代以来最为引人注目和关切的环境科学问题之一。全球环境变化的信息储存于树轮湖泊冰芯黄土地下水和海洋沉积物等载体中，随着稳定同位素技术的发展，同位素示踪剂指示环境变化的信息，成为了解古环境再造和现代环境信息变化的一个强有力的工具。
The result of analysis shows that the climate of the period during which these strata were formed was mainly dry and cold , and the pollen of herbs is predominant . in the later part of this period the temperature and humidity increased a little , especially between the two cultural layers there was a short but clear section of wet and warm climate and a temperate forest steppe landscape existed 古环境分析表明，文化层出现前后的这一段时期，一直以干冷气候为主，草本花粉占绝对优势，中后期温湿度有所增加，尤其上下文化层之间曾有一个短暂而明显的较为温湿的时期，出现了温带森林草原景观。
From sedimentology symbol such as rock assembled , sediment gradus , sandstone grading analysis , protogene sedimentary structure , ichnofossile and logging facies etc and palaeoenvironment background , it is confirmed that shen84 - an12block s34 segment is braid river delta system , not fan delta system ( abrupt slope ) . then it can be more partition as braid river delta plain sedimentary assembled , delta front sedimentary assembled and prodelta sedimentary assembled on core and log assembled . and delta plain sedimentary assembled can be identified four microfacies : braided distributary channel , crevasse splay , overbank deposits and interdistributary bay 沉积微相研究是储层非均质性研究的基础，研究区有丰富的岩芯资料和测井资料，通过岩石组合、沉积韵律，砂岩粒度分析、沉积构造、古生物遗迹和测井相等沉积学标志，结合古环境背景，确定沈84 ?安12块s _ 3 ~ 4段为辫状河三角洲体系，而不是前人所认为的扇三角洲(陡坡型)体系，在岩芯和测井组合上可进一步划分为辫状河三角洲平原沉积组合、三角洲前缘沉积组合和前三角洲沉积组合，其中三角洲平原沉积组合又可识别出辫状分流河道、决口扇、分流河道边部和分流间湾四种微相类型；三角洲前缘沉积组合识别出水下分流河道、水下分流河道边部和分流河口坝三种微相。
