Based on the high-resolution analysis of planktonic foraminiferal isotope and organic carbon of 91 sediment samples from two box cores located respectively in the southern and northern slopes of the South China Sea, the changes of sea surface temperature and paleoproductiviy of the past 2400 years were reconstructed. The sea surface temperature and the depth of thermocline varied in different stages during the late Holocene, with some short-term climate events such as the Little Ice Age.

This dissertation, based on (1) field investigations and observation along Jiangsu coastal environment (including: sea bottom and tidal flat sediment sampling, water depth, salinity, current velocity and direction, core drilling and so on);(2) integrative laboratory analyses of micropalaeontology, sedimentology and computer-processed mathematical statistics on over 300 samples and about 100 thousand foraminifera tests, try to find and formulize the relations between foraminiferal thanatocoenose and environment.

本文的写作基础是：通过野外进行的海岸环境调查和测量（主要调查项目有：水深、盐度，流速、流向、含沙量、底质采样、浅地层地震剖面仪探测、潮滩钻孔取样、潮滩探槽的挖掘与沉积物取样、观测等等）取得了环境参数和大量样品；在实验室运用微体古生物学、沉积学、数理统计与计算机分析相结合的方法，对所采集的现代表层沉积物和钻孔岩芯样品共计三百多个进行了分析研究，鉴定统计有孔虫标本十万余枚，研究有孔虫埋葬群特征与环境参数之间的定性-定量关系。

Based on the whole, dynamic and synthetical basin analytical methods, the structural characteristic of the South Ordos basin in the Late Mesozoic and the Cenozoic is researched with the data of seismic, geological and former achievements. In order to discuss deeply to the geodynamical background of Ordos basin and study the dominant factors controlling the sediment evolvement of the basin, we discusses the evolvement of basin from an even more extensive view.

采用&整体、动态、综合&的盆地分析方法，根据地震、地质等资料，结合野外地质及前人研究成果，对鄂尔多斯盆地南部中-新生代以来后期改造特征进行了研究，深入探讨控制鄂尔多斯盆地形成演化的地球动力学背景，研究盆地构造沉积演化的主控因素。

The results indicated that (1) the 147Pm, 141Ce and 147Nd had strong adsorptivity in soil, so they were hard to transfer and easily accumulated in soil or sediment;(2) all the organisms (5 aquaties and 4 eatable plants) tested showed apparent 147Pm concentrating capabilities;(3)the residues of 147Pm, 141Ce and 147Nd were unevenly distributed in the animal's viscera and tissues, higher residues were found in bone, marrow, eye, brain, heart, adipose and testis, showing selective accumulation;(4) with intraperitioneal dosing of Nd or Ce 200mg ·kg -1 apparent inhibition to gonadial hormone secretion in mice was found and with 200 and 800mg·-1 of Ce added in feed, the malformation rate of spematozoon showed higher.

综合研究结果表明： 14 7Pm、14 1Ce和14 7Nd在土壤中具有强的吸附性，而且难以迁移，易于在土壤和底泥中积累；( 2 )供试的 5种水生生物、4种陆生食用植物对14 7Pm均具有明显的富集性；( 3) 14 7Pm、14 1Ce、14 7Nd在动物体内脏器和组织间呈不均匀分布，在骨骼、骨髓、眼、大脑、心脏、脂肪和睾丸中残留量较高，表现了明显的选择性蓄积；( 4 )一次性腹腔注射2 0 0mg·kg-1的Ce和Nd对小鼠性腺激素的分泌有明显的抑制作用，以 2 0 0和80 0mg·-1的Ce随饲料摄入对雄性小鼠精子畸形率明显升高。
