It utilized factor analysis and regression analysis ofthe multi-statistics to make the quantitative analysis on a great deal of core proxies in the North Indian Ocean and Indonesian Archipelago areas, and acquiredthe exact conversion relations of paleoceanic environment parameters (sea surface temperatureand salinity) and proxies. Then it made the change curve which can show the changes of paleo-ceanic environment parameters (sea surface temperature and salinity) which followed the changesof depth and provided the contrast between paleoceanic environment parameters of different coreson the landscape orientation. This paper supplied a more scientific and exact method for resumingthe paleoceanic environment on paleoceanography research.

本文阐述了以古海洋学数据库系统数据为基础的古海洋学多元统计分析模型，利用多元统计学中的因子分析和回归分析技术对北印度洋以及印尼多岛海地区大量岩芯的替代指标做定量分析，求出古环境参数与替代指标的精确转换关系，从而做出各岩芯处古环境参数随深度的变化曲线，提供不同岩芯在横向上的古环境参数对比，为古海洋学研究中恢复古环境提供了一种更科学更精确的方法。

Each unitis of different biotic characters and displays different features of seawater composition during the time. 2 The black unit including a biotic extinction was caused by oceanic anoxic event. Crisis that deepwater keeled foraminifera encountered represents a ferocious anoxia in deep marine environment . Biotic recovery in gray unit reflects gradually improved marine circumstance. What the biotic extinction at the C/T boundary in black unit reflects an environmental mutation, whereas the gradual biotic change characterize the recovery of marine dissolved oxygen environment in a stepwise process. The red unit is the result of oxic deposition and characterized by extremely abundance of foraminiferal faunas, which reflects a high-oxidized marine circumstance. 3 As the most ordinary biotic index in paleoceanography researches, foraminifera represent anexcellent environmental indicator in this paper.

三套岩层表现出不同的生物特征，并指示出当时海水的不同性质。2黑层段是大洋缺氧造成的结果，生物大量灭绝，深层水具旋脊有孔虫的所遭受的危机反映出当时海洋深层水体严重缺氧的特征；灰层段中生物的恢复反映出海洋环境自缺氧事件之后的逐步改善过程，与黑层段反映的C/T 界线处生物绝灭反映的环境突变不同，灰层段生物特征的渐变指示出当时海洋溶解氧环境的恢复也是一个逐步的过程；红层段属于富氧沉积的产物，特征是有孔虫生物的极度繁盛，反映的是一种高氧化性的海洋环境。3有孔虫作为古海洋研究中最常用的生物指标，在本文研究中显示了良好的环境指示性。
