摘要

过去全球变化（PAGES）是IGBP的核心计划之一。在同国际PAGES计划研究内容对等的前提下，我国的过去全球变化研究既应发挥国内原有工作的传统优势，又应照顾到东亚古环境演变的独特性和填补全球资料空间缺口的需要。根据这一原则，本文对我国相应于PAGES计划的具体研究内容提出了若干建议。

Abstract

    PAGES is one of the core projects of IGBP. China has an advantage in studying the past environmental changes due to a wealth of natural archives and historical records. Major recommendations are given in the present paper,focusing on the following questions:
    1. Environmental change of East Asia since 130 ka BP;
    2. Climate and environmental changes of China in the past 2000 years;
    3. Climate change of china in the last 2000 years;
    4. Interaction between human activities and environment;
    5. Mapping of the palaeo-data at selected time slices;
    6. Model experiments to test the role of various forcing mechanisms in the past changes on different time scales.
    Priority has been noted for each question mentioned above based on the proxy sources and the traditional research fields.

Key words： PAGES; China; Recommendation.
