摘要:
实现数据文档系统的有效管理必须对数据文档文件进行编码。本文结合湖泊生态系统研究站探讨了数据文档文件编码的若干原则:面向研究对象和目标、唯一性、简单适用性、合理性、可扩充性和规范性,并给出湖泊生态站的分类体系和编码方案。

Abstract:
The archive files of CERN (Chinese Ecosystem Research Network) stations should be encoded for effective management.This paper points out several rules for encoding the archive files: the object-oriented, the uniqueness, the simplicity and suitability, the reasonability, the expendablity and the normality.Based on the object-oriented rule which is the fundamental one, we think it essential to encode the archive files form the viewpoint of the structure and function of ecosystem.The paper puts forth the classification of lake ecosystem research area in the aspects of environment, the structure, material cycle and informatic transmission of ecosystem.A Three-level framework for coding is established and subsquently an 8-bit encoding method proposed: the first and second bits represent the code of CERN stationsj the third and fourth the code of certain field of ecosystem research;and the others the free code.
Key words:  CERN  lake ecosystem  archive files
