Abstract: By taking regional climate system modeling as the research prototype，this paper investigates the key problems of building Geophysical Collaborative Computing Environment（GeoCoEn） based on distributed Web environment by using Peer-to-Peer and mobile agent technology.A multi-layer architecture，including application layer，management layer，execution layer and supporting layer，is designed to support openness，flexibility，extensibility，portability，transparence and other abilities required by collaborative scientific computing environment by integrating P2P and Multi-Agent System（MAS）.

摘要： 以建立区域气候模拟系统为研究原型，探讨利用Peer-to-Peer 技术和移动Agent 技术构建协同地球科学计算环境（GeoCoEn）。基于P2P 和多Agent 集成的多层体系结构，满足了GeoCoEn 对开放性、灵活性、可扩展性、可移植性以及透明性等方面的需求。
