Abstract: Mechanisms of natural ecological systems combined with technology of mobile agent were used to design a novel Ecological Grid Platform. We implemented bioentities with the characteristics of mobile agent and biolo gical individual, and designed their behavior algorithms on the platform. The Bioentities can offer effectively various kinds of grid service and applications by service emergence and evolution. Accordingly it can solve some problems in current grid computing architecture, such as intelligence, agility, selfextension, adaptability.

Key words: grid computing, ecological system, emergent computing, grid services
