Abstract:

As the interface of the users and grid applications，grid portal shields the complex grid environment，provides the users with convenient ways calling grid resources and plays an important role in improving the usability of grid technology. This article uses analytical method of mapping knowledge domains，takes CNKI as the data source and makes co-word analysis as the basic method. It utilizes the mutations detection algorithm of CiteSpaceⅡ to detect the research focuses and research frontiers of domestic grid portal，generates hybrid network mapping with co-occurrence of terms and related authors of research focuses and research frontiers，combines quantitative analysis with qualitative analysis and analyses the research themes and related researchers of domestic grid portal in its development process objectively and comprehensively. And then，it reveals the development process of grid portal in China. Firstly，in recent years，the research of domestic grid portal mainly focuses on four aspects which include research category，research purpose，application technology and research application. Secondly，the domestic grid portal field mainly derives four research frontiers which are the design of system structure of grid portal for finite element analysis，science data，work flow system and grid portal security. Finally，the research focuses and research frontiers of domestic grid portal evolve and advance mutually.

Key words: Grid portal, Mapping knowledge domains, CiteSpaceⅡ
