Abstract:

The present paper is dealing with the main idea of the framework of CAIS and studies some problems about its establishmcnt on the basis of the theories of system,information and control,and considering the realistic needs of Chinese Antarctic scientific research and the current international status. Since research on Antarctic science is a special field that highly depends on international cooperation,it must provide strong and accurate support to the study of two scientific priorities-the role of the Antarctic in global change and projects on Antarctic scientific singularity,which are involved in many international global research programs. The urgent-to-be-solved problems are how to comply with the trend on international Antarctic data management to form a satisfactory open atmosphere, how to utilize Antarctic data efficiently, how to make timely interchange of Antarctic data between concerning countries and how to make Antarctic data management systematic,network-fit and standardized. The establishment of CAIS is a kind of applied research using information techniques under the direction of behavior science and on the basis of system science theory. The present paper tries to describe the architecture of CAIS along the line of concept-theory method application. It discusses the mutual supplementary relation between the establishment of CAIS and Antarctic data management,describes models of conceptual structure and framework of CAIS,analyzes CAIS' main structure and composition,studies the hierarchical and correlational properties of the framework. Considering problems that may weaken CAIS, it gives some needed techniques,research methods, basic principles and development strategies, pointing out that the first practitional objective of CAIS is to develop Antarctic-Scientific Data Directory and Antarctic key words according to international ADIF,and that the construction of CAIS must be fixed on speeding the exploitation of Antarctic data resources, reflecting and developing synchronously with international dynamics, in order to make the work of CAIS efficient,systematic,economical and reasonable. The establishment and dynamic optimization of CAIS will be a social system engineering project that will last across the turn of the century.
