In the last three decades,sustainable development(SD)has been proposed and developed as a new development model.In China,SD has been confirmed as one of the two basic strategies(the other one is"Developing through science & education")for national development.We define regional sustainability development as the continuous support of human quality of life within a region's ecological carrying capacity.To achieve regional sustainability development,one must first assess the current situation.Until now,studies on SD have been mainly focused on two domain,one is the concepts and theory of SD and the other is the effectively realizing processes of SD,while few studies were carried out on evaluation methods of SD.Recently the application of Geo-spatial information technology in SD assessment,has gained great attention,mainly because the conventional statistic methods cannot satisfy the requirements of SD assessments. A concept-ual model of regional SD assessment,using high spatiod-temporal resolution remote sensing satellites as an important data sources,was built based on some essential achievements such as Human Development Index(HDI)and ecological footprint.In the conceptual model,'development'and 'sustainability' were used as two primary criteria to evaluate the regional SD situation. Evaluation Information System for Regional Sustainable Development (EIS/RSD) was developed based on the above-mentioned conceptual model. The system has a number of application models,which can be used for further analysis of original data. The analysis result can be displayed using map and chart. This paper presents the aim,developing scheme,conceptual model,function and assessment method of evaluation information system for regional sustainable development.
