区域可持续发展是指区域自然环境容量可以不断满足人类生活质量保障的社会发展状态，要实现这种可持续发展，就必须评价区域的可持续性，EIS／RSD是在windows NT环境下开发的一个以遥感专题信息作为重要信息来源，具有综合分析和空间制图显示能力的区域可持续发展评价息系统，该文阐述了EIS／RSD的系统目标，技术路线，概念模型，系统功能，使用方法和结果表达方式。

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.
