资源信息系统的多层次结构与功能

对应于人口、资源、环境与经济这些复杂系统的信息系统,其结构是多层次的。分别应用于国家宏观决策、地区开发与城市建设。对于空间型与统计型各有侧重。我国资源信息系统起步较晚,进展参差不齐,还不配套。人口数据库缺乏空间型结构:经济数据库属于统计型结构;而海洋环境与资源信息系统则系文献检索的性质。资源信息系统的功能,不应局限于检索、查询,而应走向高层次的分析、模拟与预测。目前已经具备回答决策过程中的一些主要命题,诸如:数据可靠性、资源容量、环境适应性、交通的接近度、工程的可行性和生产的稳定性。正在进一步为建立系统动力模型和专家系统而努力。

MULTI-LEVEL STRUCTURE AND FUNCTION OF RESOURCE INFORMATION SYSTEM

The structure of information system corresponding to a complicated system, which composed of population, resource, environment and economics, is multi-level, respectively applied to national macro decision-making, regional development and urban construction. There are different emphasis on spatial or statistical pattern for different level system. The progress of developing resource information system which started late in China varies in different fields, and current systems are incomplete, of which the population database lacks spatial pattern, economic database is statistical pattern, and ocean environment and resource information system only acts as a literature retrieval system. The resource information system should not be limited to retriving and inquiring, but be expanded to the functions of high-level analysis, simulating and forecasting. Recently, several software systems can answer some major problems in decision-making procedure, such as the reliability of data, the capacity of resource, suitability of environment, the accessibility of transportation, the feasibility of engineering and the stabability of production, and the work developing system dynamic model and expert system are being done.
