空间决策支持系统(SDSS)作为一个新兴科学技术领域,它以地理信息系统(GIS)和决策支持系统(DSS)为基础,以解决生产实践问题为目标,目前已经被广泛应用于水利、交通、农业等行业。本文主要介绍SDSS和模型之间关系的思想设计,以及实现用于解决南水北调项目中处理移民安置问题的空间决策支持系统。处理移民安置的问题比较复杂,其中移民安置、移民安置区环境用量分析以及移民安置区土地资源评价等问题都与空间信息有关,要解决这些问题需要对各种数据信息、空间信息进行综合的宏观分析和深层次挖掘分析,结合专业知识设计可行的处理模型,并运用计算机技术加以实现。
Spatial Decision Support System (SDSS), as an emerging science and technology field, is based on Geographic Information System (GIS) and Decision Support System (DSS) and aims to solve production problems. It has been widely used in water conservancy, transportation, Agriculture and other industries. This paper introduces the conceptual design of the relationship between SDSS and models and the implementation of a spatial decision support system to address resettlement issues in the South-to-North Water Diversion Project. The problems of handling resettlement are complicated. Among them, the resettlement, resettlement area environmental amount analysis and land resources evaluation are all related to the spatial information. To solve these problems, it is necessary to comprehensively analyze various data and spatial information Analysis and deep mining analysis, combined with professional knowledge to design feasible processing model, and the use of computer technology to be achieved.
