基于GIS的区域土地利用分析评价系统设计

Analysis and Evaluation of Regional Land Use System Design Based on GIS

土地利用分析评价需要分析处理并计算大量数据,同时又需要属性数据与空间数据的严格对应,工作复杂易出错。本文根据土地利用评价的业务流程,结合相关评价理论体系提出了基于GIS的区域土地利用分析评价系统的设计方案。设计方案主要从系统功能和结构方面展开,内容包括系统目标与设计原则、系统总体结构设计、系统功能设计与实现和数据库设计。并充分考虑了系统的构建成本、构建周期和系统的扩展、维护等因素。

Analysis of land use evaluation needs to analyze and calculate the quantity of data,which at the same time need to strictly corresponding attribute data and spatial data,work complexly and make mistakes easily. According to the business process of land use evaluation,combined with relevant evaluation theory system,the design of regional land use evaluation system based on GIS is proposed. The design is mainly from the aspects of system structure and function,including systematic goal and design principle,systematic architecture,systematic function and implementation,and database. And fully consider the costs of the system construction,construction cycle,systematic extension and maintenance and other factors.
