摘要
土地适宜性评价是将评价原始资料进行分析处理得到土地相对于特定用途的适宜程度。针对土地适宜性评价必须按照一定的流程展开工作的特点,文章将面向数据流的系统分析和设计方法运用于土地适宜性评价中,通过对土地适宜性评价系统数据分析,结构设计,最终采用全组件式G IS软件SuperM ap Ob jects2003实现土地适宜性评价系统,从而提高了土地适宜性评价的效率和准确性。
Land suitability evaluation refers to analyzing and processing original data to find the land suitability level in contrast to its particular use. According to the feature that land suitability evaluation must be carried out under a certain process, the paper applies system analysis and design based on data flow to land suitability evaluation. By data analysis and structure design, the paper adopts GIS software-SuperMap objects 2003 to realize the evaluation system so as to improve the efficiency and accuracy of the evaluatin.
