摘要
本文将GIS空间信息统计分析手段应用于广播电视收视率的评估,以层次分析法为基础进行改进,采用抽样调查的方法确定权重,提出较为合理的基于空间信息统计方法的广电人口覆盖分布模型并加以软件实现。以北京市为研究区域,经导入多个版本人口数据实验,发现这种评估方式较好地修正了传统的仅仅按照面积评估覆盖率的评估模型,对于提高广电行业的信息化管理水平具有一定意义。
This paper applies GIS spatial information statistical analysis tools on radio and television viewing ratings assessment, and has done some improvement based on AHP. Using the sample survey method to determine weights, it gets a more reasonable statistical model for the radio and TV coverage of the population based on spatial information statistical method and implements the model by software. Taking Beijing as the research region, and with imported experimental demographic data, we find that the model significantly improves the traditional assessment, And it is significant for the radio industry to improve the information management level.
