基于GIS的西安市图书馆空间分布特征分析

基于ArcGIS空间分析工具,用标准差椭圆、核密度分析和平均最近邻指数对西安市图书馆的空间分布特征做了量化分析,结果表明:(1)研究区内图书馆的分布呈现明显的集聚特征,主要分布区内呈“三核心、多点”分布;(2)图书馆的分布呈东北—西南走向;(3)图书馆和高等院校的分布有较强的相似性。本文通过研究西安市图书馆的空间分布,以期为未来图书馆的长远规划和布局提供借鉴,同时也为人们选择最佳的图书借阅场所提供参考。

Based on ArcGIS spatial analysis tool,the spatial distribution characteristics of Xi'an libraries are quantitatively analyzed by standard deviation ellipse,kernel density analysis and average nearest neighbor index.The results show that:(1)the distribution of Libraries presents obvious agglomeration,and the main distribution area presents"three core and multi-point";(2)The distribution of libraries is northeast southwest;(3)There is a strong similarity between the distribution of libraries and universities.This paper provide reference for the long-term planning and layout of the library in the future,and also provide reference for people to choose the best book borrowing place.
