热点分析在国情监测数据分析中的应用初探

The Application of Hotspot Analysis in National Geographic Condition Monitoring Data Analysis

进行地理国情监测是为了使管理部门及时掌握不断变化的自然以及人文环境的变迁信息。地理国情监测包括数据的采集、存储、统计和分析等多项内容。其中数据分析包括对数据基本统计分析以及数据挖掘。作为深层次数据分析和挖掘的有效工具,空间聚类分析可以很好地分析数据之间的内在联系。本文选用热点分析,对规划容积率与土地利用数据进行分析,得到规划数据的空间聚集性结果与土地利用数据之间的关系,为地理国情监测数据分析提供参考。
