摘要
利用C4.5决策树分类算法和GIS组件Super Map Objects,开发实现了基于连续文化序列的空间数据挖掘系统,运用此系统对郑州-洛阳地区史前四个连续文化时期的聚落进行了数据挖掘,提取了聚落遗址面积的分类规则,并根据这些分类规则和聚落的空间分布情况对四个文化时期的I级聚落进行对比分析,得出了I级聚落的空间分布特点,即I级聚落中的一些特大面积的聚落朝着中心聚落的方向发展。
Using classification algorithm C4.5 of decision tree and GIS components SuperMa PObjects, the spatial data mining system based on continuous culture settlements is developed. The system is applied to the data mining for the prehistoric settlements of the four culture periods about Zhengzhou-Luoyang region. The area classification rules of the sites are excavated. The spatial distribution characteristic of level-Ⅰ settlements are gotten by contrasting and analyzing the classification rules and the settlement distribution of level-Ⅰ settlements. The characteristic is that the large area settlements of level-Ⅰ settlements are expanded to the central settlement.
