一种基于数据挖掘的城市生态系统评估模型

Estimate Modle of Urban Ecosystem Based on Data Mining

利用数据仓库和数据挖掘技术,针对城市生态系统,设计评估指标体系,构建指标数据采集的网络系统,设计数据仓库的体系结构,包括数据维表和事实表,在此基础上建立数据仓库的星形模型,搭建评估平台,并进行模拟应用,结果令人满意。

This paper designed a evaluation system for urban ecological system,built a network of indicators data collection system,use of data warehouse and data mining technology.Then designed the data warehouse architecture,including data dimension table and fact table.On this basis,bult the Star model of data warehouse and built the evaluation platform.In simulated application,it achived satisfactory results.
