摘要:农业物流的发展具有现代物流信息化、网络化、智能化的基本特征,现代农业物流的智能化发展趋势使构建基于数据挖掘的农业物流地理信息系统(ALGIS)具有非常重要的现实意义。本文采用VC+MapX构建基于数据挖掘的ALGIS,阐述了ALGIS构建过程中地图坐标系的定义、地图对象的操纵、地图数据的加载等基本过程,并对基于数据挖掘的ALGIS框架结构进行分析。论述了该系统作为数据挖掘的思想、方法与传统GIS的有机结合的基本特点,分析了数据挖掘与现有GIS数据分析的区别和联系。考虑到农业物流分布地域广、品种多等特点,对基于数据挖掘的ALGIS实现关键技术进行分析,在确定主题域的同时对维度和数据立方体进行创建。本系统的研究开发在于应用数据挖掘技术和可视化的农业物流地理空间信息,为决策管理者提供可视化的、可靠的决策支持服务。

Abstract: The development of agricultural logistics has such important basic characteristics as information-based, networking and intelligent of modern logistics. The intelligent trend of modern agricultural logistics makes the development of Agricultural Logistics Geographic Information System (shorter form ALGIS) based on Data Mining (shorter form DM) of great practical significance. The ALGIS based on DM is developed with VC and MapX in the paper, then several basic processes of ALGIS development, including defining Map Coordinate System, manipulating Map Object, loading Map Statistics are expounded, and the structure of ALGIS base on DM is analyzed. Moreover, the basic characteristics bination with Data Mining though
