基于粗糙集的交通道路与城镇用地扩展关系分析

Rough Set-Based Research on the Relationship between Traffic Road and Urban Land Use Expansion

交通道路是城镇用地扩展的重要驱动力因素之一,对城镇用地的扩展具有积极的作用。城镇用地的扩展也不断地对交通道路的发展提出新的需求。目前,众多的数理方法和空间模型已用以研究交通道路与城镇用地扩展之间的相互作用。为了更加有效地分析交通道路与城镇用地扩展的作用关系,以更加有效地研究交通道路与城镇用地扩展的相互作用程度和模式,需进一步探索新的技术方法和手段。本文利用粗糙集理论,以广东省城镇化问题为例,从一个新的角度来研究交通道路与城镇用地扩展之间的关系。结果表明,使用粗糙集抽取的反映交通道路和城镇用地扩展的决策规则可以有效地反映交通道路与城镇用地扩展的关系,对于城镇化的研究具有一定的指导作用。

Traffic road plays an important role in transportation and is a major driving force of urban land use expansion.Therefore,traffic road has great impact on urban expansion and development.Also,urban expansion has new demands for the development of traffic road.The relationship between traffic road and urban land use expansion is complex and uncertain,so we need to study it with a variety of research methods and from various aspects.Currently,a large number of mathematical methods and spatial models have been effectively used to analyze the relationship between traffic road and urban land use expansion.In order to analyze the interaction model and impact of traffic road on urban expansion effectively,however,new technical methods should be explored.Rough set theory,proposed by Pawlak in 1982,is an extension of set theory in analyzing data with insufficient and incomplete knowledge and has been demonstrated to be useful in fields such as pattern recognition,machine learning,and automated knowledge acquisition.Rough set theory does not need prior information in analyzing data and can derives the classification or decision rules according to a knowledge reduction procedure while keeping its classification ability unmodified.Thus,rough set theory can mine the objective and inherent rules contained in the data.Rough set theory is still not commonly used in research of the relationship between traffic road and urban land use expansion.In this paper,urbanization of Guangdong Province is taken as an example and the relationship between traffic road and urban land use expansion is studied with rough set theory.The result shows that the decision rules of traffic road and urban land use expansion extracted with rough set theory can effectively reflect the relationship between traffic road and urban land use expansion and can provide some guidance on urbanization researches.
