中国公路自然区划GIS研究

GIS Study on Chinese Highway Natural Regionalization

公路自然区划的主要任务是揭示公路工程自然环境的区域分异规律,为公路建设决策提供科学依据。中国公路自然区划GIS(HR-GIS)的研究则可解决区划指标定量化的关键问题。根据公路自然区划的类型体系和研究方法,研究了HR-GIS集成方法和总体框架;提出了空间数据库集成开发框架,实现了对海量数据的有效管理;提出了适合区划研究的空间数据挖掘方法,完成了区划环境参数的定量计算;基于ArcGIS Engine技术开发完成了中国公路自然区划GIS,实现了空间分析、区划信息查询等功能。

Revealing the regional difference of the natural environment of highway engineering is the main task of highway natural regionalization.At the same time,highway natural regionalization can also provide scientific basis for highway construction decision.GIS for natural regionalization of Chinese highway（HR-GIS） can solve the key problem of quantification of regionalization indices.The integration method and the framework of HR-GIS are studied according to the guideline and the research method of natural regionalization for Chinese highway.Based on object-rational model,the spatial database has been built for massive data management.The spatial mining methods suitable for the natural regionalization research are put forward to accomplish quantitative calculation of environmental indices.Using ArcGIS Engine technology,the HR-GIS has been developed and completed,which has realized the functions such as spatial analysis and information inquiry of natural regionalization.
