GIS在甘肃省公路自然区划研究中的应用

Applications of the GIS Technologies in the Physico-geographic Regionalization of Gansu Provincial Highway

自然区划研究涉及到水文、气象、地理、地质、地貌等多方面的因素,以往定性为主的区划方法已经无法适应数字地球时代高度信息化的要求,必须在大量空间数据的基础上进行定量分析。这就需要能够综合管理、储存、显示、分析和模拟地理空间数据的强大工具。地理信息系统技术正是基于这一实际需要而被全程地应用到甘肃省公路自然区划研究中的。G IS的应用主要体现在:①空间数据的采集与管理,最终形成甘肃省公路自然区划数据库;②基于空间分析计算各类环境参数;③利用G IS技术编制甘肃省公路自然区划地图集;④基于面向对象的VB编程技术和组件式G IS技术MO自主开发的专业地理信息系统平台。

Physico-geographic regionalization need synthetically analyze multi-aspect factors such as hydrology, meteorology, geology, physiognomy and natural disasters. In the age of digital earth, the traditionally qualitative method on physico-geographic regionalization cannot meet the requirement of informatization with high deg powerful tools are required geographical and spatial data. ree, which need the quantitative analysis based on mass spatial data. So the to integratedly manage, storage, display, analyze, and simulate the Geographical Information System （GIS） is the best solution means, which is fully used in the study of the physico geographic Regionalization of Gansu Provincial Highway. The applications mainly include spatial data acquisition and management and as a constructed. Kinds of environmental parameters are calculated based on the which is the key of quantitative analysis. The atlas is compiled based GIS and an explicit platform to exposit the developed based on object-oriented result a spatial database is spatial analysis functions, computer techn research results. A thematic GIS with visual program technology of VB and independent ologies. It copyright ComGIS technology of MapObjects. Spatial database, atlas and thematic GIS would promote the application of the research results of the highway＇s physico-geographic regionalization in Gansu Province.
