GIS空间分析技术在地理数据处理中的应用研究

Consideration on GIS Spatial Analysis in Geospatial Data Processing

地理空间数据GIS的处理中,空间分析是其分析、模拟、预测和调控过程的基础理论和技术。空间分析大量时空模型的建立与应用是地学分析区域性或全球性地理问题的重要手段,是新的挑战和机遇。作者从空间分析的定义及空间分析的应用研究出发,认为现代地理学的应用离不开空间分析的支撑;另外空间分析日趋成为自然地理学深化研究、应用的重要技术途径。地学数据GIS的分析处理,须与有空间特征的时空模型、数据挖掘、可视化技术整合,以及关注多维信息空间要素关联性的多元应用。

As the core of managing spatial data in GIS, the field of spatial analysis in physical geography becomes broader and broader. In the geospatial data processing, GIS spatial analysis is the theoretic and technical basis for analyzing, simulating, predicting and regulating the spatial processes. The spatio-temporal data models for spatial analysis are the impotent means to analyse a series of regional or global geographical problems in geoscience, which bring new challenges and opportunities to physical geography. Viewing from the definition and application of spatial analysis, the author studies and explains definition and development trend of spatial analysis, and draws the following conclusion： Firstly, modern geography needs more and more spatial analysis technology while the field of spatial analysis in physical geography becomes broader. Secondly, the spatial analysis becomes a major technologic approach in the research of physical geography. The method of processing geospatial data must integrate with spatio-temporal model, data mining, visualization, and the relevance of factor in multidimensional information space. In the near future, the combination of spatial analysis technology and integrative research of physical geography not only widens the field of spatial analysis technology but also drives rapidly the development of Geo-information Sciences. In a word, the combination of spatial analysis and integrative research of physical geography has already been one of the most important trends in the development of both modern physical geography and geo-spatial information sciences.
