摘要
以低山丘陵革命老区四川省梓潼县为研究区,将影响城镇化空间发展因素分为交通、区域动力和地形3大类,分析并基于ASTER GDEM,ETM和基础地理信息数据,提取出国道、省道、县道、蔬菜果园区、生态旅游区、生态工业区、水系、坡度和地形起伏度9个因子;结合层次分析法模型计算这9个因子的权重,在ArcGIS 9.3中利用空间叠置分析法得出梓潼县空间格局适宜性分级和分区图。该方法的实现为科学定量评价低山丘陵革命老区城镇化空间格局模式提供了一种全新的解决思路。
With Zitong County in Sichuan Province,an old revolutionary base area,as the study area,the authors classified the factors affecting urbanization spatial development into three types,i.e.,traffic,regional dynamics and landform,and,on the basis of ASTER GDEM,ETM and basic geographic information data,extracted nine factors,namely national highway,provincial road,county road,vegetable orchid area,ecological tourism area,ecological industrial area,stream system,slope and degree of topographic relief.The weights of these factors were calculated in combination with Analytical Hierarchy Process（AHP）,and the spatial pattern adaptability gradation and zoning charts were compiled by means of spatial superimposition analysis in ArcGIS 9.3.The realization of this method has provided a entirely new workable means for scientific quantitative evaluation of urbanization spatial pattern model in the lower mountain hilly old revolutionary base area.
