在RS和GIS技术支持下,利用相关影像,采用监督分类和人机交互相结合的方法对研究区城镇信息进行提取,在此基础上从城镇体系的空间分布特点及空间集聚与扩散效应的角度,对研究区域的空间结构进行分析。研究表明,该城镇体系的空间集聚能力强于扩散能力。 With the help of RS and GIS technology, this paper uses the related images to extract the information of cities and towns by using the combination of supervised classification and human-computer interaction. Based on the analysis of the spatial distribution of urban system and the spatial agglomeration and diffusion effects , To analyze the spatial structure of the study area. Research shows that the urban agglomeration is more capable of gathering space than its capacity of proliferation.
