城市空间扩展问题的遥感技术研究方法——以南京为例

The Research on City Expansion Using Remote Sensing Technology

城市空间拓展动力机制的研究有助于了解城市发展的内部规律,对城市建设具有重要的指导意义。常规的研究方法多以实地调查、地图测绘等为主,本文借助了遥感技术中光谱特征分异法帮助进行城市空间扩展的动力机制的分析。可以较好的追踪城市空间特别是城市边缘区的拓展变化情况。从而相对于传统研究方法达到及时、全面的要求。

In this paper,a new method of studying the urban expansion,i.e.the spectral analysis of remote sensing technology is presented.The detail is as follows,the urban expansion can be learned through the spectrum characteristics variation directly.And comparing with the traditional method,the remote sensing technique is more quick and comprehensive.The research on motivation of urban expansion helps a lot in understanding the internal rules of urban development,and can be used to monitor the development of the city.
