Research on Current Situation Investigation by Remote Sensing and Division Protection Zone of Great Wall of Ming Dynasty in Beijing

By utilizing SPORT5 and aerial images, Great Wall of Ming Dynasty in Beijing has been investigated in detail and current distribution of Great Wall has been reported. In this paper, DEM is assisted to extract Great Wall information and the length of Great Wall has also been calculated. It studies the relationship between Great Wall and the surrounding land use, villages, roads, terrain by using GIS spatial analysis method. Finally, the influence weight of every relevant factor is calculated by AHP(Analytic Hierarchy Process) method and this thesis sets up buffer model and confirms the protection zone, all these has proposed scientific basis for the protection, management, and investigation of Great Wall in Beijing.
