Based on field survey and remote sensing survey in 1984,we analyzed present situation and changing characteristics being of the Great Wall of Ming Dynasty in Beijing. The results show that about 7.02% of the wall is well-preserved (about 25861 m); 31.5% of the wall is slightly or moderately dam-aged (about 115989 m); 61.5% of the wall is badly damaged (about 226379 m). This paper analyzes the dynamic change of the Great Wall of Ming Dynasty. It shows that the damaged situation of the Great Wall of Ming Dynasty in Beijing is serious. From 1984 to 2004,the well-preserved wall is decreased by 33206 m (decreased by 56%); badly damaged wall increased by 51207 m (increased by 67%). Finally,this paper analyzes the influence factors of damaging Great Wall. The conclusion is as follows: The damaged Great Wall is generally near the roads and villages,small slope,and easily arriving land.展开更多

Historically, the land was fought over by the nomadic and the agrarian peoples of the region. The Yansui section of the Ming Great Wall and thirty-nine fortified encampments along it were built during fighting between the Mongols and the Han people. As all of them were located along communication lines vital to economic development, they played an important role in politics, the economy and transport over three hundred years of Ming and Qing rule. However, they fell into disuse in the late Qing and the Republican period and are now in ruins. The main reason underlying their decline was that the sites had been chosen for their defensive value, so the subsequent northern expansion of China’s borders and structural changes in the border economy hastened their decline. Thus the rise and fall of these fortified towns at the intersection of the agrarian and the pastoral regions was closely related to imperial political and military activity and was in line with ethnic and tribal movements and migrations and the evolution of civilizations. In sum, the reasons behind the demise of these fortified towns and camps were highly complex and usually involved multiple factors.展开更多
