基于GIS和可视性分析的鄯善县烽燧系统研究

The Visibility Analysis of Beacon Tower System Based on GIS and Viewshed Analysis in Shanshan County

文章以鄯善县为研究靶区,以烽燧系统为研究对象,利用GIS方法,对各烽燧遗址进行可视性分析,对单个遗址的视觉范围及不同遗址间的复合视觉范围进行对比,研究各烽燧遗址之间的关系及各烽燧遗址的功能,并利用可视性分析方法确定烽燧系统信息网络的传播路径。结果表明:研究区烽燧遗址传播方式是以外围烽燧为信息源,以点状散射方式向内部各烽燧遗址传递,并沿火焰山山南山北分为两条线。其最佳传播路径为:以赛克散土墩烽燧、柯柯亚烽燧和二塘沟烽燧为前哨向研究区中心地带传递至疙瘩台烽燧、三十里大墩烽燧、东湖烽燧、库姆塔格烽燧、克其克烽燧、汉墩阿克都烽燧、连木沁烽燧、汉墩大夏墩烽燧及土尔坎尔孜烽燧,再南北桥梁苏贝希烽燧至山南吐尔买来烽燧、阿其克烽燧、阿萨协亥尔烽燧,最终至最南端迪坎尔烽燧。

Taking Shanshan County as the research target, this paper takes the Fengsui system as the research object, uses the GIS method to carry on the visual analysis to each beacon ruins, compares the visual range of single site and the composite visual range between different sites, studies each beacon The relationship between the sites and the function of the beacon ruins, and the use of visual analysis method to determine the beacon system information network propagation path. The results show that the mode of propagation of Fengshe site in the study area is from outside Fengsui to the information source, and transmits to the inside of the Fengshe site by point scattering, and is divided into two lines along Nanshan Mountain in Huoyanshan. The best route of transmission is as follows ： the Xike- san Mudunfeng, Kekeya Fengshe and Ertanggou beacon are sent to the center of the study area to the beacon station Fengshui, Shidili Dadun Beacon, Donghu Beacon, Ge-Feng Sui, grams of grams of beacon, Han pier Ake are beacon, even wood Qin Feng Sui, Han Dun Xia Tun Feng Sui and Tuerkanzai Feng Sui, and then north and south bridge Su Beixi Feng Sui to Shannan Turpan bought beacon, A Its grams of beacon, Asa Association Hail Feng Sui, eventually to the southern most Digal beacon.
