Through establishing data models , this article directly illuminated that nanjing ming dynasty circumvallation is provided with rather high quality for development and protection .

通过数据模型的建立,直观地说明南京明城墙具有较高的开发和保护性.

Its prominent sign that differs from the general settlement site is circumvallation . And the connotation of the castle tells us that the development of it is a little higher than the general settlement .

它区别于一般聚落遗址的显著标志就是城墙，而且从遗址的内涵来分析，这些有城墙的聚落发展水平要略高于一般性聚落。

Performance : I used the water of river jinjiang to wash the ancient circumvallation , to uncover the typical different symbols of historical and modern periods .

具体实施：我用锦江河水在古城墙上清洗出历史与现代不同时期的典型符号。
