Abstract
Lingjiatan ruins, with natural and artificial defense systems, early make use of “ located in Taihu Hill, surrounded by water on three sides of East, West and South”to show the geographical situation of defense. With the changes of climate and geological conditions, slowly moving back of water on both sides of the land and a dramatic increase of settlement population, the living area extends to the beach land of both sides of the land, resulting in the extinction of natural defense function, so the Lingjiatan ancestors will dig moats to strengthen its defense capabilities. As the late Neolithic settlement sites, its defense system has the certain social significance. In a transition node of large-scale moats and walls changing, its defense system is associated with the evolution of social structure and has more universal meanings.关键词
