蘇北地區新石器時代至商周時期 95%遺址分佈在2m 以上的海拔區，青蓮崗 文化至商代以2-5m 處遺址數量最多，但周文化時期5-20m 處遺址數量最多。這 一分佈狀況的變化可能暗示在周文化時期經歷過海面較高或鹹水入侵的環境。青 蓮崗文化時期，有9 處遺址分佈於前人確定的該時期海岸線以東。大汶口文化和 商文化時期前人確定的海岸線距該時期最東部遺址聯線有10-30km 之遙，遺址分 佈與沉積學確定的古岸線之間存在明顯的不吻合現象。蘇北在大汶口文化期間經 歷了文化低潮，遺址數量僅有10 處，長江三角洲在這一時期主要遺址卻從崧澤 文化的47 處增至良渚文化時期的124 處，兩地遺址數量存在截然不同的變化。 蘇北與長江三角洲目前均未發現7kaBP 以前的新石器遺址，在整個新石器時代 至周代，蘇北的中部廣大區域迄今也極少發現人類遺址，可能與蘇北中部長期存 在射陽湖和大縱湖或與黃河及淮河洪積物淹埋古遺址導致難以發現有關。蘇北周 文化時期遺址數量猛增與周公、周成王東征後周人向蘇北平原大量移民有關。上 述問題值得進一步深入研究。

Ninety-five percent of archaeological sites were located on altitudes above 2m (a.s.l.) from the Neolithic Age to Shang-Zhou Dynasties in North Jiangsu Province. From the Qingliangang Culture system to Shang Dynasty, most sites were located on altitudes 2-5m (a.s.l.) but most sites were located on altitudes 5-20m (a.s.l.) for the Zhou Dynasty. The distribution of sites infers that the study area perhaps underwent an environment of higher sea level or salt water intrusion in the Zhou Dynasty. During the Qingliangang Culture system, 9 sites were located to the east of the coastline at that time as determined by previous scholars. The coastlines of the Dawenkou Culture system and the Shang Dynasty determined by previous scholars are 10-30 km away from the line connected by the easternmost sites. So the site distribution is not identical to the paleo-coastline as determined by previous scholars’ sedimentological method. There is a cultural low tide with 10 sites barely during the Dawenkou Culture system in Jiangsu Province, but at the same time, the number of sites increased from 47 of the Songze Culture system to 124 of the Liangzhu Culture system in the Yangtze Delta. So the change of numbers of sites for the two areas is completely different. The temporal-spatial distribution of Neolithic sites shows a long period of absence of human settlements during the early Holocene on the North Jiangsu Province and the Yangtze Delta, and the areas have not been colonized until 7kaBP. On the other hand, up to now, only few sites during the whole Neolithic Age to Shang-Zhou Dynasties were found in Central North Jiangsu Province. It is possibly related to the presence of Sheyang Lake and Dazong Lake during all these periods, or related to diluvium from the Yellow River and Huai River which makes it difficult to find the buried sites. The rapid rise in the number of sites during the Zhou Dynasty is a result of more immigrants from Central China to North Jiangsu Province after the eastward fighting by Emperors Zhou Gong and Zhou Chengwang
