交通是一个国家的经济基础,是政治、外交、战争等胜败得失的关键。因此,研究齐国的历史,离不开古代交通的研究。以淄河和潍河为中心区的齐国,西北是黄河和低洼水漫之地,南面是泰沂山脉、沂沭断裂带、胶东丘陵及人工所建东西横贯的长城,东、北两面分别是黄海和渤海。以上这些地理单元(除沂沭断裂带)的阻隔,形成了一圈天然的屏障,也使齐国素有“四塞之国”之称。也正是由于这样的地理环境,才铸就了齐国的交通状况。 Transport is the economic basis of a country and the key to victory and defeat in politics, diplomacy and war. Therefore, the study of the history of Qi, can not be separated from the study of ancient traffic. The Qi and the Weihe River in the center of Qi State, the northwest is the Yellow River and low water flood land, the south is the Tianyi Mountains, Yishu fault zone, Jiaodong hills and built by the East and West across the Great Wall, east and north sides are Yellow Sea and Bohai Sea. Above these geographical units (except Yishu fault zone) barrier, forming a circle of natural barrier, but also to make the country known as “four plug the country ” said. It is precisely because of such a geographical environment, it has created the traffic conditions of Qi.
