The archaeological project of the ancient city site in Ningbo was established. From this year to 2016, the city will carry out archaeological investigations, exploration and excavation work to confirm the specific location of the three city sites and their preservation status, and sort out the development track of ancient cities in Ningbo for future urban development and ancient China. The study of the city site provides theoretical support and physical illustration. This is the second active archaeological project for the ancient city site in Ningbo. According to the literature, the three ancient sites of the ancient city of Minjiang, the old rule of Jixian and the old rule of Jixian are located in the area of Lushan, the border of Baidu, Yinzhou and Beilun Districts of Fenghua City. The ancient city of Yuyao, located in the old town of Yuyao, and the ancient city of Wangjiaba Village in Cicheng Town, Jiangbei District, which has been confirmed by archaeology, constitute the main city before the Jin Dynasty in Ningbo. Earlier, the archaeological work of the ancient city of Ningbo in the ancient city has made important progress, confirming the specific location and the age of the founding of the city, and pushing the history of Ningbo's regional construction to the Warring States Period more than 2,000 years ago. This is basically consistent with the relevant records of the local literature of later generations, which can be mutually confirmed, and this achievement has also been widely recognized. The archaeological site of the ancient city sites of Minjiang Ancient City, Jixian County and Jixian County is to understand its location and preservation. According to Wang Jiehua, director of the Municipal Institute of Cultural Relics and Archaeology and the leader of the archaeological project, Mingzhou City was established in the Tang Dynasty. In the present Ningbo area, there were successive cities, such as the sentence, the 鄞, the 鄮, the Yuyao, and the cities. Many of them no longer exist. Although they are documented, they are not clear enough. There are many contradictions and controversy. For example, some scholars believe that the rule of the county after the relocation of Longan in the Eastern Jin Dynasty, the rule of the county in the Sui and Tang Dynasties, and the Ming Dynasty in the first year of the relocation of Tang Changqing were once located in the Minjiang River. Some scholars believe that the Lijiang River is fundamentally historical. There is no governance at or above the county level. “Where is the old rule of Jixian County and the old rule of Jixian County? What is the preservation status? Is there any city in the area along the Lancang River? If so, where is the city? These disputes need to be confirmed and clarified by archaeological means,” said Wang Jiehua. It is reported that the archaeology will first sort out the historical documents and word-of-mouth legends, determine the approximate scope of the three city sites, and then through field investigations, archaeological exploration and necessary excavation, and use modern means such as aerial remote sensing technology to try to confirm its specific location. The specific plan is: from 2013 to 2014, focus on the archaeological work of the ancient city of Minjiang, and complete the "sentence of the city - archaeological investigation and exploration report"; from 2014 to 2015, focus on the archaeological work of the old county of Jixian; 2015 to In 2016, we will focus on the archaeological work of the old town of Jixian County; after 2016, we will publish the "Ancient Archaeological Survey and Exploration Report of Ningbo City Site" and "Ningbo Ancient City Research", and explore the establishment of a geographic information database for the ancient city site in Ningbo.
