Promote the archaeological research of Koguryo and Bohai Sea in Tumen River basin;
1 Temple was built in the 5th century, which filled the gap in the discovery of Koguryo archaeological remains in Tumen River basin. Temple No.2 first discovered the overlapping relationship between the early and middle-late Bohai Sea remains, which provided a yardstick for identifying the early Bohai Sea architectural remains in this area.
Temple 1 and Temple 2 have a certain * * time relationship, which can be regarded as a "typical profile" to improve the archaeological remains in this area from the 5th century to the10th century, providing an important support for perfecting the archaeological chronology of this period.
Promote the study of Buddhist archaeology in the Southern and Northern Dynasties, Sui and Tang Dynasties;
1 Temple is the first Koguryo Buddhist temple discovered in China and the earliest Buddhist temple site discovered in Northeast China. Ming Wadang was unearthed in June of Renzi year, which provided important evidence for studying the spread of Sanyan Buddhism to Koguryo. A large number of sculptures in the late Northern Dynasties provide important materials for discussing the influence of Buddhist material culture in the Central Plains on the northeast frontier region.
No.2 Temple is the first comprehensive exposure of the advanced Buddhist temples in Bohai Sea, which provides important information for studying the plane layout, architectural combination and structure of the advanced Buddhist temples in Tang Dynasty and exploring the burial system of ancient relics in China. The archaeological excavation of the temple site in Gucheng Village is of great significance to improve the overall picture of Buddhist material culture in the Southern and Northern Dynasties, Sui and Tang Dynasties.
Deepen the research on the relationship between Koguryo and Bohai Buddhism material culture;
The ruins of temples in Gucheng Village include the ruins of Koguryo and Bohai Kingdom, which clearly reflect the historical facts of the introduction and development of Buddhist material culture in Koguryo and Bohai Kingdom under the influence of the Central Plains.
It provides an important basis for clarifying the material and cultural relationship between Koguryo and Bohai Sea, and is of great value for showing the formation process of China's unified multi-ethnic country and safeguarding national historical and cultural security.
According to the chronological study of relics, it is speculated that the construction time of early Buddhist temples was not later than the early Bohai Kingdom. The late Buddhist temples were built in the middle and late Bohai Kingdom, and the abandoned age was not earlier than the late Bohai Kingdom.
