At present, the methods of spatial distribution and evolution of ancient villages based on the application of GIS tools and perceptual knowledge are difficult to explain the complex social ecological system (SES) of ancient villages, it is Mainly due to the lack of identification of the key elements and quantitative evaluation of the complex ancient village SES. The ancient villages in the Jinjiang Valley are typical ancient village clusters derived from the prosperous trading system in ancient times. The highly integrated village formation starts from the important supporting background of the regional spatial-economic-social system. In this paper, the prototype analysis method is used to construct a comprehensive data set for the evaluation of the social ecological system (SES) of ancient villages, and combines 22 representative heritage sites, quantitatively identify the prototype of SES prototypes of multiple ancient villages. Analyze key elements such as cultural background, political events, economics and trade, and nested combination with SES prototype (for example, the prosperity and sudden change of SES in Political Event-type ancient village, the stability of SES in Natural flow-type ancient village, etc.), Analyze the interaction between the prototype elements, quantify the function, economic, social, and cultural connection modes of the ancient village ecosystem. This article provides a path method with strong explanatory power for the SES study of ancient villages, and It provides a basis for the protection and development of regional ancient villages.
