Construction Method of Evaluation System of Water Conservancy engineering Heritage

At present, socialism with Chinese characteristics has entered a new era, and the reform and development of water conservancy is facing new situations, new tasks and new requirements. With the establishment of the list of "Heritage Irrigation Structures" in 2014, the ancient irrigation system in China has been gradually excavated, and the irrigation engineering heritage of our country has reached 23 items. The protection and display and utilization of ancient irrigation heritage is conducive to transforming the advantages of historical and cultural resources into social and economic advantages and promoting the development of local economy. Through the collection of literature and field research, this article deeply studies the formation and characteristics of water conservancy project heritage, analyzes the value composition of water conservancy project heritage, and summarizes and extracts the indexes of water conservancy project heritage value, and this paper points out the principles of selecting index items. In this paper, the index system is divided into target layer, criterion layer, supplementary criterion layer and index layer. The target layer is five values, the criterion layer is the specific classification of the target layer, the supplementary criterion layer is the corresponding supplement of the criterion layer, and the index layer is the quantification of the criterion layer.
