Research On Characteristics And Value Of Water Conservancy Projects In Yunnan Province

China has been a big agricultural country since ancient times,and water conservancy construction is the foundation of agriculture.In China’s long-term water conservancy construction,many water conservancy projects have been left,and a considerable part of them are still in use.In recent years,with the rise of the cultural heritage protection movement,especially the Dujiangyan,the Grand Canal and other water conservancy projects as the main water conservancy projects have been rated as world cultural heritage,and the public is paying more and more attention to the heritage attributes of water conservancy projects.But at present,the basic theories and related value research on water conservancy engineering heritage have not formed a system,and the research objects are mostly concentrated on large-scale water conservancy facilities that have been rated as cultural heritage,and rarely involve local water conservancy engineering heritage.The research on the provincial water conservancy project heritage is basically blank.The thesis first explains the concept and connotation of the water conservancy engineering heritage and explains the impact on the water conservancy engineering heritage of Yunnan Province from four aspects: climate and topographic conditions,social systems,water conservancy technology,and water conservancy project management.Secondly,by combing the history of water conservancy in Yunnan,the water conservancy development of Yunnan Province is divided into the initial construction period,the middle development period and the rapid development period.In the actual investigation,the list of ancient water conservancy projects and water conservancy heritages in use at the national,provincial and Yunnan Province levels was used as clues.Through field investigations on the conservation status and problems of Yunnan water conservancy heritage,the current characteristics of the water conservancy project heritage in Yunnan Province were summarized.And select the typical water conservancy engineering heritage in Yunnan Province,mainly from the historical evolution and engineering characteristics of two parts to carry out the research of key cases and summarize the overall characteristics of the water conservancy engineering heritage in Yunnan Province.Finally,the basic value and extended value of water conservancy engineering heritage are explored on the basis of characteristic research.
